Leonids from Mount Airy, Maryland 11/18/00

The Leonids put on an impressive display from Mount Airy, Maryland. The skies were clear with the big nasty moon lurking.

Counts were easily over 100 per hour with perhaps 350 or higher per hour (method = guessing).

I did do a few counts:
06:18:00 UT until 06:24 UT 5 Leonids
07:28:00 UT until 07:34 UT 10 Leonids WOW!
Effective visual FOV around 120 degrees.
Limiting Magnitude perhaps 5.0 ( 10 Pleaides counted)
I suspect the counts will indicate a good showing!
The tapes certainly indicate that!

A RealVideo of bright memorable Leonid can be found at the Near-Live Leonid Watching System or go direct to the actual movie URL. The actual tape is 1000 X better than the RealVideo movie which I hope to remake when I can think...

Leonids - radio and Visual - Nov. 18

Hello:

It sorta cleared here in Halifax and that gave me a chance to view them unfortunately from my balcony. Clouds and an odd shower did occur, but my luck was not with me trying to get photos, I'd point at Orion and they would fall elsewere, I would move the camera and , yep, the odd bright one would go through Orion!

Anyways, this is what I have so far. My star magnitude varied from 4 to overcast at 0700-0800 UT. Also damp and light pollution a bit noticable.

Radio Meteor Observations of the 2000 Leonid Meteor Shower

November 18th, 2000, 0700-0900 UT
Rockford Lake, Nebr. 40.227N, 96.581W, 1400 ft elevation.

Equipment: 1989 Chryster Minivan AM/FM digital radio and Winegard 13 dB RF amplifier and extended whip antenna. Frequencies used: 105.5 Mhz, 91.5 Mhz, other frequencies below 92 Mhz.

After last night's somewhat limited success, I decided to go all out and use my "Mobile FM-DX" system in my van. It tends to be rather sensitive, as those of you who heard the Omaha stations from the site of NSP can probably attest to. I left Beatrice about 1 a.m. (0700 UT), and while driving, I did a count of the radio pings. In about a minute or two, I had heard about 17, and by the time I arrived at my viewing site at 0716, I had heard 112 meteor pings! However, I saw more meteors (about 5) while driving out to my site than I did the entire time I was on station, as low stratus clouds were quickly filling the sky. I retreated into the van, and fell back on meteor ping counts once again. The number was fairly steady, with much of the time having more than 2 per minute. After about 0730, the number began to shoot up *very* rapidly, making counting rather difficult as often over ten pings were frequently recorded nearly every single minute! The first 4 digit number is the time (UT) and the number after the colon is the number of radio pings heard during that minute (ie: 0736: 17 means beginning at 0735 hrs UTC, 17 pings were heard during the following minute).

0700-0716: 112 (total, not using tape recorder) minute by minute loggings:

0717: 0  0718: 2  0719: 1 (1 vis.)   0720: 1  0721: 4  0722: 2  0723: 2
0724: 2  0725: 2  0726: 0   0727: 1  0729: 2  0730: 0  0731: 16  0732: 20
0733: 13  0734: 8  0735: 11  0736: 17  0737: 12  0738: 11  0739: 11
0740: 14  0741: 10  0742: 14  0743: 17  0744: 9  0745: 13  0746: 16
0747: 11  0748: 14  0749: 9  0750: 16  0751: 11  0752: 15  0753: 13
0754: 10  0755: 9  0756: 10  0757: 8  0158: 14  0759: 7  0800: 12  0801: 9
0802: 11  0803: 10  0804: 14  0805: 6  0806: 7  0807: 11  0808: 7  0809: 8
0810: 8  0811: 14  0812: 9  0813: 23  0814: 14  0815: 7  0816: 10

After 0816, the tape recorder's battery was getting rather low, but the high rate of 7 to 10 meteors per minute continued for another ten minutes or so before starting to decrease slightly. By 0845, the number had dropped to from 2 to 6 per minute, and by 0900, the sky had cleared, but very few visual meteors were seen. More than a few of these pings were long enough to get some idea of the kind of station doing the transmission. One burst in particular sustained a readable signal for about 5 minutes! The 1st hour total was 502 pings between 0700 and 0800 UT and the maximum rate per minute for the entire observation period was a whopping 23 meteor pings per minute!! During the "outburst" phase from 0731 to 0816, the rate averaged about 12 per minute, which would translate roughly into about 720 per hour. From my brief visual observations, I would say that I was detecting between 3 and 4 times the number of meteors which an individual might see visually, since many were brief and probably were being drowned out by the moon. This is by far the most intense radio meteor shower I have ever heard. Clear skies to you.

