**** SPACE WEATHER OUTLOOK ****

Summary For February 3-9

Space weather reached minor levels during the week. One category R1 (minor) radio blackout occurred on February 6th due to energetic solar flares on the sun. Geomagnetic storm periods reaching G1 (minor) also occurred on February 4th. For a list of adverse system effects related to space weather storms, please refer to the NOAA Space Weather Scales.

Outlook For February 12-18

Space weather may reach minor levels with possible R1 radio blackout conditions possible. There is also a chance for G1 geomagnetic storm periods on February 15th through February 17th due to a recurrent coronal hole, which produces high-speed solar wind. Geomagnetic storming is possible when the high-speed solar wind interacts with the Earth-s magnetic field.
