ASKAP observes solar Sun spots
by Maxim Voronkov (CASS)
During the last commissioning run we briefly had 16 PAF-equipped ASKAP antennas working as an array, ie. four more than in recent ASKAP-12 observations. We decided to observe the Sun as a demonstration of imaging with only limited hour-angle coverage. The first image was taken on the 21th of January and revealed a solar flare. For comparison see the Fe IX image of the Sun. Finally, observing the Sun for 15 min each day for five days resulted in the animation shown here.
