    @magicpanda

    No idea. Just saw it linked in the comments but had doubts. Guess that's sandy dunes rather than snowy hills in the backdrop.

    @oldschoolsoviet Cool vid though. It's been doing that for 40 years.

    The sky apparently clear tonight around here, so I'm currently planning on carting my scope out to the middle of a field and see if I can catch DA14! Woo.

    Probably won't see anything, of course. But even the prospect of not having clouds is quite exciting tbh.

    If experienced the sonic boom those Russians had, I would shit my pants.
    Would it be hard to track with a telescope? It'll be moving pretty fast, I'm thinking I might be better off using binoculars.

    Yeah, I really wished I had a low power 2" eyepiece, or some kind of ultra-wide thing. The best I've got is a 32mm plossl. My plan is to aim my dob at Ursa Major when it's due to cross it at 2130 or so and hope!

    I'll take my bins as well, but I find using bins difficult because I wear glasses. Also, the predicted magnitude is 8 to 11 for the UK, so it's going to be bit of a push for bins imho, though that does technically put it at what you should be able to see with bins.

    Why does every car in Russia seem to have a video camera on the dashboard? Just about every crazy car crash clip is Russian.

    If I saw that coming down I would completely shit myself. Having said that I saw a big fireball shooting over our flat once (we lived in the roof, Velux windows), and just jumped out of my seat whooping, the gf thought I was having some sort of fit....
    This is why.

    It stole DA14's thunder, hell of a move.

    I doubt it'll be the last somehow. DA14 is probably travelling with an entourage of small asteroids but while that sounds scary, our atmosphere is probably more than up to the task. I hadn't thought about the sonic booms before, pretty crazy.

    What kind of damage would something that size do if it hit? Say it hit Scotland.

    No one would notice if it did land in Scotland. It'll die of liver failure in 30 years after a short life of heavy drinking and knife crime.

    It'll cause millions of pounds worth of improvements.

    Donald Trump would try to turn it into a golf course.

    The world is going mad. Me? I'm doing fine.

    Seriously though how much damage. Big enough to wipe out a city?

    Are you talking about DA14, or the thing that hit Russia? The Russian thing managed to take out a chunk of a factory. If DA14 hit, yeah it'd take a city out at a guess.

    My 10000 Km wide asteroid made of iron may have melted Earth but at least the day cycle is only 4.17 minutes different.

    I think that everyone should be ok with that.
  • Deleted user 15 February 2013 19:49:40
    4.17 minutes different which way? I don't want to have to get up any earlier.

    Yeah it'd wipe out a city if it hit. The damage would be localised, it's "only" 50m across, the ones that have fucked this planet up properly a measured in terms of miles not meters. Chicxulub asteroid was 6 miles in diameter, for example. DA14 would likely break up as it entered the atmosphere, it would cause millions of deaths if it hit a city but the damage would mostly remain local to that area.
  • Deleted user 15 February 2013 19:51:01
    Oh, I changed it's speed and now the day cycle is 26600000 hours out.

    A lot of people are going to be very late for work that day.
  • Deleted user 15 February 2013 19:51:23
    So what you're saying is that it's going to hit Birmingham.
  • Deleted user 15 February 2013 19:53:48
    You know what I find amusing about this Russian meteor business? A week or so ago, I took an intro class to Natural Disasters, and the lecturer said about how injuries from meteor impacts are non-existent and always apocryphal in nature, and that wouldn't change anytime soon.

    I thought it was human deaths from meteors.

    Anyway, anyone seen the big fella yet?
  • Deleted user 15 February 2013 19:59:39
    There have been zero recorded human deaths and something like one actual recorded injury, which was just a light bruising. Or so the textbook claimed.

    The injuries weren't a direct result, broken glass was. In a way he's right, but you can argue the opposite now.

    I dropped the class anyway, for it was shit and took up too much of my evenings. Stupid evening classes.

    So being injured by a meteor is actually only being hit directly with the rock?

    If people are still wondering what would have happened if it hit us:

    A much larger meteor hit Earth in 1908

    If it hit a large city, then it would have flattened it, but Earth as a whole wouldn't have been in danger.

    My sky was clouded over in the end. Ho-hum. British weather, don't you love it.
