The SEPICA 30kV supply was shut down by the onboard DPU between Oct 25 and 26
(2000/299 and 300), because of a high current limit violation. So far, no
indications of trouble preceding the shutdown have been found in housekeeping,
but data analysis is continuing. This kind of shutdown happens occasionally,
but this time efforts to raise the supply voltage back up 30kV have resulted
in repeated automatic shutdowns.  Currently, the 30kV supply is at 2.4kV and
is usable at this level.  This allows for energetic particle composition
measurements, but not charge-state measurements.  The SEPICA team is studying
the behaviour of the supply current, which is higher than usual and is also
exhibiting some variability.  Consultations with the HV supply engineers and
lab tests of a spare HV supply are underway. More study is needed, but the
SEPICA team currently suspects a HV supply component failure.

On Nov 9, the SEPICA Fan 3 pressure dropped to ~4 torr, which is too low to
operate. This indicates that the Fan 3 pressure valve has spontaneously closed
most of the way, which has happened before. The valve can be commanded to open
again, but the SEPICA team prefers to wait and see if the valve reopens again
by itself. This reduces the risk of damage to the valve.  Fan 3 was the only
one of the 3 SEPICA Fans in operation.
