Spots, Kp, Bz and Dst
Bz is the most southward value in each interval. A dot on Kp means Kp reached 5; a dot on Dst means Dst reached −50 nT.
X-ray, protons and flares
X-ray is the 0.1–0.8 nm flux. Markers are C-class and stronger: those flares fade HF on the daylit side. Protons are the ≥10 MeV flux, which causes polar-cap absorption once it passes 10 pfu.
