The comet 2012K5 LINEAR that I observed in first time has been positioned in northern part of Bootes. I observed a 10th magnitude coma and a dust tail stretched in north direction with length of about 5 arc minutes. The comet will get brighter gradually from now on, be expected to brighten about 8th magnitude in end of 2012.
