SDSS J170213.26+322954.1: eclipsing SU UMa-type dwarf nova in the period gap

Arto Oksanen's message:

Dear all,

I got two eclipses last night. In addition to the deeper eclipses reported 
earlier the star showed also 0.3 mag superhumps.
Period measurement with Peranso gives 0.1001 days for the orbital period an
d 0.1056 days for the superhumps.

I posted comparison of the two light curves on our web server:

Tonight seem to be cloudy here so I hope some other observers are able to
follow this very interesting target.

best regrds,

arto
