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.

On images taken by J. Vales in the course of the Crni Vrh Asteroid and Comet Search program PIKA, on April 16, 2010 an unusually bright unknown object (mag. 12.5) was automatically detected. The object was near opposition, in an area searched by Catalina Sky Survey (CSS) just a day before.
