SIDC SOLAR BULLETIN 19 Jul 2018, 1230UT
SIDC FORECAST (valid from 1230UT, 19 Jul 2018 until 21 Jul 2018)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 19 Jul 2018  10CM FLUX: 071 / AP: 008
PREDICTIONS FOR 20 Jul 2018  10CM FLUX: 070 / AP: 012
PREDICTIONS FOR 21 Jul 2018  10CM FLUX: 069 / AP: 008
COMMENT: There are presently no sunspot groups observed on the visible side
of the Sun, and accordingly there was no flaring activity during last 24
hours. No Earth directed CMEs were observed, and the solar protons remained
at the background level.

The Earth is still inside the slow solar wind with the speed of about 370
km/s. The interplanetary magnetic field magnitude is  presently 4 nT.
The increase of the solar wind speed, associated with patchy equatorial
coronal hole that reached central meridian on July 16, might be expected in
the morning of July 20. The unsettled to possibly, but not very probably,
short interval of active conditions might be induced with the expected
arrival of the fast solar wind.

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.
PREDICTIONS FOR "today" : 10CM FLUX: xxx / AP: xxx

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.
