R3-Radio Blackout Storms (Strong) are currently in effect. Region 1520, located close to center disk, is the culprit on today’s events. It is still to early to see if an Earth-directed CME or energetic particles are associated with this event, however SWPC forecasters are monitoring the situation. Stay tuned for further information on this event and other Space Weather news.
Effective Wednesday, July 25, 2012, at 1600 UTC (10:00 AM MDT), SWPC will modernize its geomagnetic storm watch products. These products will now be issued relative to the highest expected geomagnetic storm category (NOAA Scale) and will be based on the 3-hour geomagnetic K-index rather than the 24-hour A-index. Watch products will still be valid for the entire UTC day, just as they are under the A-based watches today. This change will better align SWPC’s geomagnetic watch products with its geomagnetic warning and alert products and NOAA Scale designations. Product Subscription Service customers are not required to take any action regarding this change. The current A-based watches contain expected geomagnetic storm scale (G-level) information so all subscriptions will be automatically transferred to the new G-based watch products.
