Evacuations Underway In California As Fire Rages Along The Highway


canyonfire


Corona, California is experiencing burning hillsides near a freeway as the Canyon fire rages on.  So far, the fire has forced people to quickly evacuate their homes.



The fire has destroyed more than 1,700 acres of land near Chino Hills State Park, California, with emergency crews urging people to evacuate all homes and schools in the area. The canyon fire began close to Freeway 91 just after 1 pm on Monday and has now spread to over 2,000 acres, according to the Orange County Fire Authority.





The blaze, which is only 5 percent contained, according to the fire service’s latest updates, has necessitated the use of aircraft and more than 300 firefighters.  Four schools have been closed due to the threat from the flames, with Corona City authorities urging people to leave their homes south of Green River Road to the Trudy Way area.


An evacuation shelter has been opened at the Corona High School gymnasium.







Safety precautions need to be at the forefront as the fire is now burning dangerously close to the 91E Freeway.

NASA: "Sun Erupts With Significant Flare"

Around 12:06 p.m EDT on Sept 10, 2017, NASA’s Solar Dynamics Observatory captured an image of the sun unleashing a massive solar flare from a recently active region. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth"s atmosphere to physically affect humans on the ground, however — when intense enough — they can disturb the atmosphere in the layer where GPS and communications signals travel.  Per NASA,





This flare is classified as an X8.2-class flare. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc.  



The X9.3 flare was the largest flare so far in the current solar cycle, the approximately 11-year-cycle during which the sun’s activity waxes and wanes. The current solar cycle began in December 2008, and is now decreasing in intensity and heading toward solar minimum. This is a phase when such eruptions on the sun are increasingly rare, but history has shown that they can nonetheless be intense.



This flare is the capstone on a series of flares from Active Region 2673, which was identified on Aug. 29 and is currently rotating off the front of the sun as part of our star’s normal rotation.



The flare was captured in the following NASA’s Goddard Space Flight Center video.



NASA’s Solar Dynamics Observatory captured this image of the solar flare:



The flare as seen in the bright flash on the right side on Sept. 10, 2017.


More details:





The National Oceanic and Atmospheric Administration signals X8.2 (R3-STRONG) X-RAY EVENT OBSERVED AT 10/1606 UTC. Primary areas impact includes ‘large portions of sunlit side of earth’. Possible effects include wide spread HF radio blackouts and navigation degradation through GPS (loss in signal).




As SWL.com notes, "yesterday"s X8.2 (R3-strong) solar flare from sunspot region 2673 was one of the most spectacular solar flares we have ever seen. Not only was this the second strongest solar flare of the current solar cycle, it also launched an extremely fast and broad coronal mass ejection:





Following the flare, we quickly reached the strong S3 solar radiation storm level which only takes place about 10 times during a 11 year solar cycle. Possible effects of the ongoing S3 solar radiation storm are: degraded HF radio propagation at polar regions and navigation position errors, satellite effects on imaging systems and solar panel currents, significant radiation hazard to astronauts on extra-vehicular activity (EVA) and high-latitude aircraft passengers.



The coronal mass ejection is as far as we can remember one of the fastest coronal mass ejections of the current solar cycle as we measured the ejecta at a whopping 2,700km/s to 2,800km/s! To compare: The X28 coronal mass ejection from 4 November 2003 left the Sun at 2,400km/s! Goes to show this is an extreme coronal mass ejection that would without a doubt cause intense geomagnetic storming if it would have been launched directly at Earth.



SOHO/LASCO imagery shows an impressive asymmetrical full halo coronal mass ejection which means the outer edges of the solar plasma cloud are directed straight at (or away) from the observing space craft. It is therefor hard to say if this edge is directed towards the front side, the far side or both but taking into account the monstrous coronal wave and the jump in the low-energy EPAM protons, we are fairly confident that we are going to see at least a shock passage or a glancing blow at Earth. You can see the coronal wave in the tweet that we posted yesterday.





As SWL adds, while the flanks of a coronal mass ejection are always a bit slower than the bulk, the transit time should still be around one and a half day or about 36 to 40 hours (calculated with SARM) which puts the expected impact time of this coronal mass ejection at 06:00 UTC on 12 September 2017 with a plus/minus of 6 hours. The NOAA SWPC has a much later impact time, late on September 13.


