JunoCam at PJ33
This page presents our report on the JunoCam images at PJ33 (2021 April 15).
The main highlight was in the South Temperate domain: the first closeup images of cyclonic spots DS6 and DS7 (“Clyde’s spot) for nearly a year. DS6 has changed from a dark brown oval into an orange-&-white oval sitting next to oval BA, while DS7 has become a miniature folded filamentary region (FFR).
Other highlights include:
NNTB: Closeup of a FFR with a methane-band image showing relative levels of clouds.
N. Temperate & Tropical domains: Comparison of cloud textures now that both the NTB and NEB are quiescent. In the NEB, a small bright orange spot that could be an early view of a plume that was to erupt 3 days later.
Circumpolar cyclones: Confirmation of the altered configuration of the northern polygon, and of the cyclic motion of the south polar cyclone.
