Geomagnetic Environment
Today’s window: avg 1.81, peak 2.3 — Quiet.
Minor fluctuations in Earth’s field. Compass needles may show slight deviation at polar latitudes. No significant impacts on infrastructure.
Kp 0–1 (quiet — no effects) • Kp 2–3 (unsettled — weak polar aurora) • Kp 4 (active — aurora at 65°+ latitude) • Kp 5 (minor storm — aurora to 60°) • Kp 6 (moderate storm — aurora to 55°) • Kp 7 (strong storm — aurora to 50°) • Kp 8 (severe storm — aurora to 45°, grid stress) • Kp 9 (extreme storm — aurora to 40°+, outages possible)
Solar Phase
Day length today: 12.18 hours (Spring, ↑ lengthening). 86 days to the next solstice. The solar cycle sets the biological clock of every organism on the planet — a free, universal timing signal available to anyone paying attention. Days are lengthening rapidly. Energy and mood typically climb with day length — this is the window for ambitious projects. Prioritize deep work in the morning hours. Day 86 of 365.
