Solar Eclipse

http://sunearth.gsfc.nasa.gov/eclipse/S … 05.html]Is called a "Hybrid" Solar Eclipse

*Maybe I've been in a coma all these years, because I don't recall ever reading/hearing of a solar eclipse referred to with the word "hybrid" attached to it. :-\

On Friday, 2005 April 08, a hybrid1 eclipse of the Sun will be visible from within a narrow corridor which traverses the far Southern Hemisphere. The path of the Moon's shadow begins southeast of New Zealand and stretches across the Pacific Ocean to Panama, Colombia and Venezuela. A partial eclipse will be seen within the much broader path of the Moon's penumbral shadow, which includes New Zealand, much of the South Pacific, South and North America.

-*-

A hybrid eclipse is a unique type of central eclipse where parts of the path are annular while other parts are total.

Have known of that, of course (partial annular -- partial total).

In most cases (like in 2005), the hybrid eclipse begins annular, changes to total for the central portion of the path, and then converts back to annular towards the end of the path. However, some hybrid eclipses may be annular only at the beginning (e.g. - 2013 Nov 03) or at the end (e.g. - 2386 Apr 29) of the path.

Maybe I lived in an agricultural area for so long that the word "hybrid" seems weird when applied to an astronomy event.

*Nice. Guess I'll see a portion of eclipse, even if slight.

*Treasure hunting?

But there is something to see: the shadows.
Look under a tree. Sunlight beaming through gaps in the leaves make crescent-shaped spots on the ground. Look around the walls of your home or office. You might see crescents projected by slits in the window shades. Windows with cut glass are even better. Their prism-sharp corners bend sunlight and cast rainbow-colored crescents in unexpected places. It's like a treasure hunt.

Then this:

You can make your own crescents. Lay your left hand on top of your right hand, criss-crossing your fingers waffle-style; hold your hands so that sunlight can beam through the gaps. You'll see a pretty matrix of crescents on the ground. Have you ever made a turkey or a rabbit using hand-shadows? Try it during a partial eclipse; the animal's eye will be crescent-shaped.

Nifty. I doubt there'll be enough of a crescent over my area, but if so...I'll give these suggestions a whirl.

*Spaceweather.com has just now re-posted a gallery of photos from the partial eclipse of 10 June 2002 (I remember it well, and observed it), which shows some of the visual phenomena described in the article:

Crescent-shaped sunbeams will dapple the ground during Friday's solar eclipse

Look out for them; I will.

*I've carried over the motion map from a previous post. Folks in my region won't see much of an eclipse.

This eclipse will be total for folks in the remote South Pacific, and annular near New Zealand and parts of South America.

::EDIT:: I suppose most people here know this already, but just in case:

Extreme care must be taken when looking at the Sun. There are a number of ways to Safely View the Eclipse which you should consider. NEVER LOOK DIRECTLY AT THE SUN WITH THE NAKED EYE OR THROUGH ANY OPTICAL DEVICE (e.g. - camera, binoculars or telescope).

*A bit of info from a new space.com article pertaining to the aspect of today's (hybrid) eclipse, regarding where it'll be seen as total for a very few folks:

It’s not likely that many people will see the total phase of Friday's solar eclipse. Totality will be visible only from the middle of the South Pacific Ocean and only for, at the very most, 42 seconds.
Only from an aircraft or the deck of a ship positioned precisely within the very narrow (17-mile-wide) path of totality would observers get a brief glimpse of a completely obscured Sun, one of nature’s great spectacles.

I'd like to see a total eclipse and an annular eclipse. Haven't had those privileges yet. :-\

Weather clear here today, and I'll catch what I can of today's event.

--Cindy

P.S.: Additional general info:

It is a popular misconception that the phenomenon of a total eclipse of the Sun is a rare occurrence. Quite the contrary, about once every 18 months, on average, a total solar eclipse is visible from some place on the Earth’s surface. That’s two totalities for every three years.

*Spaceweather.com is hosting a gallery of images regarding yesterday's event. This gallery will be continually updated as new images are submitted.

We saw a partial eclipse yesterday. Set up the sunscreen on my telescope, during the maximum of the eclipse for our time zone. My husband and I watched it for a while.

The event as we saw it looks exactly like Mr. David Marshall's photo from Barbados. Just a bit of a bite out of the Sun. :;):

*Someone managed it! :band:

http://www.spaceweather.com/eclipses/08 … ana1.jpg]A photo from the path of totality -- Dennis Mammana.

Amazing. And the clouds cooperated, too.

Here's the caption which went with the photo (this is all hosted at spaceweather.com):

It was around noon local time that the moon's shadow overtook the M/S Paul Gauguin in the South Pacific Ocean, where 266 total solar eclipse chasers were waiting with great anticipation. And, because of the expert navigation of Captain Gilles Bossard, the sun popped out from behind a huge cumulus cloud only seconds before totality; such dramatic timing would have been envied by any great Hollywood director! Location: Approximately 128 W Longitude, 21 S Latitude

I love it when people get that rare, "against the odds" photo of astronomy events.

*Yet another attempt to photograph the eclipse from an ocean ship:

http://www.spaceweather.com/eclipses/08 … .jpg]Click

That's from Mr. Craig Prater, who was aboard a cruise ship at the time. He said:

These images were taken 1 second apart using a Canon Digital Rebel at ~200 mm focal length on a fixed tripod. The rocking motion of the ship caused the center of the image to bob up and down from exposure to exposure. So you can really appreciate any high mag telescopic images taken under these conditions!

Teehee. What the heck; he managed it! Cool. :up:

His photo and quote are hosted by spaceweather.com. Looks like the sky is riddled with bullet holes in that pic.

*Total for some (few), Annular for others. Nice comparison.

Another comparison:

How rare is such a hybrid eclipse? Calculations show that during the 21st century just 3.1% (7 out of 224) of solar eclipses are hybrid while hybrids comprise about 5% of all solar eclipses over the period 2,000 BC to AD 4,000.

Well, I thoroughly enjoyed this whole page of your posts, Cindy. Not just great pictures but I learned something about annular eclipses, too!. Thank you.
