Sunspots Go Wild! X-Class Solar Flares are heading to Earth

Posted on 08 January 2014 by admin


A false-color composite image from NASA’s Solar Dynamics Observatory shows a blast of activity originating from an active sunspot region at the center of the sun’s disk on Tuesday.

The sun erupted with a powerful solar flare on Tuesday, disrupting radio traffic and sending a blast of electrically charged particles our way. And there may be more blasts to come.

The X1.2-class flare was recorded by sun-observing satellites, including NASA’s Solar Dynamics Observatory, at about 2:32 p.m. ET. X-class flares are the strongest category of solar outbursts, although X1.2 is toward the category’s low end. The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center said the flare sparked a strong radio blackout.

For days, space weather forecasters have been bracing themselves for solar eruptions from a large active sunspot region called AR1944. This region has now turned to face Earth directly, which means strong solar flares are likely to send storms of charged particles — also known as coronal mass ejections, or CMEs — heading straight for us.

Sun ‘flips upside down’ – Reverses Magnetic Field

Posted on 31 December 2013 by admin

solarstormshitearthemf2The sun has undergone a “complete field reversal,” with its north and south poles changing places as it marks the midpoint of Solar Cycle 24.

“A reversal of the sun’s magnetic field is, literally, a big event,” NASA’s Dr. Tony Phillips said in a statement issued on the space agency’s website.

“The sun’s polar magnetic fields weaken, go to zero and then emerge again with the opposite polarity. This is a regular part of the solar cycle,” Stanford solar physicist Phil Scherrer explained.

While it may seem like the event could have catastrophic repercussions for the galaxy, its effects are actually more subtle, mostly interfering with space exploration.

“Cosmic rays are a danger to astronauts and space probes, and some researchers say they might affect the cloudiness and climate of Earth,” said Phillips.

Both the aurora borealis and its southern counterpart – the australis – are set to become broader, more frequent, and more visible now that the event has reached its final stage.

Solar Storm Eruption

By Tariq Malik | – Sun, Mar 17, 2013

A massive eruption on the sun Friday (March 15) unleashed a wave of intense solar particles at Earth that may spark a geomagnetic storm and boost weekend aurora displays.

The Earth-directed solar storm occurred Friday at 2:54 a.m. EDT (0654 GMT) in what astronomers call a coronal mass ejection — or CME — a sun eruption that can release billions of tons of solar material into space. The particles typically take between one and three days to reach Earth, where they can pose a hazard to satellites and electronic systems in orbit and on the planet’s surface, NASAofficials said in a statement.

The solar particles from the Friday eruption were expected to reach Earth today (March 17).

“High-latitude and possibly even middle-latitude sky watchers should be alert for auroras this weekend,” the website, which tracks space weather and stargazing events, said in a weekend alert. [Amazing Auroras Photos of 2013]

The Friday sun eruption sent a wave of solar particles streaking toward Earth at about 900 miles per second, according to observations by NASA and European spacecraft. That is the equivalent of a mind-boggling about 3.2 million miles per hour (5.2 million km/h).

According to NASA, this “is a fairly fast speed for CMEs. Historically, CMEs at this speed have caused mild to moderate effects at Earth.”

The solar eruption should not pose a threat to satellites and spacecraft around Earth, but it may pass NASA’s Messenger spacecraft orbiting Mercury and the infrared Spitzer Space Telescope, agency officials said. NASA alerted the mission operation centers for both missions.

“There is, however, only minor particle radiation associated with this event, which is what would normally concern operators of interplanetary spacecraft since the particles can trip on board computer electronics,” NASA officials said.

An alert by the Space Weather Prediction Center operated by the National Oceanic and Atmospheric Administration reported that the Earth’s geomagnetic field could be at “unsettled to major storm levels” once the CME particles reached Earth Sunday. There was a 70 percent chance of a geomagnetic storm today, the alert added.

When the sun fires off an eruption in Earth’s direction, the charged solar particles that reach the planet are funneled to the Earth’s poles by its magnetic field. When the particles interact with the Earth’s atmosphere, they can cause a glow visible from the ground: the northern lights.

Northern lights displays over the North Pole region are known as the aurora borealis. Their southern counterpart is known as the aurora australis.

The sun is currently in the midst of an active phase of its 11-year solar weather cycle and is expected to reach its peak activity in 2013.
