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

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

Large fractures observed in the Arctic sea ice

Large fractures in the sea ice were observed off the north coast of Alaska and Canada, from near Ellesmere Island in the Canadian Arctic to Barrow in Alaska, during the end of February and continuing into early March.According to the National Snow and Ice Data

Dust storm worsen air pollution problems in China

Dust storm worsen air pollution problems in China

The dust plumes originated from the Gobi Desert arose along the China-Mongolia border on March 8, 2013. Arising along the border between China and southwestern Mongolia, the dust extended as far south as the Sichuan Basin and continued to blow for several

Minor geomagnetic activity expected at high latitudes

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
