The Kilauea eruption began at 0115 UTC on 11 September (3:15 PM HST on 10 September) — and about 15 minutes later, the GOES-18 3.9 µm Shortwave Infrared brightness temperature sensed at the volcano summit reached 137.88ºC (below) — which is the saturation temperature of GOES-18 ABI Band 7 detectors.
