LOS ANGELES (LALATE) – The Supermoon full moon tonight June 23, 2013 returns with a Perigee peak hour tonight. When is the peak hour for Perigee Supermoon full moon tonight 2013, and how do you watch it? Officials tell news that the Supermoon full moon will reach its peak hours in the United States on June 23 at 7:32 a.m. EDT. This evening marks the closest approach of the moon to the Earth for the year 2013. And while tonight marks its annual approach, it’s not as history as the Supermoon reported on LALATE two years ago.
The Supermoon full moon fascination is actually only two years old. In fact, as NASA explains to news, until 2011, the annual spectacle was only called a “perigee full moon”. It would come and go each year with news reports simply referring to it only as the “perigee full moon” and nothing more.
Perigee moons are substantially larger and brighter than moons that happen on the apogee side. Perigree moons are also bigger than your average full moon. In a statement to news in 2011, NASA explained that “It is an ellipse with one side (perigee) about 50,000 km closer to Earth than the other (apogee): diagram.” NASA added that “Nearby perigee moons are about 14% bigger and 30% brighter than lesser moons that occur on the apogee side of the Moon’s orbit.”
But all this changed on March 19, 2011. As reported on LALATE at the time, U.S. news began to use the term “Supermoon” for the first time to described the annual Perigee Moon. The reason was that the 2011 Perigree Moon was the largest and closest to Earth since 1993.
Since then, the annual Perigee spectacle is now being dubbed each year a “Supermoon”. Ironically, NASA tells news that last month’s full moon was also a Supermoon. But tonight’s real Perigee “Supermoon” is even larger that the non Perigee Supermoon last month. Just don’t expect it to be as impressive as the one you saw in 2011.
So where does the word confusion leave us? NASA tells news that there is only one Perigee Supermoon per year. But there are lots of non Perigree Supermoons per year. In fact, there are four to six this year alone.
Moreover, the annual Perigee Supermoon is hard to calendar. It doesn’t arrive the same time each year. Next year, it will happen on August 10. In 2015 it’s September 28, followed by November 14 the year after. Another impact by the Perigree Supermoon is high tides. Those will continue for the next full days.
But when is the peak time tonight? Officials tell news that the best time is Sunday June 23 at 7:32 a.m. EDT, 6:32 a.m. CDT, 5:32 a.m. MDT and 4:32 a.m. PDT. And yet, there is nothing in tonight’s Supermoon that should prompt alarm to residents. NASA tells news that the Earth already has enough “internal energy”, and that this closer position in its orbit tonight won’t impact anything substantial.
