a STEC time series showing dominant TEC anomalies accompanied by several small positive peaks (indicated by red arrows). Because this Es patch was moving southward, the period earlier than 01:15 UT represents the front side of the structure. b VTEC anomaly map at 01:15 UT, showing a patchy frontal structure elongated in E-W. c SIP positions with satellite 12 and the three GPS stations at 01:15 UT. Satellite 12 moved northward across the Es in the time window of a
