a Location of pulsating (zenith) arc relative to the KRN and TJA observatories (white squares). b Keogram showing the temporal variation in auroral brightness sampled along the south to north cross section. A series of bright patches on the keogram reveals the main pulsations of the arc intensity, and vertical strips inside the patches are the signature of quicker scintillation
