What is this?
A place that sets objective space-weather data beside your own body's notes. No presupposed answers, no fear-selling, no causal claims.
- Check tonight — Kp, Dst, flare class, 3-day forecast, straight from NOAA / Kyoto WDC raw feeds.
- Log tonight — 30-second entries: sleep, head, mood, energy. Auto-paired with that day's Kp.
- Read the mirror — after 30 days, your personal overlap chart. If the sample is too small to conclude, it says so.

What does the science say?
Common questions
Can a geomagnetic storm give me a headache or insomnia?
Population-level studies find statistical associations between strong storms and cardiovascular events and blood-pressure shifts (grade A/B evidence). But no study can predict or explain one individual's symptoms. Your experience is real and worth recording — that's exactly why this tool exists.
How is this different from astrology?
Every health claim carries a DOI-checkable evidence grade (A/B/C); missing data stays marked; nothing is interpolated; no Mercury-retrograde predictions. The cosmos is mysterious; the method is honest.
