[Aavso-photometry] New variable discovered?

[Dave Lane]

Hi,

A few nights ago, quite by accident when inspecting the light curve of 
an asteroid, a new variable was discovered by my colleague Dan Majaess. 
This variable is not subtle, but over the course of a bit more than 3 
hours, it dropped in brightness (unfiltered) by nearly 0.8 magnitudes!

See: http://www.davelane.ca/aro/newvar2.gif (3 other check stars are 
also shown - SD is about 0.025)

In the next four nights it was "stable" at about V=16, except for the 
last observation last night when it jumped up about 0.4 mag! I have 
looked carefully at the 5 frames which are combined to make a single 
measurement and all individual 60-second frames indicate the same level 
of brightening.

Has anyone seen this sort of behavior before? I'm fairly new at this, so 
any idea what type of star this might be and what my next steps should 
be (other than MORE DATA!)?

Of course, it will be cloudy here for the next several days? Anybody got 
an automated scope that wouldn't mind adding this field to their late 
night observation list (in V). Transit is about 130am local.

Cheers,
