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. On Tue, Jan 7, 2014 at 9:29 AM, Seth Jarvis <SJarvis@slco.org> wrote:
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.
