PREDICTIONS FOR 17 Jan 2018  10CM FLUX: 071 / AP: 003
PREDICTIONS FOR 18 Jan 2018  10CM FLUX: 072 / AP: 007

COMMENT: Over the past 24 hours solar activity has been quiet. No
significant flares have been recorded. Active Region (AR) 2696 (Mcintosh
class:Cro; Mag. type:Beta) is the only region on the disk, but has been
quiet. There are no other significant ARs on the solar disk. No Earth
directed Coronal Mass Ejections (CMEs) have been detected. Solar activity
is expected to remain low over the next 24 hours with a small probability
of C-class flares.
The solar wind speed has decreased from around 440 to 350 km/s over the
past 24 hours. The total magnetic field strength has remained around 5 nT.
The Bz component fluctuated around 0 nT, ranging between -4 and +4 nT.
Geomagnetic conditions ranged between Kp index 0-1 (NOAA) and local K index
0-2 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected
to be quiet.
TODAY'S ESTIMATED ISN  : 017, BASED ON 12 STATIONS.

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
