Comet 81/P WIld
Comet 81/P Wild

Comet Wild 2 is a short periodic comet with an orbital period of 6 years. Before its close encounter with Jupiter during September 1974 his orbit was almost circular and had a 43 year period. But the gravitational pull of the giant gas planet made Wild 2 to a member of the inner solar system. In 2004 the comet was target of the NASA mission "Stardust", which took samples of the coma and returned them back to earth. Our image was obtained during a trip to southern france in February 2010 and shows a nice 1 degree long tail.

2006 HU30

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.

2006HU30 is an Apollo discovered on April 25, 2006 by the Catalina Sky Survey and confirmed by Peter Birtwhistle J95. Our follow-up-astrometry was published in the Minor Planet Electronic Circular Daily Orbit Update MPEC 2006-U95