Leonids 2000, From Northeast Penna

The promise of a clear skies for this year's meteor shower did not look good. Heavy clouds covered the region all of the daylight hours and into the early evening. A small break in the cover occurred at 9:00 p.m. local time, only to cover up again by 10:30 local EST.

Weather maps and newscast showed a "tongue" of dry clear air following this front and preceding the next. It had been stable most of the day, moving slowly NNE. Other observers and I estimated it would reach over our position sometime in the early morning hours on Friday November, 17. It did just that.

Observing from a open field, the clouds, moving quickly, slowly broke up and were completely gone by 1:30 a.m. EST (6:00 UT). I started my first of three hourly observing runs.

The first hour was lack lusted, clouds covered 50 % of the Eastern sky the first half of the session. This did help cover some of the glare of the Moon. I set my observation point to the stars iota and chi Ursae Majoris, and could view the skies from Ursa Minor on my left to Lynx, Auriga, Gemini with the Moon for interference. More towards my right I can see Canis Minor, and sections of Monoceros and Orion. Used the star zeta Urasa Minoris to estimated limiting magnitude at 4.3. The total for the first hour was a dismal 5 Leonids and 2 sporadic.

I took a 12-minute break from the temperature, and the snorting of the deer behind me. I had parked my back too close to their wild apple tree for them to feed. The deer had moved on, only the howling of coyotes were heard from the rest of the morning. Resumed the second hour watch with my gaze in the same direction of the sky. Skies remained 100 % clear for the full hour. Estimated the limiting magnitude in that area to be 4.7 by using starts of Leo Minor and those around lambda and mu Ursae Majoris.

This second hour was most exciting. In the first half hour 16 Leonids were seen. Most were brighter than 2nd magnitude with long trains, some blue in color other with a orange/red hue. Trains averaged 5 to 8 degrees in length. The second half equaled the first with brilliant meteors and slow fading trains. There was a great flurry of activity at one point near the end of the hour. In the region just outside of the Sickle of Leo three 2nd magnitude streaked around the radiant in a matter of 20 seconds. The first was a 5 degree blue train meteor to the north, followed by two 7 degree orange colored meteors. One travelling east and on the left side of Regulus, the next seen above and right of Regulus travelling south southeast. They were some of the last to be recorded at the end of the second hour.

Not wanting to miss another display like this, the third and final hour began immediately after the second. Wide awake and adrenaline pumping, I set my sites towards lambda and mu Ursae Majoris. The meteors of the Leonids did appear but most were 2nd to 3rd magnitude, very few above 2nd. And most were short trains 3 to 5 degrees long. Colors of blue and orange/red still seen. There were long time stretches between bright meteors. Just as the hour was almost over the most spectacular meteor of the night blazed forth 10 degrees directly below Regulus a -6 to -8 Leonid swiftly streaked towards the eastern horizon. It ended with a brief terminal burst near -8 magnitude. The 15 degree orange and blue train lasted some 10 seconds before disappearing to the eye. This one was seen at 4:28 EST and by far the highlight of the morning.

Summary of observations for November 17, 2000 EST / UT

time EST / UT				  Leonids  Sporadic  Limit Magnitude
1:17 to 2:17 a.m. EST / 6:17 to 7:17 UT   5	   1		4.3
2:29 to 3:29 a.m. EST / 7:29 to 8:29 UT	  32	   1		4.7
3:30 to 4:30 a.m. EST / 8:30 to 9:30 UT	  28	   4		4.7

One other item to note. While watching the region of lambda and mu Ursae Majoris and point light object brightened to equal the star lambda. It was situated to the left of the star close to RA 10h 25m DEC 44' 00" I suspect it to be a satellite but did not see movement or find any trace of a moving object afterwards. This appeared at 3:03 EST.

11/18 Leonids from VA

Well, I just got back from the pines of southern New Jersey. From 1:30 to a bit after 3:15, they were fast and furious, often two or more at the same time, or one right after another, with an average hourly rate of well over 60 to 80. I probably saw about 100 in an hour and a half, despite the moon's interference. The ones I saw were almost all very bright, swift, covering long arcs, and with glimmering trains. Many were colored green or blue-ish. After about 3:15 the rate dropped down noticeably, to more like about 20 per hour, but they were still fairly bright. I also did a little experiment. I tuned my FM radio to a blank frequency. The radio 'pings' were much more frequent than the visual meteors, probably around 500 an hour for a while! Many of them corresponded to visual ones. That was kind of weird, like you could actually 'hear' the meteor. This was actually one of the best meteor showers I have ever seen.

