Real Time Solar Wind plots stopped updating due to a server failure at approx. 03/1654 UTC. Currently, ACE and SOLAR1 data are unavailable. Our IT team is currently working the issue, hoping to restore data w/in the next 1-2 hours. Stay tuned for updates.

Geomagnetic activity in response to CMEs that departed the Sun on 25 Aug is now anticipated to extend into 29 Aug. A G1 (Minor) geomagnetic storm watch remains for 27 Aug for expected CH HSS influences and a G2 (Moderate) geomagnetic storm watch is now active for 28-29 Aug.

Region 4513 continues to produce M-class flare activity. Data provided by USAF ground-based observatories indicate that the latest event, an M2.2 flare, may have produced a relatively fast CME despite its impulsive nature. Further analysis is underway.
