Messier Marathon 1998

This year, the date around the weekend from Friday 27 to Sunday 29th of March, 1998 gives a good opportunity to observe actually all 110 Messier objects, for observers of mid-northern latitude (20-40 deg). Unlike the last two years, no spectacular comet is present this time, but you can observe the planets Venus, Jupiter, Uranus, Neptune and Pluto also during this night. Meteors might be visible from the following showers: Eta Draconids, Beta Leonids, perhaps some Leonids-Ursids, Eta Virginids, or Pi Virginids. Comets visible, according to the JPL index of Currently Visible Comets, sorted by apparent magnitude (for March 28, 1998):

Supernova ! A very special bonus is the 12th-magnitude supernova 1998S, which occurred timely in the galaxy NGC 3877 in Ursa Major; this galaxy is also only about 12th magnitude, but many amateurs will be able to get it in a break in the marathon.

Hope these enrichments will be appreciated during your marathon session!
