Asteroid YU55

[brascoe]

with this passing inbetween the us and the moon on the 8th of next month what would be needed to have a good view of this would it be just a half decent set of binos ?

[ncjunk]

It will be magnitude 11 but i have no idea what mag you can get down to with bins. Looks like an interesting target.

yeah was just reading about it in next months edition of sky at night but knowing uks luck with weather etc will be cloudy or snowing lol:D

[Hypernova]

Is there anywhere that will be posting coordinates and finder charts for this close approach? It could be an interesting target to follow in the dob depending on the brightness and the speed at which it moves across the sky.

[StarDome]

Anyone found any charts for it yet? its gonna be in Lyra isnt it?

Got the info now, its heading through Pegasus and into Pisces

Its in the bbc sky at night mag tells you everything you need to know.

You can find its details here

This is an extract from the Horizons website, showing the co-ordinates and magnitude on an hourly basis around close approach. At close approach, which will be on the 8/9th November it reaches about 11th magnitude and will be racing across the sky at a rate of several degrees per hour.

Stellarium says its currently mag 31.5 !

Lets hope it gets a bit brighter

EDIT:It also says it'l be next to the beehive (M44) :-)

but with the moon a few degrees away :-(

Or is Stellarium wrong ? I hope so,

Anyone know how or where I can find out where/when the asteroid will pass by for us in the US? I tried looking on Stellarium but it doesnt have it.

Completely cloudy here. Typical
