SIDC Latest human moderated alert

The forecaster on duty at the SIDC observes and processes all relevant Space Weather data, including automated feature alert processes. Based on his/her observations the forecaster on duty triggers alerts where automated processes have failed or are late and follows up and provides complementary information on the automated alerts.

NOOA Kp has reached moderate storm conditions (Kp = 6) during the 3-hour interval 3:00-6:00 UTC on March 1. K Dourbes was 4 (active conditions) during the same interval. This enhanced geomagnetic activity is related to an enhancement in the solar wind since 21:30 UTC on February 28, with solar wind speeds up to about 520 km/s and magnitude of the Interplanetary Magnetic Field up to about 15 nT. Bz was below -10 nT during the aforementioned interval, and is currently close to 0. Minor geomagnetic storm conditions (K Dourbes = 5) are possible on March 1, with a chance for moderate storm intervals (K Dourbes = 6).

SIDC Solar GOES-flare alert

The SIDC data processing pipeline analyses incoming GOES X-ray data in near real time and reports on the occurrence of X-ray flares of Classes M5 and up. The detection method includes the identification of start, peak and end time of the flare and includes a delay of 30 min to assure the reliable detection of the end time.

SIDC/CACTus Automated halo CME alert

The near real time detections of coronal mass ejections by the CACTus software (product S111) produce alerts as soon as the angular width exceeds 150 degrees. The alerts can be queried and (from 06/04/2004 onwards) the underlying detections as provided in S111 can be consulted.

SIDC Human operator alert moderation

The forecaster on duty at the SIDC observes and processes all relevant Space Weather data, including automated feature alert processes (such as the S112a and S112b products). Based on his/her observations the forecaster on duty triggers alerts where automated processes have failed or are late and follows up and provides complementary information on the automated alerts. Presently such "Presto" messages are in general undifferentiated and unconnected messages but the present version introduces the ability to display and query the connection with earlier "Flaremail" (S112a) and "CACTus alerts" (S112b).
