    Apparently not. But it just seems so impolite for you not to get at least one reply to your thread; so here you go I may even get up and see if I can see it.

    Was the title of the thread a reference to Day of the triffids?

    If not you missed a good one there.

    Also there's some sort of eclipse tonight


    this is interesting:

    Later this year . . .

    On July 22, the longest total solar eclipse in the 21st century will take place, as the moon's dark umbral shadow races across central India, the People's Republic of China (including Shanghai), and some of the Ryukyu Islands of Japan. At the point of greatest eclipse, totality will last 6 minutes 39 seconds; the longest of any eclipse between 1991 and 2132; it is an eclipse that is eagerly being awaited by millions who live along the path of totality and countless thousands more from around the world who plan to position themselves within the path.

    Is it powered by biofuel or hydrogen?

    I didn't know comets could be green coloured. That's interesting.

    I'm not sure if we'll be able to see this... it says it'll be visible about 3am. I'm assuming NASA operates on ET (Eastern Time) which is 5 hours earlier than GMT? So that'll be 8am here which I'm guessing is too late to see a comet.

    I'm not too clued up about viewing comets though, maybe we will be able to see it!

    No, we'll be able to see it at 3am our time, due to the earth's rotation.

    are you sure about that, yeah?


    it also says
    Current estimates peg the maximum brightness at 4th or 5th magnitude, which means dark country skies would be required to see it.
    does that mean that everyone in the city isn't gonna be able to see it?

    Erm really? In 5 hours a comet can travel quite a distance.

    My understanding is it can only really be seen from the countryside. At that brightness I'd have thought that moving the comet 5 hours away would render it almost impossible to see.
