Hello,

If you haven't already heard, there was some excitement over Thanksgiving
vacation.

The spacecraft is fine.

MGS did a pop-up maneuver at A51 (0.1 m/s) after hitting the yellow alarm
limit on dynamic pressure (0.33 N/m^2).  (last Friday)  The AAG reported
a significant storm and recommended going up one scale height (7 km).  A
second maneuver was performed (0.25 m/s) before P52 to accomplish this.

A low dynamic pressure (0.06 N/m^2) was seen on P52.  Variability has
been more than 70% for orbits 47 - 52.  The spacecraft has remained at
this new altitude for P53 and P54.  A decision about P55 is currently
being discussed.
