Points Of Interest

MERCURY LEAVES the C2 FOV 04:48 UT on 2004/06/17.

SOHO is now in a telemetry keyhole (2004/06/16 - 2004/07/03). LASCO data 
will consist of typically two (occasionally three) continuous periods of
real-time data per day.

On 2004/06/21 (Monday), 15:30 UT, LASCO will be safing for S/C maneuvers 
and roll to -180 degrees (on 06/22). It will re-open on 2004/06/24 
(Thursday) at 14:30 UT. LASCO will remain idle during this period and 
resume its improved cadence program shortly after. 

EIT 195 CME watch was interrupted on 2004/06/15 (Tuesday) at 15:00 UT
for EIT CCD bakeout calibrations. EIT CCD bakeout started on 2004/06/15 
at ~ 20:00 UT. EIT CCD bakeout until 2004/07/04 (Sunday).

LASCO C2 and C3 will be in high cadence during the rest of the week: 
C2 at a 12 minute cadence, C3 at the 30 minute cadence.

MERCURY entered the C3 FOV (from the right) on 2004/06/12 (Saturday).
