Note: The astronomers request continued observations to ascertain whether or not the eclipse is completely over. - Elizabeth O. Waagen, 6 April 2021

Note: Please continue observations at a cadence of 1 observation per week until further notice. - Elizabeth O. Waagen, July 6, 2021
Please continue observations at a cadence of 1 observation per week at least through 2021 June 15. See the post by Principal Investigator Dariusz Kubicki in the forum threads for this campaign (URLs below). - Elizabeth O. Waagen, 2020 June 29
The eclipse of EE Cep has occurred but continued monitoring is requested to establish post-eclipse behavior. - Elizabeth O. Waagen, 2020 May 21
Note: Continued observations, particularly in B, V, and visual, are needed now and through the coming year. R Aqr is presently approaching solar conjunction and observations are very difficult, but they are extremely important as R Aqr is also approaching minimum. Please observe as long as possible now and pick up again as soon after conjunction as possible. - Elizabeth O. Waagen, 1 February 2021
