Object name: NGC5247
NGC 5247 is a rather nearby galaxy in southern Virgo below my 15-degree limit. Due to clouds in the north I had open sky only to the south and seeing was above average allowing me to give it a try. It was on my list for two reasons. One it has two main arms but a third arm just floats not connected to the other two. Several spurs come off the two arms but this one seems unconnected to either. Arp had a category for such three-armed spiral so it went on my Arp-like to-do list. The other reason is the very odd small but sharply defined dust cloud that cut right across the gap between the northern arm and the core coming to a point near the core then expanding in a puff beyond the bright core region after disappearing for a bit. While I found many papers on this galaxy not one mentions this odd dust lane.
