Description:  North is to the lower left.
The core of this barred spiral galaxy was bright and nonstellar.  From the north west side of the bar an elongated bright patch extended a short distance to the north.  A gap with a very faint star in it seperated this bright area from the origin of the eastern arm which angled off to the south.  From the southeast end of the bar another arm curved away to the west and
north.  Immediately to the south of the origin of this arm another very faint star was seen.  As this arm passed a bright star to the west of the galaxy it became faint and very broad before narrowing and becoming very faint as it trailed away to the north.  An even fainter arm was seen about 50% of the time originating at the bright patch at the northwest end of the bar and extending a short distance to the east before fading into the surrounding sky glow.  The end of my observation of M 61 was signaled by a dull thud as the tube hit the wall of the observatory only 17 minutes after I began studying this beautiful galaxy.  Note added 5-4-00:  The star near the right side of the bar turned out too bright in the drawing.  It was equal in brightness to the star in the gap near the left side of the bar.
