Analysis of my 3.5 hr unfiltered photometry run last night using the Kwee-van 
Woerden method in Peranso yields the following times of minimum:

JD 2453648.33832 +/- 0.00005
JD 2453648.43845 +/- 0.00003

giving Porb = 0.10013d +/- 0.00006 (2h 24m 11s +/- 5s)

The data is available on the AAVSO lightcurve generator as SDSS1702. There is no 
sign of a secondary minimum as observed in Arne's NOFS photometry - see 
http://arxiv.org/PS_cache/astro-ph/pdf/0407/0407071.pdf - and the light curve 
has a significantly different shape.

It will be very interesting to see how this system evolves as the outburst 
progresses.

Regards,
David Boyd (BDG)
