June 8, 2017: Dr. Milena Ratajczak (University of Wrocław) has requested AAVSO observers' assistance in monitoring the very bright (V = 4.23) and very unusual eclipsing binary HD 148703 (HR 6143, N Sco) during its infrequent primary and secondary eclipses scheduled for 2017 June 11 and June 14, respectively.
Thanks to a fantastic volunteer effort by Dr. Nikolai Samus (of GCVS fame) we now have available a Russian translation of the AAVSO Manual for Visual Observing of Variable Stars.
The AAVSO DSLR Observing Manual is now available in French!
Many thanks once again to Bernard Candela for all the hard work he put into producing this translation. We hope that our French-speaking members and observers will find this manual helpful and will share it with their colleagues.
May 24, 2017: ASASSN-17fp, discovered on 2017 April 28 and classified as a helium dwarf nova, was observed to be in outburst again on May 16 after fading 2.5 magnitudes from its original outburst. Dr. Tom Marsh (University of Warwick) and Dr. Elme Breedt (University of Cambridge) requested immediate time-series coverage.
Although this dip is over, the campaign is extended to request ongoing monitoring, as requested in Alert Notice 542 (20160408) and Alert Notice 532 (20151020). - June 2017
Correction: The original announcement of this Alert Notice included the incorrect assignment of observations made by David Boyd to David Blane. The attribution has been corrected in the observations below. We extend sincere apologies to David Boyd for the error. -- EOW May 17, 2017
