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

[Jeremy Shears]

Conditions are not ideal in NW England this evening (2005 Oct 5), but I 
carried out time resolved photometry from 19.14 to 20.37 UT (clouded out at 
that point). I caught a complete eclipse and preliminary analysis shows the 
eclipse centred on 20.09 UT.

Best regards,
Jeremy Shears,
Cheshire, UK
