4th September 2012ngc6995 Veil NebulaWO132, 8x10 minutes in Ha ![]() 6th September Asteroid 2012 QG42 News release from the BAA Discovered by the Catalina Sky Survey on 2012 Aug 26, this relatively large near-Earth asteroid will be readily observable for northern hemisphere observers between September 4-14 during which time it will attain magnitude 15.0 or brighter. The object probably measures between 200-500 m across and is a current radar target. It will be brightest around September 10-12 when it will reach V=13.6 on average. It passes closest to us around 05h UT on September 14 at a range of about 7.4 lunar-distances (0.019 AU). 2012 QG42 is a potentially hazardous asteroid (PHA) and is unusual in that it passes very close to the opposition point on September 7. Due to the accurate pointing of the DDM60 mount I found this quite easily.
