**** SPACE WEATHER OUTLOOK ****

Summary For January 13-19

There has been no significant space weather during the past week. While
a number of sunspot regions have appeared on the visible sun during the
past week none of them produce any significant solar flares. They have
been quiet and relatively stable. For a list of adverse system effects
related to space weather storms, please refer to the NOAA Space Weather
Scales.

Outlook For January 22-28

Space weather may reach minor levels during the next week. An active
sunspot region is due to rotate onto the visible sun in the next day or
so with the potential to produce R1 (minor) radio blackouts. A
category G1 (minor) geomagnetic storm is possible on January 23 – 24th
due to recurrent coronal holes which produce high-speed solar wind.
Geomagnetic storming is possible when the high-speed solar wind
interacts with the Earth-s magnetic field.
