Most of these images are from Clay Sherrod, as shown in the first montage. It is interesting that barge B3 (the more southerly, prograding one) was actually very faint from Oct.31 to Nov.5, but darkened again as the interaction began on Nov.7. The second montage shows enlargements of these images after the barges began to interact on Nov.7. The cores of the two barges were very close on Nov.12, then the pictures on Nov.13 and 14 show a variable dark spot --possibly one dark barge with the variable remnants of the other orbiting cyclonically around it. The third montage shows hi-res images by several other observers with enlargements or map projections of the barge interaction region. Does anyone have such hi-res images since Nov.12? Also note oval BE in all these images, approaching the GRS - but itis now quite small and low-contrast in visible light (though still conspicuously bright in Akutsu's methane image of Oct.27). Clear skies! John Rogers.
