On 2010 April 16, Jan Vales of the Crni Vrh observatory, Slovenia, discovered the object at 13th magnitude. Observations using larger telescopes some hours later showed the object was slightly more diffuse than the adjacent stars and it was subsequently identified as a new comet, one that seems to have undergone an outburst of 7 magnitudes or more within a time interval of less than 14 hours. The orbit of the object shows that the parent body is one of the family of asteroids known as the Hildas, which are held in their orbit through resonance with the planet Jupiter. We may have witnessed an event whereby the asteroid in question has collided with a smaller body causing it to disintegrate into fragments, releasing dust and gas in the process. On the other hand, some internal process may have triggered what is essentially a cometary outburst.Date10x10 magErrorKphot magComa '
