M98 had a distinct core, although it didn’t appear stellar. It was aligned at a PA of about 160 degrees. The southwest edge was sharpest and it was brightest along the southeast spine. I couldn’t detect any mottling. The neighbors kindly left their porch lights on for me all night.
Located in Coma Berenices, M98 is considered to be a member of the Virgo Cluster, although it is approaching us at 125 km/sec. It was discovered in 1781 by Pierre Méchain. It is also cataloged as NGC 4192, UGC 7231, MCG+03-31-079, VCC 92, PGC 39028, h 1132, GC 2786, CGCG 098.108, IRAS 121112+1510.
