SIDC SOLAR BULLETIN 24 Mar 2017, 1230UT
SIDC FORECAST (valid from 1230UT, 24 Mar 2017 until 26 Mar 2017)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 24 Mar 2017  10CM FLUX: 074 / AP: 009
PREDICTIONS FOR 25 Mar 2017  10CM FLUX: 074 / AP: 007
PREDICTIONS FOR 26 Mar 2017  10CM FLUX: 074 / AP: 008
COMMENT: In the past 24 hours, no C flares were observed. Very low solar
activity (no C flares) is expected in the next 24 hours.
Over the past 24 hours, solar wind speed measured by DSCOVR varied between
about 530 and 750 km/s, while the magnitude of the Interplanetary Magnetic
Field (IMF) ranged between about 1 and 11 nT. Bz was never below -5 nT.
Quiet geomagnetic conditions (K Dourbes between 1 and 2; NOAA Kp between 1
and 3) were registered in the past 24 hours. Quiet to unsettled levels (K
Dourbes < 4) are expected on March 24, with a chance for active (K Dourbes
= 4) intervals. Quiet to unsettled geomagnetic conditions (K Dourbes < 4)
are expected on March 25 and 26.
TODAY'S ESTIMATED ISN  : 012, BASED ON 13 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.
