Abbreviations, terms

Hp30 = maximum Hp30 index for the period; Kp = maximum Kp index for the period (indices for the variation of the earth’s magnetic field within 3 hours (Kp) or 30 minutes (Hp30))

Always in capital letters to emphasise the label character – NOAA Scales: QUIET (0 to 2) ▷ UNSETTLED (3) ▷ ACTIVE (4) ▷ G1 = G1 MINOR STORM (5) ▷ G2 = G2 MODERATE STORM (6) ▷ G3 = G3 STRONG STORM (7) ▷ G4 = G4 SEVERE STORM (8) ▷ G5 = G5 EXTREME STORM ( > 8.666)

Aurora = aurora, PL = aurora, HSS = high speed stream (fast solar wind), CH = coronal hole, CIR = corotating interaction region, ICME = interplanetary CME, CME = coronal mass ejection; DST = Disturbance Storm Time Index, NC = Newell Coupling, ☞ Videos = videos of eruptions in the solar corona, ☞ Re-analysis = CME identified in solar wind data

AKM-Forum = Classic web forum of the “Arbeitskreis Meteore” – among other things reference & documentation for aurora sightings in D, A, CH with scientific claim. Since 2004
