Prominence Eruption
A prominence eruption was observed Thursday morning off the western limb and it generated a bright, westerly directed coronal mass ejection (CME). Although the CME is significant, it should have little to no impact on our geomagnetic field. Imagery by SDO and LASCO.

M6.5 Solar Flare
Expanding region 2113 located in the northeast quadrant just produced an M6.5 solar flare at 16:20 UTC Tuesday. The event was associated with Type II radio emission with an estimated velocity of 949 km/s. A coronal mass ejection was flung into space, but was directed to the northeast and away from Earth.

ALERT: Type II Radio Emission
Begin Time: 2014 Jul 08 1614 UTC
Estimated Velocity: 949 km/s
Description: Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event.

ALERT: Type IV Radio Emission
Begin Time: 2014 Jul 08 1604 UTC
Description: Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms.

Weak Shock Passage
Good evening. The Bz component of the interplanetary magnetic field (IMF) is currently shifting south. Early Wednesday evening a weak shock passage was observed by the ACE spacecraft just after 23:00 UTC. A geomagnetic sudden impulse measuring 21 nT was detected at 00:41. Minor geomagnetic activity at high latitudes may be possible tonight.
