Reports from Geisei Observatory <June 27, 2002>

• Photograph of 29P/Schwassmann-Wachmann 1
We received the news from overseas that Schwassmann-Wachmann 1, well-known for its outbursts, had brightened. We took a photograph of this comet on June 21 (UT) and the magnitude was estimated to be 13.5-14. This matches quite well Mr. Muraoka's magnitude prediction in the Comet Yearbook. Observations at Geisei Observatory have not been progressing well due to inclement weather and typical summer conditions unfavorable to astrophotography. I received hypersensitized TP6415 film from Mr. Katsuyoshi Yoshimi who lives in Matsubara City. I will resume observation soon after the end of the rainy season, while the film is fully sensetized. Mr. Yoshimi is an amateur astronomer, one of the very few who do hypersensitizing of film.
