• Photographs of C/2001 W2(BATTERS) and C/2000 WM1(LINEAR) These photographs of C/2001 W2 and C/2000 WM1 were taken over a very short period of time available before the moon rose in the evening. The exposure time for C/2001 W2 (Batters) was 3 minutes. The photo shows a short diffuse tail coming from the eastern edge of the 13th-magnitude coma. This comet was found to have a 65-year period. C/2000 WM1 (LINEAR) now has a smaller coma but the tail is one-degree long. In the 20cm telescope at 60x it was at magnitude 6.5 with a 0.5-degree-long tail. It is accelerating toward the south and this is the last chance for a glimpse of it. |
