This list is NOT A PUBLICATION of observed minimas. It only shows activity of cooperating observers of eclipsing binaries.

B.R.N.O. times of minima are periodicaly published in Open Europen Journal on Variable stars and then data are displayed in O-C gateway.

Daniš S., 16. 4. 2020
v noci 14/15.4.2020 melo dojit k primarnimu minimu, pozorovan jen maly pokles jasnosti zpocatku pozorovani(~0.1m) odpovidajici moznemu S minimu. M0=51620.769, P=0.840374
Vrašťák M, 5. 5. 2013
4/5.5.2013 som pozoroval MZ Dra 1 hod pred a 1,5 hodiny po predpovedanom minime. Jasnosť hviezdy sa nemenila. M0=51620.769 P=0.84034 4/5.5.2013 I observed MZ Dra 1 hour before and 1,5 hours after predicted minima. The star was constant. M0=51620.769 P=0.84034
