Event: Nova in Vela (ASASSN-17mt) and associated observing campaign
Discovered by: ASAS-SN (K. Z. Stanek (Ohio State University) et al.; ATel #10772)
Discovery magnitude: V=11.3, using data from the quadruple 14-cm "Cassius" telescope at CTIO, Chile
Discovery date: 2017 September 24.39 UT
June 15, 2017: Drs. Frederick Walter (Stony Brook University) and Paul Kuin (University College London) and colleagues have requested AAVSO observers' assistance in obtaining photometry of Nova Oph 2017 (TCP J17394608-2457555) in support of Target-of-Opportunity observations with Swift UVOT that have been triggered and are scheduled for the next ten days (2017 June 16 - 25), and possibly longer.

Event: Nova in the Small Magellanic Cloud (Tucana)
Discovered by: the MASTER-OAFA auto-detection system (reported by V. Shumkov (Lomonosov Moscow State University) et al. in ATel #9621)
Discovery magnitude: 10.9 unfiltered CCD
Campaign continued through 2017. Also, updated in Special Notice #419 (20160809) to encourage spectroscopy.
August 3, 2016: Dr. Noel Richardson (University of Toledo) and colleagues have requested AAVSO assistance in optical monitoring of the bright, colliding-winds binary V1687 Cyg (WR 140, HD 193793) as part of their multi-wavelength campaign on this system.
April 5, 2016: Further to AAVSO Alert Notice 536, close monitoring of the cataclysmic variable SS Cyg is urgently requested. Immediate notification of the beginning of the anticipated outburst is crucial and is requested.
The success of the multiwavelength (radio and optical) observing campaign on SS Cyg underway depends on immediate reporting of outburst behavior to trigger multi-site radio observations.
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.
