This bright nova, discovered on December 7.47 UT by Syuichi Nakano of Japan at photographic magnitude 6.5 (see AAVSO Notice 179), has been very well monitored by observers worldwide. Its optical light curve, created from observations reported to the AAVSO, indicates it brightened to about visual magnitude 5.7 by mid·Oecember, and then has slowly declined to magnitude 8.4 by February 7, with fluctuations as much as 1 magnitude in amplitude.
We have been informed by our member William Liller, Vina del Mar, Chile, of his photographic discovery, using PROBLICOM, of a nova in Lupus at magnitude 8.0 (average of two photographs, TechPan film plus orange filter) on September 19.02 UT. The 1950 position, precessed from the equinox 2000 measurements provided by R.H. McNaught and G. J. Garradd, Anglo-Australian Observatory, is
March 1, 2016: Ms. Deanne Coppejans (PhD candidate, Radboud University Nijmegen (Netherlands) and University of Cape Town) and colleagues have requested AAVSO observer assistance in monitoring several northern dwarf novae in support of their campaign to observe them with the Very Large Array (VLA) in their ongoing radio jet research. Their research on radio jets in dwarf novae has been discussed in AAVSO Alert Notice 505.
February 26, 2016: Dr. Jeno Sokoloski (Columbia University) and Mr. 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).
February 26, 2016: Dr. Donald F. Collins (AAVSO member, Swannanoa, NC), Dr. Robert Zavala (US Naval Observatory, Flagstaff Station), and Jason Sanborn (Lowell Observatory) request high time-resolution observations of the bright eclipsing star b Persei (not beta) during an expected secondary eclipse of the third star of the system as it is expected to pass behind the close orbiting stars of the system in the two weeks centered on March 7, 2016. Dr. Collins provides the information below.
