Mars-Bound Instrument Detects Solar Burst's Effects: RAD Measures Radiation from Solar Storm
January 27, 2012 — The largest solar particle event since 2005 hit Earth, Mars and the Mars Science Laboratory spacecraft traveling in-between, allowing the onboard Radiation Assessment Detector to measure the ... > full story -
Classifying Solar Eruptions
January 25, 2012 — Solar flares are giant explosions on the sun that send energy, light and high speed particles into space. These flares are often associated with solar magnetic storms known as coronal mass ejections ... > full story -
Space Weather Arrives: Relatively Minor Impacts Expected from Solar Storm
January 24, 2012 — A significant blast of energy from the sun arrived at Earth on Jan. 24, 2012 at 10 a.m. EST, triggering a moderate geomagnetic storm here that's unlikely to cause major problems. But skywatchers take ... > full story -
Strongest Solar Radiation Storm Since 2005
January 23, 2012 — NOAA's Space Weather Prediction Center -- the nation's official source of warnings and alerts about space weather and its impacts on Earth -- has issued a watch for a geomagnetic storm associated ... > full story -
Magnetic Pole Reversal Happens All the (Geologic) Time
November 30, 2011 — Scientists understand that Earth's magnetic field has flipped its polarity many times over the millennia. The answer, from the geologic and fossil records we have from hundreds of past magnetic ... > full story -
2012: Killer Solar Flares Are a Physical Impossibility, Experts Say
November 11, 2011 — 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 ... > full story -
Space Weather Prediction Model Improves Forecasting
October 20, 2011 — NOAA is now using a sophisticated forecast model that substantially improves predictions of space weather impacts on Earth. Better forecasts offer additional protection for people and the ... > full story -
Strong Solar Storm Reaching Earth
September 26, 2011 — NOAA's Space Weather Prediction Center -- the nation's official source of warnings and alerts about space weather and its impacts on Earth -- issued a warning for a strong, G3 geomagnetic storm on ... > full story -
Sunspot 1302 Continues to Turn Toward Earth
September 26, 2011 — A strong-to-severe (Kp=8) geomagnetic storm is in progress following the impact of a coronal mass ejection (CME) at approximately 8:15a.m. EDT (12:15 UT) on Sept. 26. The Goddard Space Weather Lab ... > full story -
Solar Activity Can Affect Re-Entry of UARS Satellite
September 23, 2011 — The Upper Atmosphere Research Satellite (UARS) is headed toward Earth, but it hasn't been easy to precisely determine the path and pace of UARS because space itself changes over time -- in response ... > full story
