  • There have been numerous reports of anomalies during transits of the planet TrES-1b. Recently, Rabus and coworkers' analysis of Hubble Space Telescope observations lead them to claim brightening anomalies during transit might be caused by either a second transiting planet or a cool starspot. Observations of two consecutive transits are presented here from the University of Arizona's 61 inch Kuiper Telescope on 2008 May 12 and May 15 UT. A 5.4 ± 1.7 mmag (0.54% ± 0.17%) brightening anomaly was… CONTINUE READING
