NOTE: the above forecasts are valid from 1230UT, 08 Feb 2010 until 10 Feb 2010
PREDICTIONS FOR 08 Feb 2010  10CM FLUX: 092 / AP: 007
PREDICTIONS FOR 09 Feb 2010  10CM FLUX: 092 / AP: 020

COMMENT: Solar activity stays at active levels: NOAA AR 1045 released
today, Feb 08 more M-flares: an M4.0 flare peaking at 07:42UT
(information from IPS flare report), an M2.1 flare peaking at 12:47UT
(information from 1 min GOES-14 X-ray Flux data). The first glimpse of a
CME is visible in STEREO Ahead COR2 pictures at 06:39 UT. The CME
propagates towards the Earth. Geomagnetic activity is expected to
increase to major storm level on Feb 09 as consequence of the arrival of
the halo CME associated with the M6.4 flare on Feb 07, peaking at
02:34UR. More geomagnetic disturbances can be expected as the CME seen
by STEREO reaches Earth.

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
NOTICEABLE EVENTS SUMMARY

This is the header of a table that lists all major events.
DAY gives the day-of-the-month.
BEGIN, MAX and END give the UT time of the different phases of the X-ray output of the event.
LOC gives the location of the event in heliographic coordinates.
XRAY gives the GOES X-ray class of the event.
OP lists the optical flare class.
10cm gives the 10.7 cm radioflux output of the event.
TYPE specifies the type of radiobursts observed.
Catania gives the Catania sunspot group number where the event happened.
NOAA is the corresponding NOAA active region number.
NOTE is the header of any other type of information, e.g. if a CME was observed associated with the event.
