Update on Juno/MWR measurements of lightning on Jupiter

In October 2023, Juno will have completed fifty-four perijove passes (PJs). The initial report of 377 lightning sferic events detected by Juno (Brown et al. 2018) covered seven PJs, from August 2016 to September 2017. We report an update to Juno’s lightning detections using MWR using the complete data set from all fifty-four PJs, focusing on the spatial distribution of the lightning, its power spectrum, and correlations between clusters of sferics and specific atmospheric features seen in context observations from Earth based telescopes including the Hubble Space Telescope.

We expect to accumulate a dataset of about 9300 lightning events by PJ 54 (September 2023). We will present an update on this dataset, focusing on the spatial distribution of lightning, its power spectrum, and correlations between clusters of sferics and specific atmospheric features seen in context observations from the Hubble Space Telescope and other sources.
