North Polar Cyclones - Juno - From Aster Cowart (terrasabaea.bsky.social) - https://flic.kr/p/N4ygvs
Juno Jovian Infrared Auroral Mapper (JIRAM) mosaic of heat emission around Jupiter's north pole. Brighter colors correspond to warmer temperatures. The swirls are due to the variable density of clouds in this region. Jupiter is constantly radiating massive amounts of heat into space, but the heat is often blocked by clouds before it escapes. Thicker clouds cause portions of the scene to be colder than others. This image was taken during the Perijove 5 close approach to Jupiter on March 27, 2017.

Wow, this looks exactly like the five cyclones around Jupiter's South Pole.
agupubs.onlinelibrary.wiley.com/doi/full/10....
Figure 1 from Gavriel&Kaspi, 2022 Five cyclones surround one cyclone at South Pole of Jupiter. Figure caption reads: Infrared radiation photograph of Jupiter's south pole taken by the JIRAM instrument on Juno. The black point represents the pole. The dashed lines represent intervals of 60° longitude (longitude 0° in System III is the line going “upward” from the pole). The green 'X's are the estimated location at the centers of the south polar cyclones during PJ4. Image credit: NASA/JPL-Caltech/SwRI/ASI/INAF/JIRAM.

I've been working on these images for the last couple of days measuring hot spot intensities, but there are a couple of mosaics:
M-band mosaic of Io from Juno JIRAM, acquired August 18, 2024. Bright spots are thermal hot spots from Io's volcanoes. L-band mosaic of Io from Juno JIRAM, acquired August 18, 2024. Bright spots are thermal hot spots from Io's volcanoes.

So a lot of non-imaging science I missed like the snapshots by JIRAM across Io's surface in the infrared, or gravity science over the leading hemisphere to complement Galileo's anti-jovian passes.

(3/n) My task for this paper was to navigate each JIRAM frame of Io using NAIF SPICE kernels, limb fitting, and tie points; reproject each to a common map projection; create an averaged product for each "observation"; and measure the output for each hot spot in the scene.

earlier estimated to cover an area of 300 square km with a total power output of 34 GW. JIRAM results show that the region produces a power output of 140-260 TW, over 1,000 times higher than earlier estimates. Three adjacent hot spots also exhibited [3/7 of https://arxiv.org/abs/2503.20450v1]
