On Tuesday, June 11, between 1500 UTC and 2100 UTC, SWPC will perform a major network upgrade.



This upgrade will severely limit our operational capabilities. During portions of this period, SWPC will be unable to issue routine products, watches, warnings, and alerts. Access to products and data on the SWPC website will also be impacted, and sometimes, it will be severely limited or completely unavailable.


In the event of significant space weather activity, this maintenance will be postponed.
