Forecasters at NOAA's Space Weather Prediction Center said the sun's coronal mass ejection (CME) that reached Earth on Jan. 9, unsettled the geomagnetic field but did not cause storm conditions to be reached due to the weak magnetic field.
While there is still a chance we could see some geomagnetic storming that threat is greatly diminished.
The sunspot in Region 1944 that produced the eruption at 1:32 p.m. EST Tuesday, Jan. 7 has had no significant additional flaring and shows signs of decay.
To monitor events on the sun, SWPC staff utilize a variety of ground- and space-based sensors and imaging systems to view activity at various depths in the solar atmosphere. A worldwide network of USAF-sponsored optical observatories also provides space weather forecasters with detailed, plain-language information about activity in and around sunspot groups, as well as other areas of interest on the sun.
Space weather forecasters also analyze the 27-day recurrent pattern of solar activity. Based on a thorough analysis of current conditions, comparing these conditions to past situations, and using numerical models similar to weather models, forecasters are able to predict space weather on times scales of hours to weeks.
