Patrick - that's a fascinating image. What was the exposure time? Can you estimate the width of the field of view? It'd be interesting to try to estimate the speed and rate of rotation of the interloper.

It was a 15 second exposure. FOV is about 18x26 arc seconds. On 06 Jan 2014, at 08:36, 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. But - to have only covered about 9 arc-min in the sky in 15 seconds puts it in a very high orbit, comparable to satellites that are ~25,000 km above Earth. But this is _not_ an object in geosynchronous orbit, which is much higher. This _is_ approximately the median orbital altitude of a GPS satellite. But do they rotate that fast? Interesting stuff.

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:

Do GPS satellites spin that fast?

Wow, it that what a "Pulsar" looks like? :) My vote for the mystery object is a plane with flashing lights. ________________________________ From: Wiggins Patrick <paw@getbeehive.net> To: Astronomy Utah <utah-astronomy@mailman.xmission.com> Sent: Monday, January 6, 2014 4:57 AM Subject: [Utah-astronomy] What were the chances?

That's my guess. Brent probably heard I was running a search and decided to put in an appearance. :) patrick
Yes, careful navigation, timing, andflight at 55,000 feet was the secret. Actually, I think it is space junk. It is moving too slowly for an airplane.

Looks like Brent was right about it being a satellite. I posted the data on the Minor Planet Mailing List and a fellow in the Netherlands who tracks such things determined it was a GPS satellite called NAVSTAR 19. http://www.n2yo.com/satellite/?s=20533 patrick On 07 Jan 2014, at 07:31, Brent Watson <brentjwatson@yahoo.com> wrote:
