DEEP SKY DEEP SKY
An apparently asteroidal object of 17th magnitude found by the Catalina Sky Survey on 6 May 2005 was found to show cometary features. The comet reached magnitude 10.5. The comet was recovered by M. Masek, J. Cerny, J. Ebr, M. Prouza, P. Kubanek, M. Jelinek, K. Honkova and J. Jurysek at the Pierre Auger Observatory, Malarque with the 0.3m reflector on 9 April 2014. The comet can make close approaches to Venus, Earth and Mars. Its last close approach to Earth was at the discovery apparition in 2005, when it came to 0.10 au and in 2036 it will approach to 0.06 au. It will approach within 0.08 au of Mars in 2132 and approached Venus to 0.09 au in 1957. Date 10x10 mag Error Kphot mag Coma ' 29 May 14 16.46 0.14 13.3 0.2 19 Jun 14 17.05 0.21 15.4 0.2
