M5.5 Eruption / Earth Directed CME / Radiation Storm

Moderately strong M5.5 solar flare event observed around region 2673 on Monday evening.UPDATE: An update regarding the M5.5 solar flare event around region 2673 this evening at 20:33 UTC. The flare was associated with a Type II radio emission with an estimated velocity of 1472 km/s, along with a 10cm radio burst (TenFlare) lasting 52 minutes and measuring 1600 solar flux units (SFU). Low energy proton levels as measured by the GOES-13 spacecraft are currently on the rise. Updated coronagraph imagery courtesy of LASCO C3 shows a coronal mass ejection (CME) leaving the sun and at least a portion of this cloud may be Earth directed. More updates to follow. UPDATE #2 @ 00:45 UTC (Sep 5): Proton levels continue to rise following the eruption around 2673 earlier this evening. A minor (S1) radiation storm is currently in progress.

latest solar flare activity - Strong G3 Geomagnetic Storm June 22 2015

The NOAA Space Weather Prediction Center (SWPC) has issued a Strong G3 Geomagnetic Storm watch beginning tomorrow (June 22). The expected storm is the result of a full halo CME observed early Sunday morning. Sky watchers at middle to high latitudes should be alert for visual aurora during the next several days.

Solar activity during the past 24 hours was moderate. Region 2367 was responsible for the strongest X-Ray event of the period, an impulsive M3.8 flare peaking at 09:44 UTC. A noteworthy CME from this event is unlikely. The most interesting event of the past 24 hours was a dual M-Flare event around region 2371 during the early hours of June 21. An M2.0 flare was quickly followed up by an M2.6 event at 02:34 UTC.

 A full halo coronal mass ejection (CME) became visible soon after in coronagraph imagery and appears to be Earth directed. An impact to our geomagnetic field will be possible during the next 48-72 hours and could lead to geomagnetic storming at high latitudes. Additional isolated M-Flares will be possible around both regions 2367 and 2371 during the next day. Stay tuned to SolarHam.com for the latest information.

SOLAR FLARE STORM aug 16 2013

Geomagnetic Storm Watch
A solar wind stream flowing past Earth remains above 700 km/s. A brief period of minor geomagnetic storming (Kp=5) was observed early this morning at high latitudes. Additional flareups of minor storming will be possible today, particularly if the Bz/IMF component decides to tip south for an extended period of time. Stay tuned for the latest information.
UPDATE: A solar wind stream flowing from a geoeffective coronal hole remains elevated near 700 km/s heading into Friday evening and the Bz/IMF component remains fairly stable. Only minor geomagnetic disturbances (Kp=4) have been detected today so far. There will remain a chance for isolated storm conditions (Kp=5) at high latitudes tonight. Be on the lookout for visible aurora should geomagnetic conditions allow.

Solar activity is currently low with only minor B-Class activity detected within the past 12 hours and an impulsive C1.3 flare moments ago at 12:47 UTC around Sunspot 1818. Both regions 1817 and 1818 have a Beta-Gamma-Delta magnetic configuration. There will remain a chance for C-Class flares and perhaps an isolated M-Class event. A small eruption registering as a C2.9 solar flare Thursday evening to the west of 1817 generated a faint Coronal Mass Ejection (CME) now visible in the updated Lasco C2 imagery. It does not appears to be Earth directed.
UPDATE: 1817 again appears to be weakening, but 1818 retains a delta configuration and is currently producing impulsive C-Class solar flares.

Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 183 Issued at 2200Z on 02 Jul 2013


IA.  Analysis of Solar Active Regions and Activity from 01/2100Z to
02/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C7 event observed at
02/1749Z from Region 1785 (S11E62). There are currently 7 numbered
sunspot regions on the disk.

IB.  Solar Activity Forecast: Solar activity is likely to be low with a
slight chance for an M-class flare on days one and two (03 Jul, 04 Jul)
and expected to be very low with a chance for a C-class flares on day
three (05 Jul).


IIA.  Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 498 km/s at
01/2136Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 4429 pfu.

IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (03 Jul), quiet to unsettled levels on
day two (04 Jul) and quiet to active levels on day three (05 Jul).

Updated Aug 22 2200 UTC

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 235 Issued at 2200Z on 22 Aug 2012

IA. Analysis of Solar Active Regions and Activity from 21/2100Z
to 22/2100Z: Solar activity was very low. Region 1548 (N18E18)
produced the largest event of the period, a B6/Sf flare at 22/1658Z.
The remaining numbered regions were stable and quiet. A full halo
CME was observed in SOHO/LASCO C2 coronagraph imagery beginning at
21/2024Z with an estimated plane-of-sky speed of 884 km/s. STEREO-A
and STEREO-B COR2 imagery shows this CME to be a back-sided event
and is not expected to be geoeffective. SDO/AIA 193 imagery showed a
filament eruption in the vicinity of plage Region 1549 (S18W72) at
approximately 22/0930Z. A CME was subsequently observed in LASCO/C2
coronagraph imagery at 22/1012Z, and in LASCO C3 imagery at
22/1118Z. Analysis is underway to determine the potential
geoeffectiveness of this event.

IB. Solar Activity Forecast: Solar activity is expected to be very
low with a slight chance for C-class flares for the next three days
(23-25 August).

IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z:
The geomagnetic field was quiet to unsettled. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels during the
period.

IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be predominately quiet for days 1-3 (23-25 August).