Subsequent coronagraph imagery analysis has been concluded. The full halo coronal mass ejection (CME) was so powerful and widespread, there actually appears to be an Earth directed component, most evident when viewing the LASCO C3 (blue color) video. If so, an impact to the earth"s geomagnetic field may be possible as soon as tomorrow.



According to the latest tracking models, the edge of the large CME may deliver a glancing blow to our geomagnetic field by Sept. 13th. This combined with an anticipated coronal hole stream may help to enhance activity. A Moderate (G2) storm watch will be in effect.

Huge Solar Flare Sparks Widespread Blackouts, May Deter Korean Missile Launch This Weekend

The sun just released a massive solar flare.



In fact, as SHTFplan.com"s Mac Slavo details, this is the largest solar flare emitted in the past decade, and the earth has already been affected by blackouts.


NASA has reported a huge solar flare was emitted by the Sun and it is the most powerful one since 2006 


This solar flare has already caused some radio blackouts on Earth and it may cause aurora visible as far south as London.  On the morning of September 6, scientists watched as two X-flares were unleashed by the sun.


The stronger flare was the second of the two emitted by the Sun yesterday morning and it was seen by NASA’s Solar Dynamics Observatory (SDO). At 5:10 AM EDT, the Sun unleashed an X2.2 flare, with X-class denoting the most intense flares. Then, at 8:02 AM EDT, a much bigger flare measuring X9.3 was unleashed. By comparison, the last time we saw a flare this big was in 2006, which measured at X9.0. The number shows the intensity, with X2 being twice as intense as X1, X3 three times as intense, and so on.


The loops of plasma emitted during these two flares were ten times the size of planet Earth. Scientists got to watch the massive coronal mass ejection from these flares, which can be seen below in the gif provided.

According to NASA, the flares were emitted from an active region of the Sun known as AR 2673. This region also emitted a mid-level flare on September 4, 2017. But scientists say the timing of these big flares is rather odd as the Sun is currently heading towards the quieter period of its 11-year solar cycle known as solar minimum. This cycle began in 2008, with solar minimum expected in the next couple of years.



“This is a phase when such eruptions on the Sun are increasingly rare, but history has shown that they can nonetheless be intense,” said NASA.


And this one had some effects on life on Earth.  It knocked out the high-frequency radio, according to the NOAA, and degraded low-frequency navigation. But the Space Weather Prediction Center (SWPC) said it was expecting some radio blackouts yesterday, and the high-frequency radio was expected to drop out for an hour.


The particles from the CME (coronal mass ejection) can also cause aurora activity further south than normal as they interact with Earth’s magnetosphere.

*The map above shows how far south the aurora will be visible thanks to these solar flares.  If interested, watch the skies for the show.


Scientists aren’t sure yet if the CME was directed towards Earth. If it does come our way, it could cause a strong geomagnetic storm that will further hamper communications.

But there is a silver-lining to this massive solar flare.


As Bloomberg points out, North Korea could decide to delay its next ballistic missile launch because the current outbreak of severe geomagnetic storms can pose a risk to electronic equipment.


As we detailed previously, South Korean Prime Minister Lee Nak-yon said Thursday the next launch could come on Saturday, the anniversary of North Korea’s founding.


But, while missiles are generally heavily shielded against radiation, Kim Jong Un may decide not to risk firing one during the solar flares in case they lose data or ancillary equipment, said Lance Gatling, an aerospace consultant with Nexial Research in Tokyo.


He added that the U.S. and Japan might be hoping for a launch so they can test detection and tracking equipment in a storm environment.


But while that temporary cessation of North Korea"s nuclear development is positive, StockBoardAsset notes that the solar flare shows that our modern economies and societies are fragile.


There is a reason why our Government and NASA are preparing as highlighted in the recent Exec Order.



This week"s X-9 solar flare - the largest in a decade should serve as a reminder how close we really are to the edge. At the same time, a Hurricane in the Atlantic called Irma strengthens to a CAT-5 with winds near 185mph spiraling towards Florida. Perhaps, the sun and earth are more interconnected than we think as junk science called global warming distracts the true understanding of how nature works.
