April 8, 2016:Further to AAVSO Alert Notice 532, the AAVSO is requesting ongoing time-series observations of the enigmatic variable object KIC 08462852 (= KIC 8462852) beginning immediately and continuing through at least the end of 2016.
Details on KIC 08462852 (V=11.88) were given in Alert Notice 532.
Observations are requested in order to study not only the aperiodic fading events but also the behavior of the star outside of these events.
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.
