The Main activity during this week has been the entrance in Quadrature on the 19 October 2007. The procedure was fully automated as part of the routine plan following the experience of the previous quadrature. The fake ephemeris was again applied in GSP before the AOS in Cebreros.

VIRTIS operations remained disabled during this period. The rest of observations took place routinely during this reporting period.

The table below shows a chronology of the main activities in the reporting period:


MET (Day) Date DOY Main Activity
