NASA's solar dynamics observation satellite measurements to five years of the most violent
solar radiation outbreak, arrived in earth can cause moderate geomagnetic storms, influence on
earth satellite communication and power supplies. According to the observation of solar
dynamics observation satellite, aside from a small radiation storm outside, the sun eruption
coupled with a flare and a halo material eruption.
The national weather service space weather prediction center project coordinator Cardiff, bill
mourinho tower said: "this time the outbreak started very dramatic." He pointed out that
medium solar flare in 6 at 1am edt 41 points (the GMT at 5 a.m. 41 points) peak. "We first
observed flare scale doesn't big, in the ensuing eruption process, we observed high-energy
particle radiation and large-scale halo material eruption. Can you observed out from the sun
all the material, the surface is very spectacular sight."
The sun dynamics observation satellite launched in 2010, filming the sun outbreaks of high-
definition pictures and video. According to the observation, the sun eruption in visually
spectacular, because of the earth, not positive influence on the earth can be very small. NASA
said in a statement: "rising particle formation huge mushroom, then fell back to the sun to
the surface, seems covered nearly half of the sun to the surface."
Randolph points out, intentions space weather analysts are eyeing the sun eruption, to
determine whether it leads to the sun and earth happened between magnetic field collide. Sun
in about 150 million km distance to the left. He said in an interview with the French media:
"part of our job is to monitor the sun and determine whether an outbreak of substance is
flying to the earth, because the material basically is jet with gas and magnetic. In a day or
two, we will see time some of the substance in the sun injection effect, form the earth. We do
not believe that geomagnetic storms this will be a very severe geomagnetic storms, but
strength can still reach the medium level."
Space weather prediction center, said the sun eruption triggered in 8 small to medium-sized
geomagnetic storms, from about the GMT 18 PM. Any geomagnetic storms activities will end in 24
hours. The national weather service said: "the sun radiation during the storm there are lots
of high-energy protons, this type of activity since since December 2006 was the first
observed."
A total of 12 satellite and spacecraft to the moon, NASA surveillance sunlight layer survey of
the instrument to be able to carry the orbiter to radiation that can be measured and analyzed
the influence of. Radiation effects cosmic ray telescope (CRaTER) project chief researcher Hal
orchid spencer said: "CRaTER task two years ago, this is starting to see the most important
event. This is an exciting moment. Ironically, in planning this task, we originally thought
should be in the sun, because acuteness activity peaks launch the solar particles activities
usually in this period. In fact, we in the sun, and the sun tiny period launch activities will
take a long time to revive. This is an interesting and important moment, because all the signs
are that the sun was back to active state."
The sun from an outbreak of geomagnetic storms on earth will affect some of the grid, global
positioning systems use satellites and other equipment, but also will lead to fly over the
polar regions of the flights are over to change course. He said: "normally would not cause
greater destruction, threat within the scope of the controllable. If by jet to Asia, from the
United States over the arctic, you'll find ten flights. Every day is like this. When massive
radiation storm, some airlines will because of safety concerns to change course, away from the
flight to ensure flight polar regions keep communications smooth. The company will also
operating satellites close attention, because geomagnetic storms will in various ways to
interfere with satellite and received signal receiver." NASA says, in 8 evening and 9, polar
regions may also observed aurora borealis and aboard.

.Forecast...
Solar activity is expected to remain low for the next three days (16 -
18 Aug) with a chance for M-class activity (R1-R2 Radio Blackouts).
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux at geosynchronous orbit was at
normal levels. The greater than 10 MeV proton flux at geosynchronous
orbit was at background levels.
.Forecast...
The greater than 2 MeV electron flux at geosynchronous orbit is expected
to be at normal to moderate levels, with a chance for high levels, for
the next three days (16 - 18 Aug). The greater than 10 MeV proton flux
at geosynchronous orbit is expected to be at background levels for the
next three days (16 - 18 Aug).
Solar Wind
.24 hr Summary...
Solar wind measurements at the ACE spacecraft were consistent with
coronal hole high speed stream (CH HSS) conditions as Earth remained
under the influence of (-) CH54. Winds speeds began the period at around
475 km/s and remained steady at this speed through about 15/1130 UTC. A
gradual rise was then observed to about 600 km/s through 15/1845 UTC
where speeds remained steady through the end of the period.
Interplanetary magnetic field (IMF) Bt varied between 4 nT and 11 nT
while the Bz component of the IMF varied between +11 to -9 nT. Phi was
in a predominately negative (toward) orientation through about 15/1000
UTC when it became variable between negative and positive (away).
.Forecast...
Solar wind conditions should continue to reflect CH HSS effects for the
next two days (16 - 17 Aug). Peak speeds are forecast to be in the 550
km/s to 600 km/s range as the bulk of CH54 becomes more geoeffective. By
day three (18 Aug), solar wind speeds are expected to slowly decrease as
CH HSS effects began to wane.
Geospace
.24 hr Summary...
The geomagnetic field was at quiet to active levels due to CH HSS
effects.
.Forecast...
The geomagnetic field is expected to be at quiet to unsettled levels
with isolated active periods on day one (16 Aug) as CH HSS effects
persist. Quiet to unsettled conditions are expected on day two (17 Aug)
becoming mostly quiet on day three (18 Aug) as CH HSS effects wane
