Date/Time Issued: June 10, 2026 2105 UTC

Product(s) or Data Impacted: All SOLAR-1 Products

Date/Time of Initial Impact: June 10, 2026 0000 UTC

Date/Time of expected end Time: N/A 

Duration: NA

Details/Specifics of Change:

The SOLAR-1 observatory from NOAA has officially commenced operations, signifying a pivotal advancement in national preparedness for space weather. As the first American satellite dedicated solely to ongoing, operational solar monitoring, SOLAR-1 represents a new standard in space weather observation. SOLAR-1 maintains the critical observations required to safeguard terrestrial infrastructure and support future crewed space exploration by improving storm readiness.The spacecraft, formerly designated as SWFO-L1, began its mission on September 24, 2025, launching from Kennedy Space Center via a SpaceX Falcon 9. Following a four-month journey covering approximately one million miles, it reached the Sun-Earth Lagrange point 1 (L1). From this orbital position, it provides constant surveillance of solar wind and coronal mass ejections. Achievement of operational status followed an intensive eight-month commissioning phase. During this period, collaborative teams from NOAA and NASA verified all essential systems—including propulsion, communications, and power—alongside every onboard scientific instrument.
