Arto Oksanen's observation via baavss-alert:
From: "Arto Oksanen" <arto.oksanen at jklsirius.fi>
I observed this star last night with the 40 cm robotic telescope of
Hankasalmi observatory in Finland.
The star was pretty faint at mag 17 (unfiltered, USNOB1.0 R-reference) and
dropping to mag 19 in eclipses. I got four hours from 21 UT to 01 UT, but
the last hour or so is ruined by clouds. The orbital period seem to be near
1.87 hours.
