Event times are first frame seen in C2 camera unless otherwise noted.
These are preliminary observations for the daily SOHO science discussions.
Final analysis is reported on the Lasco CME list.
An archive of these reports is available.

Points Of Interest

MERCURY entered the C2 FOV (from the right) on 2004/06/17 (Thursday).

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).

SOHO Telemetry Submode changed back to Submode 6 on 2004/06/17
(Thursday) at 14:45 UT. SUMER door is already close. 

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).

			surpassed) by a spray-like front. They both fade 
			throughout C3.

03:12 UT  E Limb	Small blob-like front. It fades throughout C3.

19:12 UT  E Limb	Very faint ragged loop front that quickly fades (C2).
