Space Weather Alerts

GET /spaceweather/alerts

Get current space weather alerts and warnings from NOAA's Space Weather Prediction Center (SWPC). Returns active geomagnetic storm watches, solar radiation storms, radio blackout alerts, and other space weather advisories. Each alert includes severity level, issue time, and description. Essential for aurora chasers, satellite operators, aviation planners, and power grid managers who need to monitor geomagnetic disturbances.
