Jupiter in 2025/26, report no.5:  Some fine images around New Year and Opposition

This bulletin simply presents four sets of the wonderful hi-res images of Jupiter taken by various observers around New Year 2025/26, and a labelled map from 2026 Jan.20-21.

{1}  Hi-res images showing the GRS, around New Year 2025/26.

{2}  On Dec.30/31 a transit of Ganymede with its shadow was very well recorded from western Europe, along with Io emerging from occultation.  On the right are 4x enlargements of the satellite images, showing real surface features.  On Jupiter, oval BA and spot Q can be seen.

{3}  Satellite transits beside or in front of their shadows around opposition on 2026 Jan.10.  All are of Io, except for Ganymede (Jan.7) and Callisto (Jan.10, actually at the time of opposition).  This view by Christofer Mauricio Baez Jimenez in the Dominican Republic is the only known resolved image of this rare event.

{4}  Hi-res images showing the GRS, 2026 Jan.14-17.

{5}  Map on Jan.20-21, made by Simon Labergere (France) from his own images over just two nights at the Mont d’Arbois Observatory. (Note that the scales of longitude (L2 and L3) and latitude (planetocentric) differ from our usual conventions.)
