Depends. If you're outside at night and tilt your head up, the Default Mode Network of your brain may be temporarily suppressed, while dopamine may increase.

TL;DR: A severe (G4-level) geomagnetic storm hit Earth on January 19, 2026 due to a solar coronal mass ejection. It can disrupt power grids, GPS, satellite systems, and radio communications, while creating visible aurora displays at higher latitudes.
