Some photometry

After a very long period of cloudiness there was a clear night, but with a heavy surface fog. Visibility in the ground level was 250m in the near by airfield.

I took 30 * 2 min exposures with Johnson V -filter of the comet C/2012 V2 (LINEAR) and put them to MaximDL's photometry tool.

Here's the graph.
