Satellite sector moved
Satellite moves MDS STATUS...
Each GOES weather satellite has two “mesoscale sectors” — small, movable windows that the satellite photographs roughly every 60 seconds, far more often than its routine full-disk and continental scans. Forecasters aim them at whatever is most important that day. This section announces where they are being pointed and for how long.
GOES-West is pointing mesoscale sector 1 over Alaska, about 375 mi SSW of Juneau, AK — in support of wx ops at WFOs Juneau and Anchorage. That means this patch of sky gets a fresh satellite image about once a minute instead of every 5 to 10 minutes, so forecasters can watch storms develop almost in real time.
