Overview
- The first solar shockfront reached Earth after local dawn and triggered only a weak geomagnetic response, so nothing visible was missed overnight.
- Experts say the likelihood of sightings is slightly elevated rather than high, with Hamburg Planetarium’s Björn Voss and Haus der Astronomie’s Carolin Liefke urging tempered expectations.
- Weather will decide most viewing chances, with the DWD pointing to western Schleswig-Holstein and central Lower Saxony for clearer skies early at night before fog spreads.
- In Baden-Württemberg, patchy mid-level clouds may leave brief gaps, with higher terrain such as the Black Forest and Swabian Alb offering better odds for clear spells.
- NOAA expects geomagnetic activity to increase from March 21 due to a coronal hole, with a forecast of at least G2 conditions and a small chance of G3, so real-time alerts and monitoring are advised.
