Note: Note: Observations of V694 Mon are scheduled for 11 March 2020 with HST, and for 22 March 2020 with XMM. Please continue to observe as indicated in Alert Notice 695 but with the high-intensity coverage taking place March 9 through March 14 and March 19 through March 25. - Elizabeth O. Waagen, 6 March 2020
Note: As of 2020 March 2, Dr. Kenworthy asks that the campaign continue. He writes that "...the ring eclipse seems to have finished, but the star's overall brightness is slowly dropping. I don't think the story is over...the star is now 0.3 magnitudes fainter than its out of eclipse levels - still something interesting going on!" Please continue observations as described below until further notice. - Elizabeth O. Waagen, 2 March 2020
Note: Continued observations in all bands (particularly B and V) and spectroscopy are extremely important. Please continue nightly observations until further notice. - Elizabeth O. Waagen, 31 January 2020
Note: The exact schedules for the Chandra and HST observations of R Aqr (Alert Notice 689) are as follow:
Chandra (UT) Note that this date is EARLIER than given in Alert Notice 689.

Dr. Keri Hoadley (California Institute of Technology) requests AAVSO observers' assistance in obtaining B-band images of the star TYC 2597-735-1 over the next few weeks. This campaign needs to be accomplished before the target becomes unobservable in the West.
