[vsnet-outburst 2403] IY UMa charts
A quick note to visual observers using either the sxn Henden/Sumner charts
or the AAVSO preliminary charts for this field.
The star NW of the 136 comparison (10:43:25 +58:06:21) is actually a
galaxy. It is much fainter visually than would be assumed from looking at
the charts. This has caused me (and other observers) problems in recognizing
the field at times.
Regards,
Mike Simonsen
