1 Murawski, Gabriel Eccentric binary with apsidal motion. Min II at phase = 0.66 in 2019 and 0.63 in 1999. Min I elements given in the table. Min II elements: HJD 2458036.63 + 28.838 x E. Min II amplitude = 0.3 mag in R1 in 1999 and 0.5 mag in V and g in 2014-2019. Min II duration = 16%. Reflection effect between secondary and primary eclipse (amplitude V= 0.10 mag). J-K= 1.12; B-V= 1.80.
