Solar activity is expected to remain quiet within the next 24 hours, with a slight chance for a C flare. Geomagnetic conditions have been quiet. Active periods are possible on February 3 and the first part of February 4, due to an anticipated coronal hole high speed stream. Afterwards, mainly quiet conditions are expected.

Details
The Geoalert message starts with the code GEOALERT BRUXXX, where xxx is the day-of-the-year number.Besides the ISES codes like UGEOA, UGEOI, UGEOR and USSPS, this message contains the following information:
PLAIN
PREDICTIONS FOR "today" : 10CM FLUX: xxx / AP: xxx
PREDICTIONS FOR "today+1": 10CM FLUX: xxx / AP: xxx
PREDICTIONS FOR "today+2": 10CM FLUX: xxx / AP: xxx
99999
This gives the predicted 10.7 cm radioflux and the predicted Ap index for 3 days starting on the date of the message
