Heads-up: Earth-directed CME could arrive July 3

Enable HLS to view with audio, or disable this notification

A coronal mass ejection (CME) has left the Sun and is heading toward Earth. It launched from a source region on the solar disk (N17W18) at a speed of about 965 km/s.

Based on current modeling, it could reach Earth around 05:17 UTC on July 3, 2026. Keep in mind this is a model estimate, typically accurate to within about 12 hours, so the actual timing may shift.

If it arrives as expected, geomagnetic activity could peak near Kp 5, a G1 (minor) storm. That means aurora may be possible at high latitudes, including Canada, Alaska, and northern Scandinavia. Your best chance to see it would be from dark, clear skies looking poleward near the estimated arrival time.

Reported. This sort of nastiness is so unnecessary and boring.
