A unique and huge disturbance started at the end of March 2007 in the strongest Jovian atmospheric jet at 24deg N with the eruption of two bright plumes followed by a dark albedo turbulent pattern which fully changed the jet structure and the belt/zone pattern at this latitude. This kind of disturbance is rare in Jupiter, the last one was observed in 1990 but only at low resolution. Up to now we have studied the 2007 event using a battery of ground-based instrumentation (with visible and infrared wavelength coverage), and after 40 days of development, the two plumes have extinguished whereas the disturbance has fully encircled the planet, forming a new dark belt. We have HST WFPC2 high resolution images of the belt/jet structure at 24deg N before the eruption. Those images were taken in January and February 2007 to support the New Horizons flyby, and now we require new observations of the new belt and jet following the disturbance, to compare both stages and determine its action on the jet wind profile and belt/zone cloud vertical structure. This comparison will provide for the first time valuable information on the maintenance, variability and origin of Jupiter jets and cloud banding.

Observe Jupiter immediately after a North Temperate Belt upheaval to determine the effect on the zonal winds. 4 orbits, each spaced 5 hrs apart, allows winds to be measured at all longitudes. 0 false 0.0 false false false false false false SUPPORTED SOLAR SYSTEM 25 degrees north latitude PLANET JUPITER-NTB STD=JUPITER TYPE=POS_ANGLE,RAD=6.0,ANG=20.0,REF=NORTH SEP OF JUPITER-25N IO FROM EARTH GT -17.0", SEP OF JUPITER-25N EUROPA FROM EARTH GT -14.0", SEP OF JUPITER-25N GANYMEDE FROM EARTH GT -7.0" First orbit - any CM longitude is acceptable.
