We announce another observation campaign of EE Cep which will be held in 2020. The ingress will start at about 7th March (JD 2458916.4), whereas the end of egress will be observed around 21st April (JD 2458960.5) with mid-eclipse around 3rd April (JD 2458943.19). Due to the duration of the previous eclipses, it is recommended to start the observations at least two months before the mid-eclipse and continue for four months. Attention should be paid around 20th May 2021 (JD 2459354.7) due to the fact that in previous epochs flux increase in I band was observed around these days. This phenomenon will start around 25th October, 2020 (JD 2459148.1) and end around 9 December, 2021 (JD 2459558.2). It is recommended to observe in Johnson-Cousin system with an accuracy of 0m .01 or higher
Monitoring: daily in BVRcIc from Januari 1st till end of June + Ic continuing monitoring from begin October 2020 till end of December 2021

This proposal was alrady submitted some weeks ago, but some clarification was needed regarding the monitoring in Ic
