Late Fall Night Sky Anomaly. Super-Nova or Geminid Meteor Comming at Me?

The sky was clear Thursday night. I had three cameras out to capture Geminid meteor trails. Friday night the sky was also clear, so stayed up again to capture any late Geminid meteor trails. After being up two nights in a row, I really needed to catch up on some sleep. When I started to review the images today, I found an anomaly in the star trail image between 2-3 AM Friday morning. The images for this composite were taken on a Nikon D4 with a 14-24 f/2.8 lens. I have trouble with condensation on this lens and this night was no different and because it was cold frost formed on the center on the lens. The result is that light getting to the center of the image is significantly attenuated. I didn’t expect to see anything in the center area because of the frost — but there was one bright star. The unusual star is actually brighter than Sirius. I went back and reviewed the individual images, and found that this “star” only appeared at 02:19 AM — not before and not after. I checked the images from the other two cameras. The D800 with a 16 mm f/2.8 fisheye lens covered the same space, and indeed it also captured the same anomaly. I didn’t see any news about a super-nova, so did I capture an image of a Geminid meteor coming right at me? Good thing that they burn up in the atmosphere!!
