Incoming Geomagnetic Storm Alert:C7-Flare/CME (June 21st, 2011).

June 21, 2011 Comments off

INCOMING: Magnetic fields above sunspot complex 1236 erupted during the early hours of June 21st, producing a C7-class solar flare and a full-halo CME. The expanding cloud appears to be heading almost directly toward Earth:

This does not appear to be an especially powerful CME. Nevertheless, the incoming cloud could trigger polar geomagnetic storms when it reaches Earth on or about June 23rd. The aurora outlook favors southern hemisphere observers, where solstice skies are winter-dark. Stay tuned for updates.

Cape Town – The Space Weather Centre has warned that the sun is undergoing some instability, which has implications for electronic communications.

“There is a very active area on the sun as rotated onto the invisible solar disc. This active area has got the potential for more flaring for the next five to six days,” space weather forecaster Kobus Olckers of the Space Weather Warning Centre at the Hermanus Magnetic Observatory told News24.

He said that communications and electronic systems might be affected.

“The internet could be a little slower for the next week or so and especially long distance communications.”

Strong geomagnetic storm slams Earth on Wednesday

(TheWeatherSpace.com) — A solar storm is in progress right now with the highest Kp-index in a while being recorded.

The solar storm has a Kp-Index of 6, out of the 0-9 scale. This is higher than any previous solar storms, including the March event. What caused this without a flare?

“This solar storm is likely a flare caused storm,” TheWeatherSpace.com Senior Meteorologist Kevin Martin said. “It may not have been Earth directed but a blast from the sun a couple days ago hurled a lot of material into space. This material sometimes does not follow a straight line, but can curve with the influence of magnetic fields and gravity.”

Mid and High latitude observer should check out the skies and see if the northern and southern lights are around.

Martin is the scientist that thinks solar storms are triggers to earthquake activity. Will it cause a large quake? Time will tell but enjoy the skies for the next nine hours if it is clear, dark, and you are in a higher latitude.

Get ready for a ‘global Katrina’: Biggest ever solar storm could cause power cuts which last for MONTHS

www.dailymail.co.ukImminent: The world got a taster of the sun's explosive power last week with the strongest solar eruption in five years sent a torrent of charged plasma hurtling towards the world. Scientists believe we are overdue a ferocious solar storm

  • Earth is overdue a solar storm as the sun enters its most active period.

The world is overdue a ferocious ‘space storm’ that could knock out communications satellites, ground aircraft and trigger blackouts – causing hundreds of billions of pounds of damage, scientists say.

Astronomers today warned that mankind is now more vulnerable to a major solar storm than at any time in history – and that the planet should prepare for a global Katrina-style disaster.

A massive eruption of the sun would save waves of radiation and charged particles to Earth, damaging the satellite systems used for synchronizing computers, airline navigation and phone networks.

NASA: Huge Solar Flare Jamming Radio And Satellite Signals, Could Affect Electric Grid, Bright Auroras Expected

February 17, 2011 Comments off

According to NASA, a large solar eruption triggered a giant geomagnetic storm that has disturbed radio communications and could disrupt electrical power grids, radio and satellite communication in the next days

The calm before the storm. Three CMEs are enroute, all a part of the Radio Blackout events on February 13, 14, and 15 (UTC). The last of the three seems to be the fastest and may catch both of the forerunners about mid to late day tomorrow, February 17. Watch this space for updates on the impending — G2, possibly periods of G3 — geomagnetic storming.
Watch Today’s Space Weather for the most recent activity.

A strong wave of charged plasma particles emanating from the Jupiter-sized sun spot, the most powerful seen in four years, has already disrupted radio communication in southern China.

Huge coronal hole on Sun turning towards Earth

February 3, 2011 1 comment

CORONAL HOLE: A dark croissant-shaped hole has opened up in the sun’s atmosphere, and it is spewing a stream of solar wind into space. NASA’s Solar Dynamics Observatory took this picture of the vast opening during the early hours of Jan. 30th. Researchers call this a “coronal hole.” Solar rotation is turning the coronal hole toward Earth. The stream of solar wind pouring from it will swing around and hit our planet in early February, possibly sparking polar magnetic storms. High-latitude sky watchers should be alert for auroras between Feb. 2nd and 4th. The coronal blast from the Sun storm’s arrival on Earth will coincide with a massive snow storm that will sweep across North America.  –Space Weather

Northern Lights Could Be Seen In Florida as Poles Shift

It may soon be that compasses are no longer accurate, the North Star could be the South star, and Santa just may be lost.

Don’t blame anyone just yet— the “North Pole” is merely changing.

The change is so critical, workers at two Florida airports are making changes to the Tampa International Airport and Peter O. Knight Airport. Robert Burr of TIA said one runway, number 36, pointed North at 360 degrees. But now, that same runway points 10 degrees north. TIA decided to repaint the numbers on the runway to match the pilot compass readings. Runway number 36 is now number 1.

Chris Connor, Ph.D., a Volcanologist with the University of South Florida, said that there’s a magnetic pole which is produced by changes and or flow of iron in the core of the earth. Connor said the constantly moving molten iron creates a magnet on a planetary scale with a magnetic North and South Pole. He also said that the magnetic fields have been moving— what used to be in northern Canada is now in northern Siberia.

The last shift was more than 700,000 years ago, and some experts are saying it’s time for the change. Every million years or so Earth’s magnetic pole does a flip, and new poles arise in random places. After the poles are settled, South may be the new North and vice versa. Meaning that maybe the Aurora Borealis could be seen in Florida.
