No you wont need a Telescope for this one folks?

Post by David Webb »

An unusually large Near-Earth Object, 2012 LZ1 has just been discovered by Rob McNaught and colleagues on 2012 June 10/11, when it comes over about 11.10PM on 14 th June 2012 it will be very brightly lit up, and you will be able to see it with the unaided eye.
It is about 1.600 foot by 500 foot wide in size, it has been said it will not hit Earth on this pass but never mind I am sure it will come round again.

See it with the unaided eye?

Only if it were 1585 times brighter.

Stella is, as usual, quite right. This will be about magnitude 14, which will require a fairly large telescope to be seen.

But that won't prevent people from saying they have seen it whizzing through their sky!

What about if we get 1585, or perhaps 1586, amateur astronomers holding hands, will we see it then by combining our effort?
It might help if we all take deep breaths and eat lots of carrots.

It won't "come over" - it will pass at 14x the lunar distance , magnitude around 14.5. Have a look at today's spaceweather.com. Yo might see it with a 1-metre telescope........

Pah! :wink:

Two bright passes of the ISS tonight - from 22h17 and 23h51 BST respectively- I wonder how many will be fooled into thinking it's the asteroid? :)

Assuming the cloud clears (rain here)