I think I may have seen the same Taurid, because I did see one medium bright, slower meteor that definitely did not appear to be a part of the Leonids, and it was above Orion, which could have made it coming from a radiant in Taurus.

Viewing from a golf course in Reston, VA, under clear skies and a quarter moon (LM = 4.6) I observed 50 Leonids from 2:43-3:43 EST (UT 7:43-8:43). This is a pretty remarkable rate under these conditions, although perhaps not any higher a ZHR than the previous night (32 in an hour under a higher, brighter moon, according to a report from NE PA on SAA). Only 2-3 of these meteors were brighter than magnitude 0. A single bright Taurid was seen, and no sporadics.

The rate appears to have dropped after that: I observed only 3 Leonids from 4:00-4:15, when the cold finally did me in. All in all, a much better show than I expected!

California Leonid report

From Atascadero, CA. Midnight, PST.

Very pretty, but low frequency.

Clear skies with the moon still low and blocked by trees.

In 45 minutes of observing I witnessed ~10 Leonids radiating from the east. The 5 best of these were bright, grazing-type meteors. They would burst to life at Jupiter-like brightness (Mag -2 ??), promptly dim 2 or 3 magnitudes, then plow across the sky for tens of degrees leaving bright trails that persist for several seconds. Several other faint grazers were observed.

Not bad, but where's that STORM??? =:o

NASA's radio meteor detector audio stream has just picked up markedly, I guess I'd better get back out there and have a look!

Leonid Fireball sighting!!!

While driving to the observation site, I saw a huge leonid fireball flash in front of me at 11:09 EST. It was on the west side about 45 degrees above the horizon. It was incredible. Very bright, should be around -6 or so. It illuminated the road for an instant. I saw clearly the change in color from green to red to white. It's angular width should be about 1/2 degree or so. It was very short around 7 degree and was not slow but not that fast either. It left a trail for about 20 seconds. Maybe longer because it was hard see while driving and moon behind. But it was the most impressive fireball that I have ever seen. And I saw more than 200 during the 1998 storm. Well, then I saw quite a few that broke up in several pieces. But still this was not the same. It was almost divine. Had I saw it during the middle ages, I would have started my own religion. After that I spent from 11:30 to 5 am observing but only saw around 25 with some really bright ones. But the first one was worth it. Since I'm at work and only sleep 2 hours I'm considering whether to go out tonight for the saturday show or not.

Leonids from far east

I watched 10 Leonids this morning. It was not totally fine. Clouds interrupt the observing. From 3 to 5:30 (18h - 20.5h 17th UT), I could see only 40 min. All meteors I saw were brighter than 1 mag. Limited mag. was 4.5.
The number was more than I expected under this condition. I cannot say the exact number, but maybe the ZHR was around 50.

I saw a prediction by Mr. Hasegawa mentioned in an astro magazine "Gekkan Tenmon". It says the first maximun comes in 2h 18th UT, second larger maximum in 6h UT. The ZHR is more than a few hundreds. How will be the result?

Leonids from far east

Hello :
Here is another far east report...

Despite a less than ideal observation site and poor LM 4.0+ sky due to light pollution and clouds. I have managed to bag 8 Leonids and 1 SPO exceptional bright green fireball in Kranji, NW of Singapore.

There is absence of meteors seen from 11/17 UT 17-1900 hrs. The first Leonid started in 11/17 UT 19:34 right in the centre of Auriga leaving a visible wake. Activity peak around UT 20:10-20:15, 21:30-22:00 as twilight approaches...

I keep my centre of view in Auriga, avoiding the moon in the east.

All Leonids seen were swift, with typical trajectories of 20-25 degrees. Color seen ranges from orange-red to slight yellow white (did not observe the yellow-green as in 1999 Leonids). Maybe the colors are influenced by the dominant moon light.

I am surprise to be able to see such bright meteors with moon nearby!!

There is definitely heightened leonids activity....This year the leonids prvide llocal folks a chance to see Leonids in their 'back-yard' ie w/o travelling abroad.

Heavy dew 'dampens' my intention of video taping the sky.

