Magnetic Field Model Of Sun Explains Solar Activity Cycles
2013-05-23 08:32:58

April Flowers for redOrbit.com - Your Universe Online Since the 18th Century, scientists have been aware that the Sun oscillates between periods of high and low solar activity in an 11-year cycle. So far, though, they have been unable to fully explain how this cycle is generated. Understanding the Sun´s magnetic activity has become increasingly important as we rely more on our electronic devices. Changes in the magnetic field are responsible for “space weather”...

M-Class Solar Flare And Two Coronal Mass Ejections Detected Mid-Week
2013-05-23 07:00:42

Lawrence LeBlond for redOrbit.com - Your Universe Online As the peak year of the solar maximum picks up in intensity, NASA´s Solar Dynamics Observatory (SDO) observed yet another solar flare and two coronal mass ejections (CMEs) mid-week. On Wednesday May 22 the sun emitted an M7 solar flare, which peaked at about 9:38 a.m. EDT. While it was not immediately clear if the M-class flare also produced a CME, NASA confirmed later that the flare was associated with a CME. While this CME...

NASA’s BARREL Mission Released 20 Balloons To Help Answer Question About Space Weather
2013-05-21 12:07:08

NASA In Antarctica in January, 2013 — the summer at the South Pole — scientists released 20 balloons, each eight stories tall, into the air to help answer an enduring space weather question: when the giant radiation belts surrounding Earth lose material, where do the extra particles actually go? The NASA-funded mission is called BARREL for Balloon Array for Radiation-belt Relativistic Electron Losses and is led by physicist Robyn Millan of Dartmouth College in Hanover, N.H....

Coronal Mass Ejection Heads Toward Earth This Weekend
2013-05-19 07:37:21

[WATCH VIDEO: Coronal Mass Ejection On May 17, 2013] Lawrence LeBlond for redOrbit.com - Your Universe Online On May 17, the sun unleashed an Earth-directed coronal mass ejection (CME) at 5:24 a.m. EDT sending billions of tons of solar particles into space. The matter from this CME will likely reach Earth in one to three days and potentially affect electronic systems in satellites and possibly the International Space Station (ISS). NASA research models based on observations from...

Solar Activity Continues On The Sun
2013-05-15 11:28:59

NASA Solar activity continued on May 14, 2013, as the sun emitted a fourth X-class flare from its upper left limb, peaking at 9:48 p.m. EDT. This flare is classified as an X1.2 flare and it is the 18th X-class flare of the current solar cycle. The flare caused a radio blackout — categorized as an R3, or strong, on NOAA´s space weather scales from R1 to R5 -- which has since subsided. The flare was also associated with a non-Earth-directed CME. CMEs and flares are separate but...

The Impacts Of Strong Solar Flares
2013-05-14 07:53:54

NASA Given a legitimate need to protect Earth from the most intense forms of space weather -- great bursts of electromagnetic energy and particles that can sometimes stream from the sun -- some people worry that a gigantic "killer solar flare" could hurl enough energy to destroy Earth, but this is not actually possible. Solar activity is indeed currently ramping up toward what is known as solar maximum, something that occurs approximately every 11 years. However, this same solar cycle...

Mid-Level Solar Flare Emitted By The Sun
2013-05-04 08:29:41

NASA The sun emitted a mid-level solar flare, peaking at 1:32 pm EDT on May 3, 2013. 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. This disrupts the radio signals for as long as the flare is ongoing, and the radio blackout for this flare has already...

Satellite Instrument Package To Assess Space Weather Ready For Delivery
2013-05-02 15:25:32

University of Colorado Boulder A multimillion dollar University of Colorado Boulder instrument package to study space weather has passed its pre-installation testing and is ready to be incorporated onto a National Oceanic and Atmospheric Administration satellite for a 2015 launch. Designed and built by CU´s Laboratory for Atmospheric and Space Physics, the instrument suite known as the Extreme Ultraviolet and X-ray Irradiance Sensors, or EXIS, is the first of four identical...

Orbital To Build Icon Space Weather Satellite For NASA
2013-04-30 04:53:34

redOrbit Staff & Wire Reports - Your Universe Online NASA has awarded a two-year, $50 million contract to Orbital Sciences Corporation to build a new heliophysics science satellite that will investigate the connection between space weather storms in the ionosphere and Earth´s terrestrial weather. The mission is currently set to launch in 2017, and will study the interface between the upper reaches of the Earth´s atmosphere and outer space in response to a recent scientific...

NASA Mission To Study What Interferes With Radio Waves
2013-04-26 07:44:43

NASA A NASA-funded sounding rocket mission will launch from an atoll in the Pacific in the next few weeks to help scientists better understand and predict the electrical storms in Earth's upper atmosphere. These storms can interfere with satellite communication and global positioning signals. The mission, called EVEX, for the Equatorial Vortex Experiment, will launch two rockets for a twelve-minute journey through the equatorial ionosphere above the South Pacific. The launch window for...
