Moderately-strong G2-class geomagnetic storms are possible when the CME arrives. The long duration flare lasted more than 4 hours, so it put plenty of power into the CME. Big sunspot AR2936 was the source of the blast. It was hurled into space during the early hours of Jan. This movie from SOHO shows the CME leaving the sun yesterday: GEOMAGNETIC STORM WATCH: A coronal mass ejection (CME) is heading for Earth. The behemoth active region is big enough to swallow our planet 5 times over, and it is directly facing Earth, so any flares will be geoeffective. The likely source would be sunspot AR2936. Neutron counts from the University of Oulu's Sodankyla Geophysical Observatory show that cosmic rays reaching Earth are slowly declining-a result of the yin-yang relationship between the solar cycle and cosmic rays.ĬHANCE OF FLARES TODAY: NOAA forecasters say there is a 40% chance of M-class solar flares today, Jan. Credit: SDO/HMIĬosmic Rays Solar Cycle 25 is beginning, and this is reflected in the number of cosmic rays entering Earth's atmosphere. Big sunspot AR2936 poses a continued threat for M-class solar flares.
