SIDC SOLAR BULLETIN 27 Jun 2016, 1230UT
SIDC FORECAST (valid from 1230UT, 27 Jun 2016 until 29 Jun 2016)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 27 Jun 2016  10CM FLUX: 077 / AP: 012
PREDICTIONS FOR 28 Jun 2016  10CM FLUX: 079 / AP: 013
PREDICTIONS FOR 29 Jun 2016  10CM FLUX: 080 / AP: 021
COMMENT: Solar activity is low with no C-class flares reported during last
24 hours. Strongest reported flare was B5.8 flare which peaked at 09:58 UT
today. We expect solar activity to remain low. The isolated low C-class
flare is possible, although not very probable. No Earth directed CMEs were
observed in the last 24 hours.
The Earth is currently inside a slow solar wind flow with the speed of
about 460 km/s. The interplanetary magnetic field is stable with the
magnitude of 5 nT. The geomagnetic conditions are quiet and expected to
remain so in the coming hours.
The fast solar wind associated with the elongated equatorial coronal hole,
which reached central meridian in the early morning of June 26, is expected
to arrive in the late evening of June 28, and it might induce unsettled to
active geomagnetic conditions. The ALL-QUIET-ALERT will be therefore
canceled.

TODAY'S ESTIMATED ISN  : 000, BASED ON 14 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.

A forecast is given on:
the global flare probability,
geomagnetic disturbances,
solar proton events.
