The story behind the greatest eclipse ever

I had to put it on mute, the narrator got on my nerves, but the video is very cool.

Hahaha. That was.....OMG......pornographic! Hahaha. Thank you for posting that. But I wonder if the eclipse would last much longer if the plane was flying along with the sun across the country and just how much longer would it last? Aren't there planes that can circle the earth in 24 hours?

Oh, and your link didn't work.

The shadow moves at ca. 3x speed of sound at its slowest (surface of the earth being perpendicular to the path of the shadow), 2600km/h for the 1999 eclipse if my calc is correct (see below) , the plane moves with 1x speed of sound. So, yes, you could elongate totality quite a bit by trying to follow the path of the shadow.

The shadow is 270km max (sometimes only 100km, like in 1999 over Europe, the one i witnessed). The difference in speed between Moon and plane would be 2600-1000=1600km/h 26km/min. It would take ca. 10 minutes for the Moons shadow to overtake a (subsonic) plane flying ahead. In 1999 it was less than 3 minutes on the ground. In 1999 three Concordes were flying ahead of the shadow at ca. 2200km/h, their eclipse lasted a whooping 15mins, but probably it was quite expensive. Smile

P.S.: His camera was overexposing the event by much. During totality and with the naked eye, you wont see such a massive glare.

RE: Solar Eclipse 2017
I found some great information on the NASA website and the question of whether one could follow an exlipse in a jet was answered! Thanks NASA!

On June 30, 1973, Concorde 001 intercepted the path of a solar eclipse over North Africa. Flying at Mach 2.05 the aircraft provided seven observers from France, Britain and the United States with 74 min of totality bounded by extended second (7 min) and third (12 min) contacts. The former permitted searches for time variations of much longer period than previously possible and the latter provided an opportunity for chromospheric observations of improved height resolution. The altitude, which varied between 16,200 and 17,700 m, freed the observations from the usual weather problems, and greatly reduced atmospheric absorption and sky noise in regions of the infrared.

Fantastic. 74 minutes! That would have been amazing.

Here's some more interesting stuff. The question is asked on the NASA website "How long will we continue to be able to see total eclipses of the sun?"

The orbit of the moon is not stable. Because of tidal friction, the orbit of the Moon is steadily growing larger, so that the angular size of the moon from the Earth is shrinking. The moon's orbit is increasing by about 3.8 cm (1.5 inches) per year. When the moon's mean distance from Earth has increased an additional 14,600 miles, it will be too far away to completely cover the sun. This is true even at perigee when its disk will be smaller than the sun's disk even when the sun is farthest from Earth at aphelion. At the current rate that the moon's orbit is increasing, it will take over 600 million years for the last total solar eclipse to occur. A complicating factor is that the size of the sun itself will grow slightly during this time as it evolves as a star, which will act to make the time of "no more total eclipses" a bit sooner than 600 million years.

Hummm, I think this is interesting because religious nuts are always trying to claim proof of god is the perfect alignment of the earth and sun which makes a total eclipse. Welp, this will someday be going to go away.

Here's the NASA eclipse website.

Total darkness will pass over my house, so I ain't plannin on leavin the house, neither. It could be overcast, or even raining here, tho. So I'm half tempted to strip down to my undies, grab up a hatchet, a garden hoe, and a make shift feather headdress, and medicine man chase the rain away with my recently perfected Wurzagg Da Great Green Prophet Dance!

Safest way to look at it! Also, isn't technology amazing?

So.......... they are streaming my screen slowly getting dark? I could accomplish that right now with the brightness control.

I already keep my brightness low. It'll be amazing.

RE: Solar eclipse will be livestreamed
I feel like I should be more impressed about this but it's just something that happens...I can't seem to drum up any excitement about it.

Maybe if I thought it was some sort of sign. Consider

Honestly, Anj, I imagine if I were a primitive peasant..... or a republicunt fuckhead, I would probably shit my pants when the sun vanished.


But I'm not.
