SIDC SOLAR BULLETIN 24 Jun 2019, 1230UT
SIDC FORECAST (valid from 1230UT, 24 Jun 2019 until 26 Jun 2019)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 24 Jun 2019  10CM FLUX: 067 / AP: 005
PREDICTIONS FOR 25 Jun 2019  10CM FLUX: 068 / AP: 010
PREDICTIONS FOR 26 Jun 2019  10CM FLUX: 068 / AP: 009
COMMENT: Solar activity is very low and during last 24 hours there was no
C-class or even B-class flares reported. We expect such a low level of the
flaring activity to persist in the coming hours.
There were no Earth directed CMEs reported and the solar protons remained
at the background level.

The Earth is presently inside the slow solar wind with the speed of about
320 km/s. The interplanetary magnetic field magnitude amounts about 5 nT.
The fast solar wind associated with the patchy negative polarity coronal
hole, apparently connected to the southern polar coronal hole (which
reached central meridian on June 21), is expected to arrive to the Earth on
June 25. The geomagnetic conditions are presently quiet, and we expect such
a geomagnetic conditions to continue in the coming hours. Due to expected
arrival of the fast solar wind, unsettled geomagnetic conditions might be
expected late on June 25.

TODAY'S ESTIMATED ISN  : 012, BASED ON 23 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.
