PLAIN
NOTE: the above forecasts are valid from 1230UT, 25 Oct 2017 until 27 Oct
2017
PREDICTIONS FOR 25 Oct 2017 10CM FLUX: 079 / AP: 041
PREDICTIONS FOR 26 Oct 2017 10CM FLUX: 079 / AP: 040
PREDICTIONS FOR 27 Oct 2017 10CM FLUX: 079 / AP: 021
COMMENT: Quiet solar conditions were reported with the X-ray flux touching
only marginally into the B level.
Both active regions on disk are relatively simple (Mag.Type: Alpha) and
quiet.
The X-ray flux is expected to remain below C level.
Proton flux levels were at background values and are expected to remain
so.
No Earth directed CME's were recorded in coronagraph data.
Solar wind speed increased further as expected under the influence of the
coronal hole high speed stream. Speeds increased to values between
600-650kms after 20UT and remained at those values since. Total magnetic
field was mostly in the 7-11nT range but presently steady at around 5.5
nT.
Bz was variable but saw some periods of negative values down to -9nT. The
phi angle was predominantly in the positive sector.
Total magnetic field is expected to remain around nominal values while
solar wind speed is expected to remain elevated over the next 24-48 hours.
Geomagnetic conditions reached some periods of minor geomagnetic storming
(Both NOAA Kp and local K Dourbes 5 for the 15-18UT period, while only
NOAA
Kp reaching 5 in the 6-9UT period).
As solar wind speed remains elevated further minor geomagnetic storming
episodes should be anticipated.
TODAY'S ESTIMATED ISN : 023, BASED ON 16 STATIONS.
