Summary For July 12-18

Space weather reached strong levels this period. Minor (R1), moderate
(R2), and strong (R3) radio blackouts were observed every day of the
summary period due to solar flare activity from active sunspot Regions
646 and 649. Category G1 (minor) and G2 (moderate) geomagnetic
storming occurred on 17 July due to a cloud of magnetic material from a
solar flare on the Sun that impacted Earth.

Outlook For July 21-27

Space weather for the next week is expected to reach moderate levels
with a chance for strong levels. Two complex sunspot clusters
currently are visible on the Sun and both have potential to produce R1
(minor) and R2 (moderate) radio blackouts. There is a chance also for
an isolated R3 (strong) blackout from these sunspot groups. Minor to
moderate geomagnetic storms and radiation storms are also possible.
