"Hi Mariusz,
I was informed that PROMPT took imaging of the source and didn't see anything there. GROND will let me know its results sometime soon.
Without your data files in hand, it's hard to be sure, but it does not appear to be a cosmic ray. With a long exposure, you would get many CRs and they would be smaller than the seeing FWHM. Was the image that you sent a stack of multiple images or a single image?
Because the source is not seen now, it might be an internal reflection or ghost of Eta Carinae, some unknown fast transient, or some artifact.
Let me know if you get a chance to image it again and if it appears. Be sure to take multiple exposures and to image with different camera orientations (to minimise reflections in the same spot). It would be great if it was a shock breakout and the event rebrightens.
All the best,
- Jeff"
I am imaging the same area again tonight.... see if anything flares up... but if there is a SN in the near future right next to Eta Carina, than a shock break out is what it was....
I attached the image I sent to the pros, a sub where the light appeared (my last sub for the night) and the sub before.
