This sequence of 3 track-and-stacks was taken on the evening of October 30, between 21:41 and 23:09 UT. The image is a detail of our standard 22.5 x 15 arcmin field and shows minor planet 2006HU30 moving at a medium speed of 4.3 arcsec/min in northeastern direction. Each frame is a stack of 20 x 30 second exposures with the 16 inch Schmidt-Cassegrain and SBIG ST8-XME camera located on Guidestar Observatory.
Weather conditions not optimal at the beginning but improving during the night as the object was rising from 30° to 49° altitude. The image shows the time of mid-exposure for each stack.
