Catania region 51 was numbered NOAA 11055, together with NOAA 11054 (Catania 52) are the two active regions visible on the disc. They don't have potential for big flares at this time, even though AR 11054 is growing in size. There was an east limb CME yesterday at 20:06 UT detected by CACTUS, it is not expected to be geoeffective. Geomagnetic activity is quiet and will most likely remain so as the effect from the fast coronal hole solar wind is diminishing, there was one active period (Kp=4) early today.

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
DAY BEGIN MAX END LOC XRAY OP 10CM TYPE Catania NOAA NOTE
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.
