4th September 2012ngc6995 Veil Nebula
WO132, 8x10 minutes in Ha
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.
