Do GPS satellites spin that fast? Curious. -----Original Message----- From: utah-astronomy-bounces@mailman.xmission.com [mailto:utah-astronomy-bounces@mailman.xmission.com] On Behalf Of Chuck Hards Sent: Tuesday, January 07, 2014 9:45 AM To: Utah Astronomy Subject: Re: [Utah-astronomy] What were the chances? Seth, look closely at the brightenings. Every other one is a bit dimmer. I think the rotation rate is about half of your estimate. Still pretty fast, but closer to ~44 rpm.

This is now really interesting!
The interloper in this image of NGC 3992 (M109) appears to have made 22 rotations in 15 seconds. That's ~88 rpm.
Wicked fast.
