AIA 171 Å image at 03:51:47 UT and red, green, and blue overplotted contours (50, 55, 60, 65, 70, 75, 80, 85, 90, and 95% of peak of flux) represent 101, 165, and 298 MHz radio frequencies, respectively. The yellow arrow indicates the location of the jet eruption. Orange and magenta lines indicate closed and open field lines, respectively, which are derived from the extrapolation. The red, green, and blue colored squares show the locations along extrapolated magnetic loops where the local fundamental plasma frequency is expected to be 101, 165, and 298 MHz (see text), respectively.
