Official announcement of this discovery was sent yesterday evening to all observatories by the IAU Central Bureau for Astronomical Telegrams on IAU Circular no. 6986. The comet, provisionally designated as C/1998 P1, is seen in the southern constellation Circinus (The Compass) and the magnitude is estimated at about 9.5. This corresponds to about 25 times fainter than what can be seen with the unaided eye. The comet is easily visible in small telescopes. The orbit (and therefore the current distance) is not yet known.
Observations of the new comet were made with the 1.54-m Danish Telescope at the ESO La Silla observatory, immediately in the evening of August 11. The observers were Hans Kjeldsen (Theoretical Astrophysics Centre, University of Aarhus, Denmark) and Hermann Boehnhardt (ESO La Silla, Chile).
