Reports from Gesei Observatory <April 4, 2002>

• Observation data: C/2002 C1(Ikeya-Zhang) and
C/2002 E2(Snyder-Murakami)

At last the sky became transparent. This would be the last view of Ikeya-Zhang in the evening sky. In a 20cm telescope there was a 4.5-magnitude star nearby and the comet was estimated to be about one magnitude brighter. Since its discovery, Ikeya-Zhang has always been visible for about half an hour in the northwest at twilight.
It has been rather difficult visually.

C/2002 E2 was visually estimated to be at magnitude 11.7 at 2 am April 5. It was very diffuse and fuzzy with a 1.5'-diameter coma. It has faded a great deal.

Let's observe C/2002 C1 in the morning sky at dawn.
