April 21, 2016: The Mira variable QX Pup (12.4-12.8 I - 14.5-14.7 I) is approaching maximum and was magnitude 13.038 I +/-0.026 on April 16.9723 UT (HMB, J. Hambsch, Mol Belgium). This star is the target of an observing exercise initiated by Arne Henden in 2008 to determine fundamental information on it (http://www.aavso.org/qx-pup).
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.
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.
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.
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.
