Observation required

Postby Ernst Pollmann » Sat Sep 26, 2020 10:32 am

Dear colleagues,
observations of VV Cep are still relevant since the Halpha EW and the ratio V/R are showing a strong dependence on the orbital phase of the companion (attachments). At present we are in phase 0.78 (periastron = phase 1.0)
