SIDC SOLAR BULLETIN 17 Nov 2018, 1230UT
SIDC FORECAST (valid from 1230UT, 17 Nov 2018 until 19 Nov 2018)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 17 Nov 2018  10CM FLUX: 072 / AP: 003
PREDICTIONS FOR 18 Nov 2018  10CM FLUX: 072 / AP: 004
PREDICTIONS FOR 19 Nov 2018  10CM FLUX: 072 / AP: 004
COMMENT: There were no flares on the visible solar disc of the Sun in the
past 24 hours. The chance for a C flare in the next 24 hours is estimated
at 10%.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in available
coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24
hours, and is expected to stay at nominal levels in the next 24 hours.

In the past 24 hours, solar wind speed near Earth as registered by DSCOVR
varied between about 315 and 365 km/s, with current values around 330 km/s.
The Interplanetary Magnetic Field (IMF) was predominantly directed towards
the Sun and its magnitude varied between about 0 and 6 nT. Bz was never
below -5 nT.

Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 0
and 1) were registered in the past 24 hours. Quiet to unsettled conditions
(K Dourbes < 4) are expected on November 17, 18 and 19.
TODAY'S ESTIMATED ISN  : 016, BASED ON 18 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.
