Blue jet: (a) the cloud-top altitude of the storm cell over the South Pacific on February 26, 2019, at 15:10 UTC, derived from the Japanese Himawari meteorological satellite data and from a radio sounding at Tarawa at a distance of approximately 700 km (435 miles); the green curve is the ISS orbit and the red marker its position at 15:10:05 UTC; the black curves identify the full field of view of the cameras projected to the Earth’s surface, and the white square is the cropped image, downloaded from the ISS and shown in (b); black markers are the lightning locations detected by the GLD360 network between 15:10:00 and 15:11:40 UTC; (b) the cropped, downlinked ASIM image (777.4 nm) of the cloud backlit by internal lightning; the source locations of the five blue flash events detected between 15:10:00 and 15:11:35 UTC are shown with colored markers, time progressing from red to yellow. The flash leading to a blue jet is event number 3. Image credit: Neubert et al., doi: 10.1038/s41586-020-03122-6.
