Region 2403 Produces R2-Moderate Solar Flare Activity

Region 2403 Produces R2-Moderate Solar Flare Activity
published: Monday, August 24, 2015 20:03 UTC

Region 2403 (S15W18, Fkc/beta-gamma-delta) produced an M5/1B (NOAA Scale R2-Moderate) solar flare at 24/0733Z (24/01:33am MDT). SWPC forecasters are awaiting SOHO/LASCO C2/C3 imagery to determine any potential coronal mass ejection (CME) impacts to Earth. Although this flare is bigger than we have seen in some time it was very impulsive and lacked typical radio signatures that are often associated with CMEs. We will update as additional data becomes available. Here is a link to a related NASA newsfeed: http://www.nasa.gov/feature/goddard/sdo-images-of-a-mid-level-solar-flare
