You can try http://spaceflight.nasa.gov/realdat...P/JavaSSOP.html The SkySearch tab lets you put in your location and then search for possible sightings for any date, past or future.

Deteriorata posted:You can try http://spaceflight.nasa.gov/realdat...P/JavaSSOP.html Yeah I have SkyFree installed on my phone, it's an iOS Augmented Reality stargazing app, and when I put it up to the sky, the ISS was down at the horizon, and the only thing that was in view was a Saturn-V stage floating around there and I seriously doubt it was that.

Lazlo Nibble posted:SkySafari Pro has an enormous satellite database; if it's visible from the ground it's in there. If you don't want to drop the forty bucks, I can check it for you—just give me the exact date and time and as good a description of the path as you can. Hmmm. I mean, it was either Thursday or Friday, 28th or 1st. Just before sunset, so probably between 5:00-6:00PM EST. In my compass app here's my guess as to where it was: Facing: 118* SE 40*49'10" N, 73*57'0" W It's path was one that had to have gone directly overhead, in that direction.

That was definitely the ISS then. Just before 5:30 PM Thursday. It moves fast enough it could easily have dropped to the horizon in the time between when you spotted it and when you had SkyFree fired up.

AWESOME, I'm most definitely going to get Sputnik! then, because now I know exactly what to look for! That's so incredible.

Also http://www.heavens-above.com/ Pretty nifty sites, especially for keeping an eye on Iridium flares. And for real - catching a major Iridium flare is an incredible experience. Like a flash of a laser that travels across the sky.

There's a Horizon special about Meteors on BBC 2 at 23:20 tonight. Hopefully it's not too dumbed down with 80's pop music and CGI.

As much as I love getting alerts on my phone for ISS passes and Iridium flares, nothing beats spotting a satellite on your own and figuring out what it is. I was outside last April to watch a really right Iridium flare, and after a few minutes of looking up I spotted a dim pulsing reddish spot moving across the sky. After checking cataloged satellites, I concluded that it must have been Envisat but it appeared to be slowly tumbling. A day or two later, ESA announced that they had lost contact with it.redshirt posted:Also http://www.heavens-above.com/

There was also a documentary about this incident on channel 4. Meteor Strike: Fireball from Space. I don't know if this is the same as the one you have mentioned. It seems you can watch it online on channel4 but unfortunately not in my country.

evensevenone posted:Finally, when it does explode (and it was a decent-sized explosion), there wouldn't be any nuclear radiation. Again, there are space and ground based detectors for the type of radiation produced by nuclear detonations and it's super-obvious when there is an aboveground nuclear event (underground tests are harder). What if the meteor happened to have a vein of uranium in it?

Charlz Guybon posted:What if the meteor happened to have a vein of uranium in it? Naturally occurring uranium doesn't go off in nuclear explosions. You need a large dense mass of purified Uranium-235, and the ore is crumbly stuff mostly containing Uranium-238. I don't think a meteor could have uranium anyway, they tend to be made of lighter and more abundant elements like iron and nickel.

Natural uranium vanes have reached critical mass, but as they are not pure enough for fusion they just warm up.

Generally yes, but there may be fringe cases of uranium planets that reached critical mass + went off in nuclear explosions, sending uranium meteors across the cosmos.

and I seriously doubt it was that.
