Hi WildMoon!
Please be patient! :D
You must wait til 2012 May 20 and 2014 October 23 to witness partial eclipses in Houston!!! :(
But if you sit down calmly and rest, you will see a better eclipse on 2017 August 21. :)
Then I hope you will see a TOTAL one in 2023 October 14!!! 8) 8) 8)

Here in Italy, my hope is to see tomorrow's eclipse: in fact weater forecast is ugly :x
Then the next one for us will be next March! :)

Bye bye
Pierluigi

And some 83-84% here in the Algarve. I'm not sure if I'm going to be able to watch the eclipse, though, since at the time of its maximum I'm usually on the road. I may have to get late to work, but since it's probably going to be the largest eclipse I'll ever see I may do just that.

While annular solar eclipses with 80-90% sound impressive,
my personal experience has been somewhat disappointing
after having observed several such annular eclipses already.

Clearly, with a telescope (having a Mylar foil in front!) it
looks great to watch the shadow moving in at high
magnification.

But the hard-to-describe amazing natural phenomena just
before a TOTAL eclipse are all lacking, unfortunately. The
sun is so bright that even a 80-90% coverage will not
darken the environment noticably. Correspondingly the
striking reactions of animals (birds etc...) are entirely
lacking along with this incredible twighlight, the racing-in
shadow, the famous "diamond"-ring effect, the visibility of
the corona etc...

Probably it's going to be bad weather in Hamburg
anyway...

The animals don't act as if to say "AAAAAAAAHHHHHH!!!!! WE'RE ALL GONNA DIE!!! I LOVE YOU HONEY!!! Hey, are those pancakes? Yum! Oh, right. AAAAAAAAAAAHHHHH!!!! WE GONNA DIE!!!!"?

Man, that sucks! :evil:


This means I'll have to conduct my evil plan to move the moon so that Houston'll see lots of eclipses and move the moon closer to Earth. :twisted: Might as well conduct my evil plan to stick a bunch of other moons in orbit of Earth and put a ring around Earth. :twisted: Muahahahahahaha!!! Oh wait, did I say that in public? Oopsy... :oops:

Well, it was pretty neat. Light dimmed quite a lot, temperature also chilled noticeably, and one or two birds even decided to emit an interrogative peep as if asking "what the heck?!"

The sun was reduced to a thin arc around here. It was a lot more intense than the largest eclipse I had seen before, in which about 60% of the sun's disc went black. Even so, it was pretty bright, considering. According to a little math I made, and I ask if anyone can kindly confirm (or not), the apparent magnitude of the Sun covered by 84% goes up a mere 1.9897, thus becoming -24.74. That's as bright as it looks at about 2.5 AU. Super.

A partial eclipse does never even nearly show the impression that a total eclipse does. In fact, even until the very last moment it stays rather bright - about like a very cloudy and stormy afternoon. If the sky is cloud covered during eclipse, you couldn't tell if it's the eclipse, or a thunderstorm approaching.

In the very last moments you see the sun crescent melt, until a single bright drop remains, which then disappears. And only AFTER that, light vanishes as if someone dims it down with a fader control. Within about 5 sec it becomes black night, while the horizon is shining in bright sunlight. It's creepy.

I photographed the eclipse projected on the ground by trees in Barcelona, where it was partial but the crescent got fairly thin. You can see a picture here:

Most people on the street probably had no idea anything unusual was happening. The light got noticeably dimmer and cooler to the skin, which made it a nice time for a walk.

I just love that effect. Thanks for the picture, Matt.
