Table of Long Quiescent Filaments ( > 20 Degrees Heliographic) and Relative Skew of Corresponding Arcades in Overlying Corona Last changed 2/12/96. 68 filaments over 20 degrees ----------------------------- 3 indeterminate filaments (all diffuse arcades) 2 ambigous filaments 6 weak filament determinations (one of these was an ambiguous possible exception) 57 clear filaments (8 ambiguous or weak filaments) ------------------- 12(1) ambiguous arcades (2 possible exceptions, both polar crown) 4(7) unclear arcades, diffuse or faint (1 possible exception) 45 arcades with at least probable identification ------------------------------------------------ 11 probable identifications (including the 2 ambiguous filaments) 34 clear arcade identifications (all clear filaments) =============================== Of the 34 confirmed cases: 15 Dextral 13 in the north 2 in the south 19 Sinistral 17 in the south 2 in the north [Before we had 16/17 with 3 exceptions each] Note: there were one or two events which Sara had marked as confirmed that my notes don't show a clear determination for..
