Lightning along Juno's path and sample stealth superstorm

Caption

NASA's Juno spacecraft passed north-to-south (yellow track) over Jupiter's atmosphere on 17 August 2022, detecting a cluster of radio pulses from lightning (cyan symbols marking instrument pointing for each pulse). Background map from the Hubble Space Telescope  identified the lightning source as an isolated "stealth superstorm." Inset shows a previous stealth superstorm plume (12 January 2022; 3x greater magnification) from JunoCam data.
