• Moderate solar flare measuring M2.2 erupted on April 5, 2013

    A moderate solar flare measuring M2.2 erupted on April 5, 2013. The event peaked at 17:48 UTC. The source of this solar flare appears to be old Region 1695 located near the northeast limb. This region is just coming into Earth view. Earth side of the Sun was

  • Farside active region shoots bright CME toward Venus

    An active region in the Sun’s far-southern hemisphere erupted on March 23, 2013 around 13:00 UTC hurling bright Coronal Mass Ejection (CME) toward the Venus. A glancing impact is expected on March 25th. Venus has no global magnetic field to protect it from CME’s so the

  • M1.6 solar flare erupted at western limb

    Impulsive M1.6 solar flare erupted from the Active Region 1692 on western limb. Moderate event started at 21:58 UTC and reached peak of M1.6 at 22:04 UTC. SDO’s EVE soft X-ray monitor on the left and SWPC’s X-ray flux monitor on the right show M-class signature

  • 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

  • Strong CME impact – G2 Geomagnetic Storm

    Long duration M 1.2 solar flare erupted on March 15, 2013 and launched a Full-Halo Coronal Mass Ejection (CME) toward Earth. It hit Earth’s magnetic field at 06:01 UTC on March 17, 2013 and Geomagnetic K-index of 6 reached threshold on March 17, 2013 at 08:42

  • Long duration M1.2 solar flare, Full-Halo Earth directed CME

    Region 1692 erupted with long duration M-class solar flare peaking at 06:50 UTC as M1.2 solar flare on March 15, 2013. The event started at 05:52 and ended at 07:30 UTC. A Full-Halo Coronal Mass Ejection (CME) was observed and it looks to be Earth directed.A 10cm

  • Minor geomagnetic activity expected at high latitudes

    On March 12, 2013 a solar filament in the sun’s northern hemisphere erupted and launched Coronal Mass Ejection (CME). The source of the explosion was active region AR1690. A CME produced by the explosion is traveling north of the Earth line, but part of the CME

  • Long duration C2 solar flare erupted from Region 1690

    A long duration C-class solar flare erupted from Region 1690 on March 12, 2013. The event started at 10:17, peaked ad 11:06 as C2.0 flare and ended at 12:25 UTC. A Coronal Mass Ejection (CME) was produced. Region 1690 still has Alpha magnetic configuration, but its

  • Researchers discovered source of solar wind energy

    Researchers have found signs of an energy source in the solar wind, a hot and fast flow of magnetized gas that streams away from the sun’s upper atmosphere. Solar wind is made of hydrogen and helium ions with a sprinkling of heavier elements. Solar wind is
