A successful earlier attempt at determining the rotation period of an asteroid encouraged me to try and determine the rotation period of an asteroid with non previously reported.
During the end of August and early September, 2016 four nights, were spent imaging the main belt asteroid 41331 with an estimated diameter of 5.5km - 12.5 km. At the time mag R was 16.6
Once again Brian Walker kindly checked my period determination which resulted in a period of 3.2961 hrs. Not quite a discovery in the sense of a comet or supernova, but hey I determined the value and I was he first to know it, that's got to be worth something!
The result was presented during a presentation I gave at the BAA ARPS Asteroid workshop on 24th September, 2016.
