'Extreme Supermoon' Will Come Dangerously Close To Earth On March 19

Capture an image of the Extreme Supermoon near the horizon. Special rule: The earth's horizon must be part of the scene. Advanced editing. Image submission time window must include March 19, 2011.

Still looking for the answer, which seems to be not available. "The supermoon on March 19th will see the orb pass within just 221,567 miles of the earth, the closest it has been since 1992." The only statement I've found on apparent size is "...much larger." I'll continue to search.

Not much. It's a difference of one or two kilometers out of about 359,000.

Oh good grief, "dangerously close" my ass. It's simply a perigee full moon. See here. Happens every 14 months. This one may be just *marginally* closer than a normal perigee full moon, but don't expect anything that you wouldn't normally see every year or so.

ETA: I see Shannon beat me to it. Yep, a tiny margin compared to the total distance.

Perigee vs. Apogee
March 19, 2011 will be 356,000 km.

Not a lunar-tic, am I. I agree with the comments above, if "marginally closer" means something like seeing London on the horizon from downtown New York. (just tongue-in-cheek fun with perceived distance and size.)

"the change in the apparent diameter can be up to 14% between apogee and perigee"

I'll be photographing the moon near the horizon on March 19.

i have always found photographing the moon difficult, if i take a long exposure to try get some of the landscape the moon in blown out, but if i do a shorter exposure, the image is way too dark.

I had a play around shooting the moon last year - this was a very short exposure, 1/3200th, tripod mounted
- I found that the image was soft with anything shorter than 1/1000th.

There are always windows of opportunity which allow enough twilight light to capture the moon properly against the sky showing the edge of the shadow of the earth. This allows a fast enough shutter speed to "freeze" the moon.

It would be a great time for a Day Taken At Night challenge :)

It's much easier to just do a double exposure, and make it pretty obvious that the moon is oversized. Maybe a special rule bend to allow double exposures would be right for that sort of challenge.
Here's another, this one single exposure. Sometimes you can get the haze at the horizon to work nicely with a moon shot.

It's just a matter of having a longer lens Waddy!

Break out with a 400mm + 1.6x crop, and you can pull off stuff like this shot...

Note that the moon seems to move VERY fast when it's near the horizon, so snap quickly.

Or a special rule to require double exposure. Get those creative juices flowing.

At least this isn't as bad as the Mars Hoax.

Here are some of shots from what NASA was heralding as the "Super Harvest Moon" at the last Autumnal Equinox:

Totally misread this as Extreme SUPERMOM near Earth.

Supermom, Supermum, or strange moon - this thread lead me back to some
very early (ahem) digital files to find...

for some reason, I can't seem to find the date this came into being.

Did someone just turn into a rabbit? Anyone? Maybe I have to wait till the 19th to chant it ...

I greatly fear what slippys entry might be for this challenge. Or for that matter Leroys. But if Leroy doesn't use cheese his might be very nice. (No SPs please!)
