Here I was filming AR1429 on the 4th March 2012 here is a movie produced between 10:33 and 11:41UT, an M1-class solar flare breaks above the active region and this produces a solar shock wave - this resembles the ripples in a pond when you throw a stone into it. The seeing conditions were excellent grade 1. I used my standard PST with DMK21 monochrome camera on a hand driven alt azimuth mount. Here I was shooting 300 frames every minute but I only animated every 4th minute at the same time as I corrected for field rotation in Photoshop CS5.
