Increased Solar Activity - X-3 flare


 On Nov. 5th at 22:12 UT, the magnetic canopy of sunspot AR1890 erupted, producing a brief but intense X3-class solar flare. NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash. Radiation from the flare caused a surge in the ionization of Earth's upper atmosphere--and this led to a rare magnetic crochet. Alexander Avtanski observed the effect using a homemade magnetometer in San Jose, California. A magnetic crochet is a disturbance in Earth's magnetic field caused by electrical currents flowing in air 60 km to 100 km above our heads. Unlike geomagnetic disturbances that arrive with CMEs days after a flare, a magnetic crochet occurs while the flare is in progress. They tend to occur during fast impulsive flares like this one.

Solar Update Good morning. Beow is an updated image of the visible solar disk on Wednesday. Solar activity has been relatively low since the impulsive X3.3 flare event around sunspot 1890 yesterday evening. The active region continues to produce C-Class activity, including a C8.6 flare at 08:51 UTC. Sunspot 1890 is not quite as compact as yesterday as it continues to spread apart, but remains a complex cluster and has the potential to produce another major solar flare within the next 24-48 hours. A couple of new sunspots are forming in the southern hemisphere, and at least one of these regions should be numbered 1891 later today. All other visible regions remain fairly stable. Stay tuned to for the most up to date space weather news and information.

Updated 11/6/2013 @ 14:00 UTCM3.8 Solar Flare
Sunspot 1890 continues to produce moderate to strong flare activity on Wednesday. A fairly impulsive M3.8 event was detected at 13:46 UTC. The active region continues to rotate into a better geoeffective position for Earth directed explosions. Stay tuned for the latest updates.
UPDATE: A stream of plasma is seen jetting high above 1890 following the M3.8 solar flare. Click HERE for an image.
