[Aavso-photometry] 1930+53

[Richard Huziak]

Hi Jim,

Of all the HMXBs 1930+53 or DM+53d2262 is one of the more active stars, 
and as such, one of the most sought after for data, so please continue 
on this star.  I will cc Gord Sarty and ask him to respond about 
behavior.  So far this star has shown an amplitude of about 0.1 mag in 
V, similar in other bands.  Thanks to all who have contributed the 
wealth of data on this star so far.
