At that time it was a 10th magnitude comet, located Lua error in Module:Convert at line 272: attempt to index local 'cat' (a nil value). away from the Sun and Lua error in Module:Convert at line 272: attempt to index local 'cat' (a nil value). away from Earth.
The comet is notable for being one of the brightest visible to observers in the northern hemisphere since Comet Hale–Bopp in 1997.[1]
