SIDC URSIGRAM 90115
SIDC SOLAR BULLETIN 15 Jan 2019, 1230UT
SIDC FORECAST (valid from 1230UT, 15 Jan 2019 until 17 Jan 2019)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Active conditions expected (A>=20 or K=4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 15 Jan 2019  10CM FLUX: 070 / AP: 007
PREDICTIONS FOR 16 Jan 2019  10CM FLUX: 070 / AP: 017
PREDICTIONS FOR 17 Jan 2019  10CM FLUX: 070 / AP: 013
COMMENT: Solar X-ray flux remained below B level throughout the period.
There are no active regions on disk and X-ray flux is expected to continue
to be below C level.

No earth directed CMEs have been recorded.

The proton flux levels were at background values and are expected to remain
so.

Solar wind was close to nominal with Solar wind speed recovering from
around 400 km/s at the start of the period to a minimum of 330 km/s, while
presently around 360 km/s. Total magnetic field was in the 2-8.5 nT range
with Bz variable. The magnetic field phi angle was in the negative sector.
Solar wind may become somewhat enhanced again tomorrow under the possible
influence of the coronal hole that passed central meridian midnight January
12/13.

Geomagnetic conditions were quiet to unsettled (local K Dourbes and NOAA Kp
1-3).
Quiet to unsettled conditions are expected over the next days with a
possibility for an isolated active period.
TODAY'S ESTIMATED ISN  : 000, BASED ON 14 STATIONS.

Details

The SIDC ursigram starts with the code SIDC URSIGRAM YMMDD, where
Y is the last digit of the year number,
MM is the number of the month,
DD is the day of the month.
Besides the ISES codes like UMAGF, UCOSE and USSPS,
this message contains a forecast 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.
