2007年爆发前对霍姆斯彗星的连续监测

Continuous Monitoring of Comet Holmes from Before the 2007 Outburst

E. E. El-Houssieny, R. J. Nemiroff, T. E. Pickering

摘要:

17 P/霍姆斯彗星的爆发和随后的亮度演变已经被MMT天文台的全天照相机(皮克林2006)观测到。美国亚利桑那州图森市附近的霍普金斯大学。这颗彗星于10月24.38日以5.5等的极限视星等被拍摄到,并被相机持续跟踪,直到4小时后的日出。在此期间,彗星亮度达到视星等3.5。霍姆斯彗星在10月25.23日日落后不久被观测到,视星等为2.5,在接下来的三天里几乎保持不变。然后彗星开始慢慢变暗,并在2008年的前几个月被密集的时间覆盖。

英文摘要:

The outburst and subsequent brightness evolution of Comet 17P/Holmes has been observed using the MMT Observatory's All-Sky Camera (Pickering 2006) on Mt. Hopkins near Tucson, Arizona, USA. The comet was picked up at the limiting visual magnitude of 5.5 on October 24.38 and tracked by the camera continuously until sunrise four hours later. During this time the comet brightened to visual magnitude 3.5. Comet Holmes was next observed just after sunset on October 25.23 at visual magnitude 2.5 where it remained approximately constant over the next three days. The comet then began to dim slowly and was followed into the early months of 2008 with periods of dense time coverage.
