The above image is a collection of ten frames taken by the Atmospheric Imaging Assembly (AIA), at 131 Angstroms, aboard the Solar Dynamics Observatory (SDO). The center of each image is Active Region 1543 (AR 1543). The images were taken one minute apart on August 13th and range from 12:34 UTC through 12:43 UTC. They begin on the top row and progress from left to right, and then move to the bottom row and continue from left to right. The images feature the C2-class solar flare and the apparent expelling of a plasma cloud, or coronal mass ejection (CME). Image Credit: SDO/AIA
Back at Earth, the geomagnetic field was quiet to unsettled. In the forecast, the geomagnetic field is expected to be quiet to unsettled with a slight chance for activity on August 4th due to a high speed stream from a coronal hole. August 15th and 16th are expected to be predominately quiet. Stay tuned...
