NEO 2005 WK4, August 9, 2013
|NEO 2005 WK4 at 8:30 UT 9 August, 3 and a half hours after closest approach. 6x15 second images taken with iTelescope T5. The images were stacked in ImageJ and a Max intensity Z project made, then despeckeled and inverted.The sequence is very gappy, like my last sequence, as cloud rendered most frames useless (I took 20 frames)||Animated gif from the 6 frames|
