Supermoon is a term that describes a full moon occurring at a time when the moon is at its closest distance from Earth. The full moon of May 6, 2012 is the largest full moon of the year.

This month’s full moon is the largest full moon of the year! :)
There is much confusion on the Internet as to what time this “Super Moon” thing would occur. According to a lunar calculator from the NASA website, the “Full Moon” should occur on May 6, 3:36 am Universal Time, this Sunday. In local time (Philippines), there would be an additional 8 hours due to the differences in time zones, thus, in the Philippines, the precise moment will occur at “2012 May 6 3:36 UT” + “8 hours” = 11:36 am May 6 (near noontime). Unfortunately, 11:30 am is a daytime here in the Philippines, thus, the moon will not be visible. To be able to observe it, either you observe tonight, just a few hours before sunrise, or later tomorrow, a few hours right after sunset.
To calculate for your local time, just add or subtract the correct time difference. In the given example, I used +8. Just substitute it and do the math :) Hope it answers some of the confusion.
Crater Clavius has a diameter of 225 km, roughly the same distance from Manila to Baguio (250 km). Taken on March 6, 2012 with a 4-inch f/9 refractor with 2x barlow and an SPC900NC web camera. More lunar crater images here.
