Comet 1995 O1 Hale-Bopp 1998 Feb 21.441 120 sec exposure. North is up in this 22' X 15' field, false-colour palette applied to show detail in tail and inner coma. The dust in the orbital plane of the comet is still faintly visible as the more upright narrower portion of the tail ( also extends off the S side of the field) with the main dust tail angled more to the left (ENE). Taken with a 25cm f/4.1 Newtonian and HI-SIS 22 CCD from Loomberah NSW Australia, 151.05E 31.33S alt 845m ASL. Copyright 1998©Gordon Garradd

Images of Comet 69P/Taylor taken on 02/26/1998 at Osservatorio Astronomico "Don Paolo Chiavacci" Crespano del Grappa - ITALY- by G.Umbriaco and D.Bellio. The first image is the original image (sum of 10 exposures of 90 seconds, the first exposure was taken on 02-26-1998 at 20:45 UT) The second image is a false color version. All images were obtained with the 50 cm Newton reflector working at f/5 and CCD ST-4.

Statistics

Typically, about 1,000 individual users/computers access this page every day. These accesses create more than 15,000 entries per day in the access log. This amounts to an increase in the size of the access log of 1.5 Mbytes per day! However, the peak access rate during the C/1995 O1 (Hale-Bopp) apparition was >>30,000 users. The peak usage was more than 550,000 hits per day.
