Fig. 3.


LOFAR multi-frequency maps at ingress, maximum phase, and egress of the partial solar eclipse on 2015 March 20. Time increases from left to right, whereby the first column is 08:45 UT, the second column is 09:45 UT, and the third column is 10:45 UT. Frequency increases from top to bottom of the grid. The top row is the 120−140 MHz multi-frequency band, the middle row is the 140−160 MHz multi-frequency band, and the bottom row is the 160−180 MHz multi-frequency-band. In each image, the solid white circle is the visible solar limb and the pink dashed outline is the lunar limb. The white ellipse in the bottom left corner of each image is representative of the beamsize.
