Lunar Occultation of Jupiter – August 12, 2012
During the early morning hours of August 12, Philippine sky observers had a great chance of witnessing a relatively rare occultation of Jupiter (and some of its largest satellites) by our Moon. In astronomy, an occultation is an event that occurs when an apparently larger body passes in front of an apparently smaller one. In this case, the moon passed in front of the planet Jupiter; the pair being visible in the morning sky in the Philippines about 5 hours and 53 minutes before the Sun. At the moment of closest approach, the Moon was at mag -11.3, and Jupiter at mag -2.2, both in the constellation Taurus.
Despite the presence of hazy skies and thin clouds, we were lucky to have been able to observed the occultation event. Once I located the moon with my naked eye, I immediately pointed my superzoom camera to it and took an image. I found Jupiter close to the moon but it was covered with haze. A few minutes later, Jupiter slipped behind the bright lunar limb and was visible no longer. Half an hour later, I tried to capture a video of the reappearance of Jupiter, but the clouds had thickened to the point where I could no longer find the moon. When the clouds had finally gone out of sight, Jupiter was already emerging from behind the dark limb.
Still, considering the less-than-ideal conditions, it was quite a successful observation. 🙂
Sky condition: 70-80% cloudy
Camera used: Canon Powershot SX40 HS
I observed this event from Marikina City.
