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.

Possible Events of 12, 21, 2012


The Hoppis Miyans recognize that we are approaching the end of a cycle and the beginning of a new cycle, in 12, 21, 2012. In all cases, however, the Hopisand Meyans shaman do not think that everything will come to an end. Rather, this is a time of transition from one World Era into another. The message they give concerns our making a choice of how we view the future ahead. Our moving ahead with either resistance or acceptance may determine whether the transition will happen with Horrific changes or gradual peace and tranquility when 12, 21, 2012 happens. The same time line can be found reflected in the prophecies of many other indigenous peoplesvisionaries from earlier times . |Amazingly, there is a cultural/prophetic context for the arising of this Feminine-based planetary change that is underway. The 12, 21, 2012 foretelling foretold of this shift of worldly stewardship into the hands of the Feminine. |We are living today in the cusp of the many cultural predicted end times, the end of a galactic day or time period spanning thousands of years. |The precise Cycle of the Mayan Long Count calendar ends on the winter solstice of 12, 21, 2012 A.D. Following the concepts of cyclic time and (Earth|World|Planet} Age transitions, this is as much about beginnings as the ending. In fact, it was considered by the ancient Mayans to signify the creation of a new (Earth|World|Planet} Age. We are almost at the end of the fifth and final age!|Common expectations concerning the Solstice on 12, 21, 2012 range from spiritual enlightenment to disastrous events, though no single point of factual basis is a tell tale sign. Despite a decisive lack of indicators for Apocalyptic events are in any reliable calendar or mathematical system, that points to an end of 12,21.2012. 

 What is to come in 2012? What is the real concern with solar activity and the magnetic poles? What do we have to fear from our own home world and the star which sustains life on our planet?
The answers to these questions are alarming and devastating. All my deciphering points to a complex and ingenious science. Let me explain. When you, as a scientist, stumble upon results that the present astronomers do not know, you have, without doubt, stumbled upon something terribly important. Everybody will have to admit it, and that is exactly what I have done: I discovered an echo of a long-lost technological terminology; a majestic building with immensely sophisticated keys. Many numbers were based on the sunspot cycle, which they had discovered. A theory that is irrefutably correct and not known by our physicists! It cannot be more alarming!

Latest Solar Flare News May 17 2012

Just as we thought we have seen the last of Sunspot 1476, the former active region decided to produce a solar flare reaching above the M5.0 level. The GOES Solar X-Ray data did show M4.6 before it stopped reporting at 01:43 UTC Thursday morning. SDO/EVE data suggests it may have been closer to M8.0. Because of the sunspots location, any possible CME may be directed mostly away from Earth.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 137 Issued at 2200Z on 16 May 2012

IA.  Analysis of Solar Active Regions and Activity from  15/2100Z
to 16/2100Z:  Solar activity was low. Region 1476 (N13W73) produced a
few C-class flares while continuing to decay. Regions 1482 (N13E10)
and 1484 (N09E38) also produced a few low level C-class events. A
pair of CMEs associated with apparent filament eruptions were
observed in LASCO C2/C3, but neither appear to be earth directed.

IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low for the next 3 days (17-19 May).

IIA.  Geophysical Activity Summary 15/2100Z to 16/2100Z:
The geomagnetic field was mostly quiet. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels during the
period.

IIB.  Geophysical Activity Forecast:  With the exception of an
isolated unsettled or active period early on day 1 (17 May) from an
expected solar sector boundary crossing, geomagnetic field
conditions are expected to be mostly quiet throughout the period
(17-19 May).

Solar and Geophysical Activity Report of 07Mar 2012

An X-1.1 class solar flare erupted from the Sun on Sunday, March 4 at 11:13 PM EST (0413 UTC March 5), sending an explosion of plasma and charged particles -- a coronal mass ejection (CME) -- hurtling through space. Forecasters at NOAA’s Space Weather Prediction Center (SWPC) are saying that the CME should miss Earth, but will hit Mercury and Venus.
Even if this CME misses, high-latitude sky watchers should still be alert for auroras in the nights ahead. An M3-class eruption from the same sunspot just a day before produced another, wider CME that might intersect Earth. The cloud is expected to deliver a glancing blow to Earth’s magnetic field on March 6 around 0430 UTC. Sunday night’s solar flare is only the second X-class eruption so far this year. X-class flares are the most powerful type of solar storm; M-class eruptions are considered midrange and C-class flares are the weakest.
According to Spaceweather.com, SWPC forecasters are estimating a 75 percent chance of M-class solar flares and a 30 percent chance of an X-flare from big sunspot 1429, which emerged on the Sun on March 2 and is estimated to be at least four to five times larger than Earth. The active region is slowly turning to face Earth, so if any such eruptions do occur, they are increasingly likely to be geoeffective. Forecasters say there is a 30-40 percent chance of polar geomagnetic storms through the rest of the week. The 1429 sunspot region continues to be quite active since it emerged on March 2, and scientists are predicting it will spew more flares as the week goes on.
When a CME hits the Earth’s atmosphere -- approximately 72 hours after exploding on the Sun -- the low bands will be depressed and signals will be weaker the lower the frequency. The absorption rate will be most severe on 160 meters, less on 80 and somewhat better on 40 meters. The maximum usable frequency (MUF) -- the highest frequency by which a radio wave can propagate between given terminals by ionospheric propagation alone, independent of power -- will be lower and auroral propagation on the VHF bands is quite possible.
When aurora occur, the electrons hit the ionosphere at the North and South geomagnetic poles, creating ionization. Waves that would normally travel off into space are bouncing off the aurora and being redirected back toward Earth. This can create opportunities for long-distance propagation via VHF and UHF.
VHF operators greet CMEs as a welcome opportunity for unusual, enhanced propagation. “CMEs can trigger the Aurora Borealis,” explained ARRL Contest Branch Manager and VHF aficionado Sean Kutzko, KX9X. “If the aurora is intense enough, you can use it as a ‘wall’ to bounce signals off of on 6 and 2 meters -- and sometimes higher. If you have a beam on the VHF bands, point it north (or south, if you’re in the Southern Hemisphere) and listen for strange-sounding signals.”
Kutzko noted that aurora can cause audio signals to become very distorted: “On 6 meters, SSB signals become quite difficult to understand, and on 2 meters, it renders sideband practically unusable. CW is the preferred mode of communication during an aurora opening. Even so, the pure tone of a CW signal becomes distorted as well, reducing the pure ‘beep’ tone to a whisper-like ‘pffft.’”
In 2013, solar activity levels are expected to peak with the next solar maximum within the 11-year solar activity cycle. “We now know how powerful space weather can be and how events that begin on the surface of the Sun can end up wreaking havoc here on Earth,” said SWPC Director Tom Bogdan. “This is why NOAA has a Space Weather Prediction Center -- to forecast when space weather is coming our way, so we can avoid or mitigate damages. We’re coming up to the next solar maximum, so we expect to see more of these storms coming from the Sun over the next three to five years.”
