EE Cep observing campaign 2020-2021

Active Dates: Feb. 28, 2020 – Nov. 30, 2021


Abstract:

Dariusz Kubicki (Nicolaus Copernicus University) has requested AAVSO observers' assistance beginning now in monitoring the long-period (5.61 years) eclipsing binary EE Cep for a campaign that he has underway. This campaign is in two parts, first for the eclipse itself occurring over the coming months, and second for follow-up to begin in December 2020.

Justification:

All photometric optical (UBVRI) and especially infrared (JHK etc.) data and spectra will be useful. Spectroscopic observations with high resolution (R~10000 or higher) are also recommended. Observing Hα, Hβ and Hγ lines and ion Na I doublet for analysis of line profiles will be useful.
