July 25, 2018: John Strachan (Ph.D. candidate, 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 #2 campaign.

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.

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.
