AAVSO ALERT NOTICE 170 (April 22, 1993)
1719-23 NOVA OPHIUCHI 1993 [V2295 Oph]
April 8, 2016: The symbiotic recurrent nova T CrB has entered a super-active state, and it is brighter and bluer than it has been since before its last outburst in 1946. Multicolor and visual ongoing observations are requested.
February 26, 2016: Dr. Jeno Sokoloski (Columbia University) and Mx. Adrian Lucy (graduate student, Columbia University) have requested AAVSO observations of the jet-driving symbiotic star V694 Mon (MWC 560), which is in outburst, in support of upcoming Chandra observations to investigate the state of the inner accretion disk during this outburst.
The Chandra observations are scheduled (preliminary schedule) for 2016 March 8 (7:17-14:13 UTC) and March 9 (2:20-9:17 UTC).
December 15, 2015: Further to AAVSO Alert Notice 503 and AAVSO Special Notice #409, Dr. Margarita Karovska (Harvard-Smithsonian Center for Astrophysics) urgently requests that multicolor and visual AAVSO observations of the symbiotic variable RT Cru continue.
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: 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: Discussion forum thread created for this campaign at Campaigns and Observation Reports: https://www.aavso.org/rt-cru-monitoring-campaign - Elizabeth O. Waagen, 21 May 2020
This campaign has been extended indefinitely. Dr. Karovska requests monitoring of RW Cru until further notice. - Elizabeth O. Waagen, 17 April 2020
