Abstract
The current measurements from the Sentech tower for the 2020–2021 rain season are presented. The tower is a cylindrical concrete radio broadcast tower, situated on the highveld plateau in Johannesburg, South Africa. The season produced 43 distinguishable lightning current measurements, 186 return strokes, 30 ICC fast pulses and 7 ICCOnly events. The return stroke multiplicity for the season is 6.41. The return stroke median current is 7.51 kA while the ICC pulses had a median peak of 3.75 kA. The median charge transfer for a lightning event with return strokes is 41.36C, while it is 35.51C for ICCP events and 26.08C for ICCOnly events.
