Supermoon!

Post by Christopher K. »

Supermoon is an event where the Full Moon occurs very close to perigee. These can be up to 14% bigger and 30% brighter than apogee Full Moons. Happily, it seems most fears that the tidal forces of the Moon caused the horrible earthquake off the Japanese coast are being eradicated.

Full Moon is at 1:11pm CDT today, and the Moon rises here in Baton Rouge at 7:33pm CDT. It will be in the constellation Virgo, about twelve to thirteen degrees to the upper right of Saturn. A view of the rising Moon against background trees may show whether the classic illusion of it appearing bigger near the horizon is amplified by its actual nearness. Some psychologists think this a variation of the Ebbinghaus illusion, during which we perceive the size of an object to be different based on its surroundings. A nice interactive example of the Ebbinghaus illusion is at...

I know Im a little late here, but I actually went out that night and took a few pics of the Supermoon. Sorry, it's not the best, I don't dabble much in photography---

Well, another Supermoon (or perigee Moon) is near. Full Moon and perigee are both between 10:30pm and 11pm Central Daylight Time Saturday night--in fact, one minute apart. Tides worldwide are not expected to be any more dangerous than usual.

Friday's APOD was a Sun-Supermoon comparison.

I was slightly surprised at the amount of media coverage the event received. It was cloudy over HRPO a vast majority of the night. Ben was operating; he gave a tour and then closed upstairs. Fifteen minutes before we were to close, the clouds parted. Ben rolled out the 10" Orion and was able to show the die-hards which had stayed the Supermoon! It being full, we didn't have any glorious shadows to investigate, but I think we pointed out Aristarchus and Tycho.

And here we go again! A Supermoon will occur at 6:32am CDT tomorrow morning. At that time it will have just gone below the Baton Rouge horizon. Most people's best chance is to go to HRPO during standard viewing time tonight, from 7:30pm to 10pm. Of course, ARRL Field Day is in progress and the public is allowed to participate in that as well until 10pm.

Saturday's APOD is from Anthony Ayiomamitis, and shows last year's Supermoon over Cape Sounion. Also in the image is the Temple of Poseidon, ca. 444 BC, which some believe may have been created by the same designer (name lost to history) responsible for the Hephaisteion.

Apparently, we in the astronomy communities are now taking to call the smallest Full Moon of a year the Micro Moon! This year's Micro Moon was on 15 January.

The 21 January APOD shows a superimposed comparison of Micro over Super...

The 10 August Supermoon was captured in rising sequence, coming out from behind Castle Fylla on Evia. Anthony Ayiomamitis is responsible for the good work, which appears on page 73 of the November Astronomy.

He used a four-inch Takahashi refractor.

Sunday's Full Moon is a Supermoon, which makes the total lunar eclipse on that day even more special. Since the beginning of the twentieth century, there have been only five Supermoon Total Lunar Eclipses--in 1910, 1928, 1946, 1964 and 1982. Are you old enough to remember the songs that played on the radio in 1982, or 1964?

The next Supermoon Total Lunar Eclipse will be in 2033.

Monday's Full Moon is a Supermoon and is it already making headines! This will be the closest Full Moon since 1948.

There are several ways to find out more information about this event. From 5am to 10:30am CST tomorrow on NASA-TV3, several live windows will be open to scientists explain the distinction of the Supermoon and how the Lunar Reconnaissance Orbiter has changed the way we know the Moon's surface. Also, tomorrow at HRPO's Edge of Night event from 4:45pm to 6:45pm CST personnel will discuss the Supermoon at length (including the famous illusion wherein the Moon seems larger at the horizon).

Coincidentally, Monday night is also the Baton Rouge Astronomical Society's 35th Anniversary Party! The party runs at HRPO from 7pm to 9pm CST, has no admission and is open to the public.
