This weekend will be the biggest and brightest moon of 2013, and we want to see your photos!!
On 23 June 2013, a Supermoon will be occurring, NASA says. What that means is that the Moon will be closer to the Earth than at any other time during the year – in fact, the upcoming Supermoon will be the closest encounter between the Earth and the Moon until August 2014. And what better place to see the Supermoon than on the water?
The Moon will reach its closest distance to the Earth at exactly 7:32 am EDT on 23 June, but because it will be peaking in the early morning hours, both 22 June and 23 June will put on similar shows, according to NASA. So either day will be a good opportunity to see and snap photos of the larger-and-brighter-than-normal Supermoon.
NASA estimates that this year’s Supermoon will be up to 14% larger and 30% brighter than a typical Full Moon is. This is a result of the Moon reaching its perigree – the closest that it gets to the Earth during the course of its orbit. During perigree on 23 June the Moon will be “only” about 221,824 miles away, as compared to the 252,581 miles away that it is at its furthest distance from the Earth (apogee). The Moon will actually be at apogee only two weeks after the Supermoon, on 7 July.
How to Enter
Just send us your photos and a little background about the photo (location, camera, etc) by emailing [email protected] with the subject “Supermoon”.
Best photos will be chosen for the site next week, making you instantly famous. After that, the best of the best will be chosen by an esteemed panel of judges and the winner will receive a $50 gift card.
Rules: To be considered for the site, the photo must be taken from a ship, of a ship, or in some how/way/shape/form maritime related. Submit photos by Monday June 24, 2013.
More from NASA on the so-called Supermoon:
What is the definition of a Supermoon and why is it called that?
‘Supermoon’ is a situation when the moon is slightly closer to Earth in its orbit than on average, and this effect is most noticeable when it occurs at the same time as a full moon. So, the moon may seem bigger although the difference in its distance from Earth is only a few percent at such times.
It is called a Supermoon because this is a very noticeable alignment that at first glance would seem to have an effect. The ‘super’ in Supermoon is really just the appearance of being closer, but unless we were measuring the Earth-Moon distance by laser rangefinders (as we do to track the LRO [Lunar Reconnaissance Orbiter] spacecraft in low lunar orbit and to watch the Earth-Moon distance over years), there is really no difference. The supermoon really attests to the wonderful new wealth of data NASA’s LRO mission has returned for the Moon, making several key science questions about our nearest neighbor all the more important.
Are there any adverse effects on Earth because of the close proximity of the moon?
The effects on Earth from a supermoon are minor, and according to the most detailed studies by terrestrial seismologists and volcanologists, the combination of the moon being at its closest to Earth in its orbit, and being in its ‘full moon’ configuration (relative to the Earth and sun), should not affect the internal energy balance of the Earth since there are lunar tides every day. The Earth has stored a tremendous amount of internal energy within its thin outer shell or crust, and the small differences in the tidal forces exerted by the moon (and sun) are not enough to fundamentally overcome the much larger forces within the planet due to convection (and other aspects of the internal energy balance that drives plate tectonics). Nonetheless, these supermoon times remind us of the effect of our ‘Africa-sized’ nearest neighbor on our lives, affecting ocean tides and contributing to many cultural aspects of our lives (as a visible aspect of how our planet is part of the solar system and space).
