**** SPACE WEATHER OUTLOOK ****

Summary For April 7-13
Space weather has reached moderate levels during the week. A category
R1 (minor) radio blackout occurred on April 4th at 1:19 PM MST (2019
UTC) due to an energetic solar flare on the sun. High speed solar wind
from a coronal hole on the sun was the cause of a category G2
(moderate) geomagnetic storm on March 31st and a category G1 (minor) on
April 1st. A second category G1 storm occurred on April 4th and 5th.
For a list of adverse system effects related to space weather storms,
please refer to the NOAA Space Weather Scales.

Outlook For April 16-22

A category G1 (minor) geomagnetic storm is possible late in the week due
to another large coronal hole with high speed solar winds. There is a
slight chance of a category R1 (minor) radio blackout during the week
due to a couple of moderate sized sunspot regions with the potential
for moderate flares.
