DHAKA: The next supermoon is coming up on Sunday. It’ll be the closest, brightest supermoon of this year. It also presents the moon’s closest encounter with Earth for all of 2014.

Full moon falls on  the day at 18:09 UTC (1:09 p.m. CDT in the U.S.). The moon will not be so close again until the full moon of September 28, 2015. In other words, it’s not just a supermoon. It’s the closest supermoon of 2014.

At United States’ time zones, the moon will turn full on August 10 at 2:09 p.m. EDT, 1:09 p.m. CDT, 12:09 p.m. MDT and 11:09 a.m. PDT.

We astronomers call this sort of close full moon a perigee full moon. The word perigee describes the moon’s closest point to Earth for a given month. Three years ago, when the closest and largest full moon fell on March 19, 2011, many used the term supermoon, which we’d never heard before. In the following years, we heard this term again to describe the year’s closest full moon on May 6, 2012, and again on June 23, 2013. Now the term supermoon is being used a lot. Last month’s full moon – on June 13, 2014 – was also a supermoon. But the August full moon is even more super! In other words, the time of full moon falls even closer to the time of perigee, the moon’s closest point to Earth. The crest of the moon’s full phase in August 10, and perigee, fall within the same hour.
