• G1 (Minor) Geomagnetic Storm in progress – May 18, 2013

    G1 (Minor) Geomagnetic Storm conditions are now occurring due to the arrival of the CME from May 15, 2013. During G1 Geomagnetic Storm, weak power grid fluctuations can occur, minor impact on satellite operations is possible, aurora is commonly

  • Intro to space weather vocabulary – video

    Heliophysics scientists study energy transformation from one event to the other and which electromagnetic waves create which conditions near Earth. Space weather effects can disrupt satellites in space, so scientists need to understand the system in even more detail.

  • Corona aurora over UAF ski trail, Alaska

    Time-lapse movie of the corona aurora that appeared over UAF ski trail, Fairbanks, Alaska after strong CME hit Earth’s magnetic field. Red aurora was also captured. (1:54 – 2:32am AKST, March 17, 2013) Corona aurora is a shape of aurora in which rays

  • Geomagnetic storms – basic terms, data, plots and graphs

    A coronal mass ejection (CME) that erupted on March 15, 2013, hit Earth's magnetic field at 06:00 UTC on March 17, 2013. The solar wind speed reached 700 km/s and sparked a moderately strong G2 (Kp=6) geomagnetic storm and minor S1 solar radiation

  • CME from September 28 eruption heading toward Earth

    Sunspot 1577 generated a long duration C3.7 solar flare which hurled a coronal mass ejection (CME) almost directly toward Earth on September 28. Proton levels reached the S1 Minor Radiation Storm level soon after the event. The proton event linked to the C3.7 flare
