October 30, 2015: Further to AAVSO Alert Notice 503, Dr. Margarita Karovska (Harvard-Smithsonian Center for Astrophysics) informs us that the Chandra observations of the symbiotic variable RT Cru have been scheduled.
Note: AG Peg has not yet returned to its pre-1860 outburst visual magnitude of ~9.2, so please continue observations. - Elizabeth O. Waagen, April 20, 2021
Although the 2015 outburst is long over, ongoing observations are requested to see if AG Peg eventually returns to its pre-1860 outburst visual magnitude of ~9.2. - Elizabeth O. Waagen, April 11, 2020
March 13, 2015: Dr. George Wallerstein (University of Washington) informed us that the symbiotic variable BF Cygni has brightened considerably over the past few weeks, and he is currently obtaining spectroscopy of it.

Editor's Note: In the original e-mail, CBET 577 was incorrectly identified as IAUC 577.
U. Munari (Istituto Nazionale di Astrofisica, Astronomical Observatory, Padova) has asked AAVSO observers to monitor AG Dra until the end of its current outburst period.
Notes: Please continue to monitor RT Cru as it continues to decline slowly from its outburst that began in 2021 and after it returns to minimum. - Elizabeth O. Waagen, April 4, 2023; July 2, 2024
This campaign has been extended indefinitely. Dr. Karovska requests monitoring of RT Cru until further notice. - Elizabeth O. Waagen, 17 April 2020
