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 SIDC ursigram starts with the code SIDC URSIGRAM YMMDD, whereY is the last digit of the year number,
MM is the number of the month,
DD is the day of the month.
A forecast is given on:
the global flare probability,
geomagnetic disturbances,
solar proton events.

NOTICEABLE EVENTS SUMMARY
DAY BEGIN MAX END LOC XRAY OP 10CM TYPE Catania NOAA NOTE
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.
Check the ISES code book for information on ISES codes.
