Top: original complex radio dynamic spectrum with broadband pulsations that lasted 70 s (9:33:57−9:35:07 UT) and was observed by the Badary Broadband Microwave Spectropolarimeter. Bottom: averaged global wavelet spectrum (AGWS) made from the spectrum in panel a) with strong peaks at periods P = 2.35, 4.64, 16.68, and 30.30 s (blue arrows) and with local minima at periods 0.07, 1.49, 3.03, 5.83, 21.54, and 40.26 s (red arrows).
