Description

This is the first time I have captured what initially appeared to be a shock wave in white light using a continuum filter BUT IT IS NOT!

If you use a PC or laptop you can see a small dark line progress north of the leading sunspot (the right hand side spot of this large active region). This is now proved to be optical train artifact caused by the image drifting across the CCD chip. Note that the progression remains at the same velocity and appears to extend in length as it moves northward and away from its point of origin it gives the appearance of a shock wave BUT IT IS NOT!

I checked the GONG images during this time and they show some C-class flaring during this imaging run but I have not been able to get at the daily NOAA flare reports.

Sorry for any confusion caused by the original post.
