Details:
Sunset clouds had been in the way for over a week, but they were gone last evening. However, when the Sun was setting yesterday, Mercury was only 8° above Rio`s horizon in spite of its current 14° elongation. To complicate things further, at azimuth 280°, where Sky Chart predicted it would be, a nearby building obstructs my horizon up to 6° altitude. In spite of that, after only three minutes of search, there it was, still invisible to the naked eye and bound to hide behind the building 7 minutes later. Attached is a 50-frame animation made with images saved from a 4-minute video recorded with a Canon SX60 HS camera from 18:10 until 18:14 (GMT-3h). Also shown is the recorded track of Mercury exhibited with the Startrails program. As expected, the image shows significant scintillation effects caused by atmospheric turbulence, leading to apparent changes in brightness, color and even in the observed position of the planet.
