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
