Earth's heartbeat on
Friday, September 11, 2026
Earth's electromagnetic pulse is showing elevated activity, particularly with a persistent, unusual peak around 12 Hz and a recent surge in the fundamental frequency band. This indicates a period of increased energetic flow within the Earth-ionosphere cavity.
Conditions are expected to remain stable over the next 24-72 hours, with no significant geomagnetic activity anticipated. The solar wind is normal and the magnetosphere is well-shielded by a northward IMF.
A mostly settled night. One or two mild factors are pushing the index down, but nothing dramatic. Most sleepers will not notice anything; sensitive individuals may take slightly longer to drift off.
Estimate based on real measurements that night. Sleep effect grounded in peer-reviewed studies (Cajochen et al., Current Biology 2013 on lunar phase; Babayev 2002 on geomagnetic-melatonin coupling). Not medical advice.

Correlation is not causation. This is for self-reflection, not medical advice. If you have persistent concerns, talk to a doctor.
This is a good time to practice mindfulness and stay aware of your energy levels, perhaps incorporating gentle movement or stretching.
