Lunar Occultation of Omicron Leonis — 17 March 2011

For Philippine observers, a star-moon eclipse will occur on March 17, 2011, from 6:20 pm to 7:10 pm (PHT). The event will be visible to the naked eye, but is best observed with a pair of binoculars, or with an astronomical telescope.

DETAILS (from AstronomyLive.com)

VISIBILITY: This will be the second time this year that OMICRON LEONIS or Subra will be occulted. This time it’s again visible in south-east Asia and the Phillipines but now also Australia and New Zealand can join the party! The star will disappear on the dark side, meaning easy to spot and very interesting to broadcast.

STAR & MOON: Omicron Leonis is a +3.5 magnitude star. The waxing Moon will be 92%, so there is some lunar disturbance. It all starts in Iba, the Phillipines at 10:50 Universal Time. Check the link below, to see when it starts and ends at your location.

LIVE BROADCASTING SCORE: Good. Although the Moon phase is not optimal, this occultation is beautiful to watch mainly because it disappears behind the dark side of the Moon. Another thing that makes broadcasting this occultation interesting is that the white line on the map – locations where the star will disappear and reappear behind the mountains on the lunar edge during darkness- is near the densely populated cities of south-east Australia. So when living near those white lines you should really find yourself a telescope and watch this occultation taking place.

HOW TO READ THE MAP BELOW?: The white line indicates that the occultation takes place during darkness. Blue is occultation at twilight and the dotted red line indicates occultation during daylight. Cyan means the occultation takes place when the Moon rises or sets. Another important feature of these maps is that you can check grazing locations (on the lines), places where the star will ‘scrape’ the Moon and thereby is occulted for a very short period of time.
