Reports from Geisei Observatory <April 16, 2001>

• C/2001 A2(LINEAR)
This comet is moving south in the evening sky at the moment It was expected to become very bright, but it is still at 11th-magnitude with the coma 2' in diameter. The photograph was taken by a double exposure for 5 minutes each by the 60cm telescope on April 13. It shows a southward motion.

• 45P/Honda-Mrkos-Pajdusakova
This comet is very low in the western sky. It was not visible to the naked eye because of light pollution. With some difficulty the 60cm telescope captured it by a 4-minute exposure. The comet does not show the nucleus and is nebulous. The error margin of the measurements will be ±2". They are in line with Mr. Muraoka's revised orbit.
