preliminar light visual curve of comet C/2016 U1 NEOWISE

My analysis of the visual light curve of Comet C / 2016 U1 NEOWISE indicates that the comet based on its abosolute magnitude of m0 = 11.0 would have an estimated core diameter of D = 1.15 kms (Navarro 2016) based on the formula Of Sosa & Fdez, 2011, and a core radius of Rn = 0.575 km, and an estimated mass of M = 0.3x10 ^ 12 kg (Navarro 2016), my initial conclusions show that this is a small fragment of new comet Of the Oort cloud with very volatile "ice volatiles", the images show a very gaseous and little dusty comet, where the sublimation of gas is greater than the dust, probably a fragment of giant comet detached.
