Lightcurve results for Comet 2012 nj.
Period 5.03 +/- 0.04 hours. Amplitude 0.1 +/- 0.03 magnitude.
During July of 2012, I was curious if asteroid-type photometry would work on a comet. As a trial I chose comet 2012 nj. This was a comet that fairly weak cometary activity and was first thought to be an asteroid when discovered. I chose this one thinking that the weak cometary activity might allow the variations in the brightness of the nucleus to be observed. In the end I was only able to observe the comet on 2 nights, and one of those was of short duration. Some variation was observed however it is unknown if these have any relation to the nucleus rotation.
