SOLAR-1 Is Now The New Designation for SWFO-L1

SOLAR-1 is new name for SWFO-L1
SOLAR-1 Is Now The New Designation for SWFO-L1
published: Tuesday, January 27, 2026 16:32 UTC

On January 23, 2026, NOAA’s Space Weather Follow On – Lagrange 1 (SWFO-L1) observatory executed its final engine burn, successfully entering its final orbital position at Lagrange point 1. Located roughly one million miles from Earth, this unique vantage point allows the satellite to continuously monitor the sun and space weather before it reaches our planet. The observatory has now been officially renamed to Space weather Observations at L1 to Advance Readiness – 1 (SOLAR-1). The satellite is expected to be operational during the upcoming spring of 2026. The full story can be found here.
