Remarks: |
| On February 3, 2009, U Geminorum was observed for several hours. We used
a GSO-Newton 200/800 telescope with a SBIG ST10 camera installed near Munich. The
exposure times for single images were 2 minutes. An L (IR-blocking) filter was applied.
In
these data, we found a new variable
star, an EW eclipsing variable. We continued to observe it on
March 21, April 13,
April 15, and April 21, with exposure times of 1 min.
On January 19, 2010, this star was observed again in the north of Austria with a
Carbon-Newton
(InterconSpacetec) 200/800 telescope and a SBIG ST10 camera, also with 1-minute exposures
and the same L filter.
Dark and flat field reductions were performed by CCDSoft and photometry, by MaximDL.
