[Aavso-photometry] TU Cas

[Michael Koppelman]

Well, I've had so little to report lately, I'll report on this. See  
the plot here:

These were 25 seconds exposures. I then averaged the data into 0.001  
day bins (about 90 seconds). There were 3 or 4 observations per bin.  
The total uncertainty prior to averaging was 0.015 mag. This was all  
from the comp star scatter. The shot noise of each observation of TU  
Cas was 0.0002 mag. After averaging the uncertainty was 0.008 or so  
per observation.

I have not checked where in the cycle I got, but there is a flare- 
like event which looks real to my eyes.

I will submit this data to the AAVSO database.

Cheers,
Michael Koppelman