Leonids in the pines of New Jersey

Hi All

Well, I just got back from the pines of southern New Jersey. From 1:30 to a bit after 3:15, they were fast and furious, often two or more at the same time, or one right after another, with an average hourly rate of well over 60 to 80. I probably saw about 100 in an hour and a half, despite the moon's interference. The ones I saw were almost all very bright, swift, covering long arcs, and with glimmering trains. Many were colored green or blue-ish. One really nice one actually drew a line straight through Jupiter and Saturn! After about 3:15 the rate dropped down noticeably, to more like about 20 per hour, but they were still fairly bright. I also did a little experiment. I tuned my FM radio to a blank frequency. The radio 'pings' were much more frequent than the visual meteors, probably around 500 an hour for a while! Many of them corresponded to visual ones.

Leonids count in Florida

Well it seems like they were a bust here. I recorded from 4:15-5:00 EDT or 8-9 UT. I only saw 2 and one was from Orion and not a Leonid. Viewing was not possible for the first 15 minutes because a cloud bank covered the Eastern half of the sky - it moved out (or cleared up) slowly but it is hard to say how much it covered. The only stars I could see in that direction were the stars in the question mark and they were faint so whatever magnitude they are was the max I could see.

Fri, 17 Nov 2000 06:54:11 -0500

I had about an 80 degree circular hole thru the clouds at 02:50 UT Nov 17, and saw 5 Leonids in 5 minutes.

4 were dim, maybe around mag 3.5 - 4.5, hard to say due to the moon light. One was around mag -3 or nearly as bright as Jupiter which was visible in the hole...

Tra le 02h10m e le 03h20m (UT), in 31m20s di tempo effettivo di osservazioni ho osservato 34 meteore, di cui 29 Leonidi con una magnitudine limite di 5.1, quasi una al minuto. Un bel bolide di -6/-7 ha rischiarato una nuvola. Diverse Leonidi avevano magnitudine negativa e con scie ben visibili (anche con la presenza della Luna).

Cieli sereni,
Roberto

Bolidi e Nubi

Come sapete tutti il massimo delle Leonidi e' vicino. I due bolidi osservati dai membri della Dutch Meteor Society fanno ben sperare.

Per chi volesse dedicarsi all'osservazione dei bolidi (spero tutti i partecipanti) consiglio di munirsi di una mappa stellare su cui riportare ora di osservazione, punto di inizio e fine traiettoria del bolide e durata in secondi. Ricordatevi di scaricare il modulo di segnalazione di ITASN in modo da poterlo compilare direttamente sul campo:

http://www.fis.unipr.it/~albino/documenti/bolidi_report2.html"> htp://www.fis.unipr.it/~albinpo/documenti/bolidid_report2.html

Non trascurate di segnalare direttamente a me o in lista i bolidi osservati: ogni dato perso rende inutile l'osservazione. Attenzione ai suoni elettrofonici: se udite un rumore in contemporanea con l'osservazione del bolide si tratta di elettrofonia. Cercate di condurre le osservazioni da luoghi privi di inquinamento acustico e luminoso.

L'unica incognita sono le condizioni meteo. Pare che al nord ci sara' una tregua da ora fino a sabato sera: correnti fredde provenienti da NW dovrebbero spazzare le nubi spingendole verso sud dove ci saranno piogge per le prossime 24h.

Qui a Parma, stamattina, c'era il cielo sereno all'80% ma ora sono sopraggiunte nuove nubi e ha iniziato a piovere.

Io osservero' dalle 00 alle 7 TMEC del 18, nubi permettendo. Fate altrettanto cosi' possiamo triangolare gli eventuali bolidi. Nelle osservazioni privilegiate i piu' luminosi, dalla magnitudine -8 in giu'.

WAT GEBEURDE AFGELOPEN NACHT?

Na een bijzonder heldere waarnemingsnacht vanuit De Bilt kon worden geconstateerd dat er weinig Leonidenactiviteit was te bespeuren. De aantallen meteoren lagen ver onder de 'stoute' verwachtingen die sommige wetenschappers hadden aangekondigd. Als klapper op de vuurpijl werden echter in de ochtendschemering enkele bijzondere heldere Leoniden waargenomen. Deze vuurbollen straalden in De Bilt kortstondig zoveel licht over het landschap dat het leek alsof er een bliksemontlading plaats vond. Op de Noordzee bevonden zich op dat moment ook enkele onweersbuien, maar waarnemers in de omgeving van Chaam konden bevestigen dat het bij de 'lichtexplosies om 06.56 uur en 06.59 uur inderdaad Leonidenvuurbollen betrof.
