2011 Animations from 2011 JUN 24, 25, 26 & 27
Morning, Glad to hear that Kurt was able to see 2011 MD this morning. Anyone else have any luck with it? Just hours from closest approach and it's quite bright and really moving fast. Unfortunately it will be daytime here when it's at it's closest approach so I wont get to see it then. Grumble. At any rate, what follows is a compilation of all my 2011 MD animations. Details for all animations: Paramount ME, C-14 operating at f/5.5, ST10-XME binned 3x3, -10°, clear filter. FOV ~18x26 arc minutes. North up, east to left. 2011 MD moves from upper left to lower right in all but the last two. 2011 JUN 24 40-60 second exposures, each taken 2 minutes apart, between 0716 and 0916 UT.
