**** SPACE WEATHER OUTLOOK ****
Summary For July 28-August 3
Space weather during the week reached minor levels. Three category R1
(minor) radio blackouts occurred over the past week due to energetic
solar flares at 7:39 P.M. MDT on July 28th (29th at 0139 UTC), 10:10
P.M. MDT on July 29th (30th at 0410 UTC), and 5:54 P.M. MDT on August
2nd (2354 UTC). A category G1 (minor) geomagnetic storm lasted for
five day, from July 28th to August 1st. The source of this very long
geomagnetic storm was a large coronal hole on the sun and its
associated high speed solar winds. For a list of adverse system
effects related to space weather storms, please refer to the NOAA Space
Weather Scales.
Outlook For August 6-12
Space weather is expected to be at minor levels. The geomagnetic field
may reach category G1 levels on August 7th – 8th due to a coronal hole.
Category R1 radio blackouts are also possible during the week.
