[Aavso-photometry] Possible new variable?

[Dave Lane]

I was doing a time series on two stars last night for Gord Sarty and 
Rick Huziak's campaign and my first choice of check star for the LPH058 
field seems to be variable. It was imaged in both B and V - see the star 
labeled "l" at:

http://www.davelane.ca/aro/images/*lph058b.gif
*http://www.davelane.ca/aro/images/*lph058v.gif

In both filters there is a general brightening trend of about 0.02 in V 
and 0.03 in B. The airmass increases until the data gap (the meridian 
flip) in the graph and then decreases towards the end **(ignore the last 
four points as the airmass was well over 2). **The star has a B-V of 
about 0.36 and the comparison star about 0.34.

SIMBAD doesn't come up with anything other than identifying it as GSC 
00154-00555 and as an A2V. Nothing in the NSV either. Another 
interesting point is that in the subset of the Henden sequence chosen 
for the finder chart, this star has the largest reported V error.

Being fairly new to this, is this the kind of thing that should be 
reported some how or should I continue to observe it or are there just 
too many unknown variables to bother with?
