Comet C/2017 O1 Finder Chart

Comet C/2017 O1 (ASASSN1) is now located between the constellations of Perseus and Auriga heading towards Camelopardalis (at the time of writing). This now places the comet within the circumpolar region of the northern sky giving observers the luxury of all night viewing.

The icy rock shines at around visual magnitude of 8.5 and will reach perihelion on 14th October. Unless anything unexpected occurs over the next few days, the comet is not expected to brighten much further. The current brightness of C/2017 O1 still keeps the object within the visible range of binoculars and modest sized telescopes although the comet does not boast much of a lengthy tail at present.
