RADIATION SUMMARY
-----------------
Solar soft proton flux is Low. (http://www.srl.caltech.edu/ACE/ASC/)

Significant solar activity yesterday: Solar flare activity was very
low. No C class flares were observed.(http://www.dxlc.com/solar/)

CMEs reported for past two days: February 16-18: No obviously
geoeffective CMEs observed. (http://www.dxlc.com/solar/, Jan Alvestad)

Notes from 9 am meeting

     Dump status     Current
     Data loss       None
     Load is good -> 053:09:07 UTC

     Next passes     050/2345-0145	DSS 66

		     051/1145-1345	DSS 16

MP: The FEB2403A load products will be out today, with an email review
tomorrow. We need to reschedule one perigee attitute, and there are
some Jupiter pointing issues.

S/C The PSMC toggled and the translation motor went over 45 F. This
was expected at these attitudes. No temperatures exceeded past
highs. There have been some gyro bias variations over the past several
days; also gyro bias current has been variable. These gyro results are
not of concern, but are being watched carefully.

GOT/IST:

DATA:-

SOT: GOES x-ray flux: No significant x-ray activity today.
