SIDC SOLAR BULLETIN 01 Jul 2020, 1230UT
SIDC FORECAST (valid from 1230UT, 01 Jul 2020 until 03 Jul 2020)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 01 Jul 2020  10CM FLUX: 069 / AP: 007
PREDICTIONS FOR 02 Jul 2020  10CM FLUX: 070 / AP: 007
PREDICTIONS FOR 03 Jul 2020  10CM FLUX: 070 / AP: 005
COMMENT: Only one sunspot group is presently observed on the visible side
of the solar disc. The newly emerged, Catania sunspot group 33 was the
source of several A class flares during last 24 hours. We expect a low
level of flaring activity to persist in the coming hours.
During last 24 hours there were no Earth directed CMEs and the solar
protons remained at the background level.

The solar wind speed is presently about 315 km/s, and the interplanetary
magnetic field magnitude is 4 nT. One interval of the unsettled geomagnetic
conditions was reported by local station at Dourbes (K=3), at about 09 UT
today. The geomagnetic conditions are presently quiet and we expect quiet
geomagnetic conditions in the coming hours.
TODAY'S ESTIMATED ISN  : 005, 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.
