Observations just completed, with the 30 cm refractor at Cambridge,
showed five sites. Site A is obviously fading, and E,A,C are no longer
evenly spaced as they were in the July 17 Hubble image. They transited
on July 19 at UT 19.44, 20.23, and 21.31 (+/- 2-3m). Here are our System II
longitudes, compared with those reported by Pic du Midi on July 17:
Cambridge Pic du Midi Chodas
July 19 pm July 17 pm pred.
----------- ---------- ------
H Near p. limb -
E Looks exactly like a sat. shadow: 83 75 79
A Large but faint - has faded: 107 110 107
C Small dark core? (Lo-res): 148 147 147
K Large & dark like G yesterday (Lo-res) -
Seems that E is retrograding. (I will work out System III as well to compare with others' reports, soon.)
Mark Sykes will be pleased to know the 'public involvement' was heavy; we were glad to show the the scars on Jupiter to lots of visitors, though it did compete with serious observations!
