Multicolor Observations of the Primary and Secondary Eclipses of OW Geminorum Multicolor observations of long period binary OW Gem are reported: fivebands photometry during the primary eclipse in 1995 and seven bandsphotometry during the secondary eclipse in 2002. Simple model of botheclipses gives most probably stellar temperatures about 7100K and 4950Kand the orbital inclination close to 89 degrees.
Photometry of OW Gem We report on the eclipses of OW Gem
The Primary Minimum of OW Geminorum in 2002 We report CCD photometry of OW Geminorum carried out between Dec. 17,2001 and Jan. 11, 2002. The observations cover the primary mininum,which occurred in the predicted moment. The next secondary minimum isexpected between Oct. 8 and Nov. 7, 2002 whose multicolour photometrywould enable more accurate photometric modelling of the system.
