tomorrow ie friday 15th feb 2013, a 65m rock is going to wizz past us at a height of 0.09 lunar distance, hopefully some very apt photographers get a chance to take photo of this. I believe it is the closest any cosmic object has passed the earth....nothing to worry about, theyve been tracking it for months.....soothsayers put your placards of doom away....it aint gonna hit...I think[bigwhistle]

Are you sure of that distance (is it not 0.09 Astronomical Distance?) - that is only about 20,000 miles so I would expect it to go into orbit round the earth and eventually crash.

I will be watching for it.

Near Earth Asteroids






Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.





On February 14, 2013 there were 1381 potentially hazardous asteroids.

Any idea of a time?

NASA is doing live streaming at 2pm eastern US time, by my best reckoning that should be around 6am eastern Oz time, Saturday 15th.

NASA - NASA to Chronicle Close Earth Flyby of Asteroid (http://www.nasa.gov/home/hqnews/2013/feb/HQ_M13-031_Asteroid_Flyby_Coverage.html)

BTW this all took a couple of minutes to find on Google, including the time zone calculator.:):):)

here you go, this has my home gps co ordinates,

Asteroid 2012 DA14 Flyby (http://www.heavens-above.com/2012da14.aspx?lat=-37.67947&lng=145.50568&loc=healesville&alt=150&tz=AEST)

at +7.4 mag I would not bother getting your camera out,

(the lower number the brighter)

Interestingly the rock is passing at only 34,000 klm high , as noted inside the ring of geo-stationary satellites, hope it dosen't hit a damn Inmarsat bird, I'm going to be relying on my satphone a bit over the next 12 months.

I often use the Heavens Above website to predict location & time of iridium flares to photograph, if they are -3 or brighter I'll set up my tripod , moonlight / clouds permitting

btw the image below shows a -3.5 magitude iridium flare, I've shot the ISS before at -1.0 mag and you can hardly pick up a faint line , so other than wearing a hard hat I would not get too excited about the +7 asteroid.

Its going to happen at approx 0930 saturday...my apologies for saying friday before , I thought it had been time/date adjusted. closest proximity is going to be over Indonesia and will be tracked by Australian observatories. you can follow a simulated update here .....refreshed every two minutes

So , it's no use looking north at 0930 hrs tomorrow morning coz we won't be able to observe it with the naked eye it even if it were in visible range?

if you go to my link you can observe it simulated from several different approaches or follow the links to NASA's live tv where you may get live pictures from australia's deep space tracking facilities....which is what NASA is using anyway.

yes, easily seen from Eltham (or Wandin) if it was visible. (if you could find a dark enough spot (sugarloaf) and the moon wasnt out you might see it with binoculars)

At Healesville it will come into view (if you could see it) at 36.9 degrees elevation (above the horizon) at 23.30 tonight and looking 173 degrees (approx South) will reach max elev of 46.1 degrees, and will dissapear from view at 0630 tomorrow morning , at 318 deg (north west) 11.2 deg above horizon. Eltham will only be a few degrees off.

so it will be very slow moving, you will hardly see it moving at all so will be very difficult to pick out.

Well, something just hit Russia. Seems like DA14 had some unseen mates travelling with it.


A meteor shower has caused explosions in the lower atmosphere above central Russia and the Urals region, blowing out windows and causing injuries.

‘‘There was a meteor shower, without fragments falling to the ground,’’ an emergencies ministry spokesman told the Interfax news agency.

Reuters reported that a powerful blast had rocked the Urals region with bright objects falling from the sky.

theres nothing on NASA's website about that meteoriod.....
latest time updates have the asteroid at its closet point to Earth at 0530 tomorrow, saturday morning.

If youve got a Smart Phone you need to Download "ISS Detector "

If you go the the desert & watch the stars at night this ap is a MUST HAVE.

bit of a fizzer , I think, the times given didnt match up anywhere, appears the best actual footage came from Murrumbateman Observatory in Australia.....never heard of it. Will google to satisfy my curiousity. The meteor over Russia was better sky value last night.

Haa , thats so funny , I wonder if NASA know that Murrumbateman Observatory is a bloke with a telescope in his back shed near Yass.
Kudos to Him.
