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.
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
March 16, 2017: Dr. Karen Collins (Vanderbilt University) has requested ground-based, follow-up observations of recently discovered exoplanet Proxima Centauri b. This exoplanet is a suspected Earth-size planet orbiting in the habitable zone of our nearest stellar neighbor, Proxima Centauri (V645 Cen). There exists a rough ephemeris of this target based on radial velocity measurements, so the predicted mid-transit times can vary +/- 6 hours. Therefore, it is requested that observations be as long as possible.
Dr. Greg Laughlin (UCO Lick Observatory/Transitsearch.org) and Dr. David Blank (James Cook University) are conducting a photometric monitoring campaign for exoplanet transits of HD 13445. The windows for possible transitare:
December 11 20:51 - December 12 05:00 (UT)
December 27 14:58 - December 27 23:36 (UT)
HD 1334 is located at RA 02:10:14.4 and Dec. -50:50:0.5 (J2000).

INTRODUCTION
Dr. Greg Laughlin (UC Santa Cruz/Lick Observatory & Transitsearch.org) has requested help in observing GJ 436 to look for transits of previously detected and undetected extrasolar planets.
