Alert Notice 571: Observations Requested of Exoplanet Proxima Centauri b

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.
