Afp data obtained by the application of the  CARA approuch

Af(rho) data available via request to CARA-coordinator

http://cara.uai.it

Comet C/2012 S (ISON) looks in outburst, the coma is more bright and magnitude is about 1 magnitude brighter, Af(rho) value with R-Bessel filter (CARA-apprauch) is more than double in comparison with data of 9 nov. (Afrho from 300cm to 702 cm).

With R-Bessel filter
