Top: M-band radiance maps of Loki Patera (integrated from 4.5 to 5 μm) taken during Juno’s orbits 51, 55, 57, 58, and 60. The observations taken during orbit 47 are at very low spatial resolution (pixel size was ∼100 km), and partially saturated, but they reveal the onset of the cycle. Observations from May 16 (orbit 51) are also partially saturated. Observations from orbit 58 (2024 February 3) have a stripe that is an instrument artifact. Observations from orbit 60 (2024 April 9) are saturated in the bright feature at 49°E, 12°N in both bands. Bottom: L-band radiance maps (3.3–3.6 μm). Orbit 57 has no L-band observations; hence, we use that panel to show the locations of zones 1, 2, and 3 (see text for details). The cyan arrows indicate the direction of the sub-spacecraft point at the time of the observation (that is, the approximate direction from which Loki P. is seen); the cyan numbers indicate the value of the emission angle (0° corresponds to looking at Loki P. vertically). Note that the color bars for the radiance are not linear; the supplementary color bars on the right show the corresponding brightness temperature associated with the measured radiances.
