Earth Fly-by I

Earth Fly-by activities in March 2005

Between 1st March (0:00h UTC) and 7th March (24:00h UTC), the first Earth Fly-by phase was supported from the PHILAE control center in Cologne.

During this timeframe, Philae was activated in order to take photographs of our planet with its panoramic camera system CIVA-P. In total, five pictures were recorded on 4th March between 19:54h UTC and 22:49h UTC. Additionally, the magnetometer ROMAP-MAG was switched on (1st March 01:00h UTC) to perform a calibration with the well-known magnetic field of earth.
