Alert Notice 606: Observing campaign on nova in Vela - ASASSN-17mt

November 17, 2017

Event: Nova in Vela (ASASSN-17mt) and associated observing campaign

Discovered by: ASAS-SN (K. Z. Stanek (Ohio State University) et al.; ATel #10772)

Alert Notice 582: Nova Oph 2017 photometry requested for Swift TOO observations

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.

Alert Notice 557: MASTER OT J010603.18-744715.8 = Nova in SMC (Tucana)

October 17, 2016

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

Alert Notice 546: Campaign on V1687 Cyg (WR 140)

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.

Special Notice #414: SS Cyg monitoring continues for radio campaign

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.

Special Notice #411: RT Cru observations need to be continued

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.
