Geomagnetic Storm Watch Issued After Solar Flare; Auroras Possible Over Northern India

Following an M1.9-class solar flare from sunspot region AR4461 on June 6, 2026, a fast-moving coronal mass ejection (CME) was projected to reach Earth between June 7 and June 8. In response, the NOAA Space Weather Prediction Center issued watches for G2 (moderate) to G3 (strong) geomagnetic storming.

Potential Impacts

Geomagnetic storms of G2–G3 intensity can impact satellite communications, GPS navigation accuracy, and power grid operations. Airlines operating polar routes may need to reroute flights to avoid elevated radiation exposure. However, for skywatchers, these storms also present opportunities to view auroras (Northern Lights) at latitudes much farther south than usual, with reports suggesting possible visibility in parts of northern India and the northern United States.

Scientific Context

The Sun is currently near the peak of Solar Cycle 25, which has been more active than initially predicted. Increased solar activity leads to more frequent CME events and geomagnetic disturbances. Simultaneously, Venus and Jupiter were prominently visible in the night sky during this period, with the two planets appearing side-by-side on June 7 and approaching a close alignment.
