COMMENT: A long duration C7 flare was observed 0325-0706 UT. 
This flare appeared to be associated with a mass ejection on 
or behind the eastern limb of the sun. As such this CME is not 
directed towards the earth and is not considered geo-effective. 
Some bright emmission can be seen around the north-east limb 
in LASCO eit imagery and some spots may be rotating around the 
limb.
