#X-CLASS #SOLARFLARE: Departing sunspot AR3664 (3697) produced another #X-flare today (1108 UT). The X1.5-class explosion occured just beyond the sun's western limb, and was partially eclipsed by the edge of the sun. As a result, it was not very geoeffective. The explosion did not reverse the decline of an ongoing radiation storm (described below), nor did it produce an Earth-directed CME.
