[Aavso-photometry] RE: New CV: SDSS J170213.26+322954.1 outburst

[Arto.Oksanen at tietoenator.com]

I started my observations tonight at 17:40 UT and got the first eclipse at 17:44 UT. 
The star is bright about CV=14.7.

Quick period calculation from David's timings gives P=0.1000(86).

I have a 'live' preliminary light curve at the observatory web site:

Another eclipse occurred at 22:31UT. There was a slow rise and fall of about 0.6 
magnitude between the eclipses. I have now lost it behind trees. I'll upload the 
data soon.

David Boyd (BDG)
