No. 153 - Eclipse Season
On DOY 291 a sudden drop in received automatic gain control at the Cebreros ground station resulted in extensive data loss (both science and housekeeping) between 14:51Z and 15:05Z. This was later confirmed to be due to heavy weather (thunderstorms) in the area. The data was recovered completely over the following few days.
The table below shows a chronology of the main activities in the reporting period:
