Near-Earth asteroid pass on 2/15: Threading the needle!
Feb 6, 2013

Asteroid 2012 DA14 is actually going to pass inside the ring of geosynchronous satellites orbiting the Earth on Feb 15. The closest part of the pass favors the Eastern hemisphere.

It's not a big rock at only about 50 meters in diameter. It's going to be about magnitude 7 so slim to none chance of a visual sighting but easy with binoculars (if you can point in the right direction) and it ought to be easy to record with a camera. It will be drifting across the sky at nearly one degree per minute which would be a bit of a challenge for an auto-guided mount. In a wide angle star-trailed picture it would look similar to a satellite pass.

Good luck and post some images if you get any!
