SIDC SOLAR BULLETIN 18 Jul 2018, 1230UT
SIDC FORECAST (valid from 1230UT, 18 Jul 2018 until 20 Jul 2018)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 18 Jul 2018  10CM FLUX: 071 / AP: 006
PREDICTIONS FOR 19 Jul 2018  10CM FLUX: 071 / AP: 007
PREDICTIONS FOR 20 Jul 2018  10CM FLUX: 070 / AP: 012
COMMENT: Solar activity remains to be at very low level, and there were no
flares reported during last 24 hours. As there are no active regions
present at the visible side of the Sun, we expect such a low flaring
activity to persist in the coming hours.
No Earth directed CMEs were observed during last 24 hours, and the solar
protons remained at the background level.

The increase of the solar wind speed, associated with patchy equatorial
coronal hole that reached central meridian on July 16, is expected at the
Earth late on July 19. The unsettled to possibly, but not very probably,
active conditions are expected in the morning of July 20, due to the
expected arrival of the fast solar wind.
The geomagnetic conditions are presently quiet, and we expect them to stay
so in the coming hours.

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.
