June 30, 2017: Dr. Octavi Fors (University of North Carolina at Chapel Hill) and colleagues have requested AAVSO observers' assistance in following up on some targets from the Evryscope survey.
Note: This campaign is officially over, but the astronomers would appreciate it very much if observers could make an occasional observation of PDS 110. EOW March 29, 2018
Note: This Alert Notice was edited to add the magnitude range of PDS 110. EOW
June 16, 2017: John Strachan (Queen Mary University of London) and Dr. Guillem Anglada-Escude (Queen Mary University of London) have requested AAVSO assistance in the monitoring of three M dwarf stars as part of the Red Dots campaign.
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.
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.
