The Five W's of GOES-19 and CCOR-1

Who

NOAA, which operates the GOES series of weather satellites and its Space Weather Prediction Center uses CCOR-1 imagery.

What

A weather satellite whose CCOR-1 coronagraph watches the corona from 3.7 to 17 solar radii, replacing the aging coronagraphs on SOHO.

When

Launched June 25, 2024; CCOR-1 first light September 19, 2024; operational as GOES-East April 7, 2025.

Where

Geostationary orbit at 75.2° West, making CCOR-1 the first coronagraph to fly in geostationary orbit.

Why

Coronal mass ejections can disrupt satellites, GPS and power grids; seeing them early gives forecasters time to warn operators.

Impact Statement

Agency solution · active

NOAA's GOES-19 became the operational GOES-East satellite on April 7, 2025. On board is CCOR-1, the world's first operational, space-based coronagraph dedicated to space weather: it blocks the Sun's bright disk and images its faint outer corona every 15 minutes to spot coronal mass ejections heading our way.
