Detection
of superhumps in SDSS J083845.23+491055.5
on Oct 22/23, 2007
Following the announcement of an outburst of SDSS
J083845.23+491055.5 on CVnet, I started time-series
CCD observations of this target on October 22/23,
2007 at CBA Belgium Observatory, using one of the
observatory's 0.35-m f/6.3 telescopes.
My observations covered a time span of 4.5 hours.
They clearly show the presence of superhumps with an
amplitude of about 0.15 mag, hence classifying SDSS
J083845.23+491055.5 as a new UGSU-type dwarf nova.

Using Peranso,
I find a superhump period of 0.0721 +/- 0.0019 d
(ANOVA method).
I encourage follow-up photometry, to further
determine the characteristics of this system.
