Points Of Interest

SOHO Telemetry Submode changed to Submode 5 on 2004/04/13 at 16:00 UT 
(SUMER began observing on 2004/04/14). SUMER campaign runs until 2004/06/17.
In other words, LASCO synoptic observation plan cadence remains the same
but the EIT CME watch images will be reduced to half-resolution (512x512).

07:13 UT      	EIT Fe XII Time. EIT Fe XII images show a brightening on NOAA 
		AR 0599 at 07:13 UT (located by the time around N17E05)
		surrounded afterward by a strong dimming, likely signature of 
		a CME. An intensity disturbance is seen to travel across the 
		disk as the event develops. The event was associated with a 
		C3.1 X-ray flare that GOES records from NOAA AR 0599 between
		07:08 - 07:37 UT with peak emission at 07:23 UT.
