Possible Impact on Jupiter

As reported from Australia, a possible impact has been observed on Jupiter on the southern hemisphere, at a latitude similar to the one, where the occultation re- and disappearance will happen. Up to now it is not clear, what possiblities in the detection of atmospheric turbulances and absorption may result from this event.

In any case, the longitude of the impact was around 216 degree in system II, which results in the following table for the 3^rd of August. Time is given in UTC:

UTC(3.Aug)   Zentral    Disappear    Reappear
23h 00      202 deg      292 deg     112 deg
23h 30      220 deg      310 deg     130 deg
24h 00      238 deg      328 deg     148 deg
24h 30      257 deg      347 deg     167 deg
25h 00      275 deg      365 deg     185 deg

The position of the impact is at 216 deg in System II. Therefore we are a little bit unlucky, that the spot is neither close to the disappearance- nor to the reappearance point. But may be, that there is some disturbance over a larger area in two weeks....

Data were calculated using XEPHEM V 3.7.3
