Latest on Comet 103P/Hartley
October 22, 2010

Comet 103P/Hartley is currently in the middle of Auriga moving to the southeast at a little over 3° per day. With closest approach to Earth on Oct. 20 (0.121 AU) and closest approach to the Sun on Oct. 28 (1.059 AU), the comet is as big and bright as it will probably get for this return. Unfortunately, the bright Full Moon will make observing the comet difficult for the next week and a half.

Observation of a dust spiral structure in periodic comet P/2010 H2 (Vales)
May 12, 2010
We observed the comet P/2010 H2 (Vales) in moonless conditions on May 1, 2010 using B, V and R photometric filters, as well as with the clear filter on the 0.6 m, f/3.3 Cichocki telescope at the Crni Vrh Observatory. The exposures, all of 8 minutes duration, were tracked on the comet and obtained between 19:46 and 20:31 UT. The pixel scale was 0.93 arcseconds.
