IB flare relocation 1B = a bright flare of importance 1 in H-alpha classification Explanation: The brightness levels are generally divided as faint (F), normal (N), or bright (B). For example, a bright flare of importance 1 in H α will be denoted as Class 1B flare. ----------------- H-alpha classification An earlier flare classification was based on Hα spectral observations. The scheme uses both the intensity and emitting surface. The classification in intensity is qualitative, referring to the flares as: faint (f), normal (n) or brilliant (b). The emitting surface is measured in terms of millionths of the hemisphere and is described below. (The total hemisphere area AH = 15.5 × 1012 km2.) Classification Corrected area (millionths of hemisphere) S < 100 1 100–250 2 250–600 3 600–1200 4 > 1200 A flare then is classified taking S or a number that represents its size and a letter that represents its peak intensity, v.g.: Sn is a normal sunflare. ¡Espero que te sea útil! |
