A Radio View od the 2017 Eclipse

Aug 22, 2017

Ever wonder what the 2017 eclipse would have looked like if you were a radio astronomer? Astronomy Professor Snezana Stanimirovic pointer our Small Radio Telescope atop Sterling Hall at the Sun during the partial eclipse seen in Madison on August 21, 2017 and took this lightcurve:

 

The SRT spent a few hours today looking at the Sun at 1417 MHz, observing radio waves emitted mainly by the lower Solar corona so the eclipse actually started earlier than 11:50 am. What you see in the figure above is how bright the Sun was during the eclipse, showing the dimming of the radio Sun as the moon crossed it. Notice the interesting shape and the fact that the radio eclipse lasted longer than the visible one!
