SIDC SOLAR BULLETIN 29 Jun 2016, 1240UT
SIDC FORECAST (valid from 1230UT, 29 Jun 2016 until 01 Jul 2016)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 29 Jun 2016  10CM FLUX: 073 / AP: 005
PREDICTIONS FOR 30 Jun 2016  10CM FLUX: 070 / AP: 009
PREDICTIONS FOR 01 Jul 2016  10CM FLUX: 068 / AP: 008
COMMENT: There are no active regions presently observed on the visible side
of the solar disc, and there was no C-class flares, (only one low B-class
flare) reported during last 24 hours. We expect solar activity to remain
low.
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 400 km/s. The interplanetary magnetic field is stable with the
magnitude of about 4 nT. The geomagnetic conditions are quiet and are
expected to remain so in the coming hours. The elongated equatorial coronal
hole (between N10 to S25), has crossed central meridian early this morning.
The associated fast solar wind might arrive at the Earth in the early
morning of July 2, and induce unsettled to active geomagnetic conditions.

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.
