Detection of spike-like structures near the front of a shock-driven solar radio burst
Type II solar radio bursts are the result of energetic electrons accelerated by a shock. This kind of burst appears on dynamic spectra as lanes drifting slowly from higher to lower frequencies. Often, scientists observe a fundamental harmonic structure, which sometimes exhibits a division on each band called band split.
