We in the UK London dig have found a correlation with NGC2847 in that we dated LISAMI6 to be 25DEC2013 +/- 1 day. We think the rest of the Traf cam pics (including London2847) are likely at the same time.
Do a night sky simulation for London around 24/25/26DEC2013
and you will see NGC2847 tucked in the constellation of HYDRA.
Quite a coincidence. Good hunting with your astronomy hobby. o7
