The X2-class solar flare began at about 2.50pm AEST or 04.50am UT…it was a very exciting event to witness :-)
Images taken with a Lunt 80mm solar telescope with a Canon 700D camera and 5x Barlow lens. Exposures were 1/80th second and ISO 400. Twenty images stacked in RegiStack6 and processed lightly in PS CS4.
The monochrome image was taken with the same telescope and camera but with a 2x Barlow lens for a wider view.
X2-FLARE AND RADIO BLACKOUT: All week long, sunspot AR2297 has been crackling with solar flares. Today it produced a really big one. On March 11th at 16:22 UT (09:22 PDT), Earth orbiting-satellites detected an X2-class flare. The blast zone was larger than Earth itself, as shown here in these images below from NASA's Solar Dynamics Observatory:
