17.5" (5/22/93): fairly bright, large, irregular round or slightly elongated 
SSW-NNE.  Very unusual appearance as a large brighter knot of 0.8' diameter or a 
very eccentrically placed core is located at the NE edge.  The halo extends 
generally SW from this brighter spot.  About 3' diameter, no brightening at the 
geometric center.  A mag 14 star is just off the NE edge 0.8' beyond knot.  
Located 45' SSE of M101 and a member of the M101 group.
