  We present our results for comet (ISON). Our results were obtained with
amateur telescopes observing from the ground, before and after the comet had
passed conjunction with the Sun in August 2013. We measured a mean radius of
830 +- 245 m, and we have identified a persistent structure in the direction of
the sun with a preliminary rotation period of approximately 3 days. In the tail
are visible peculiar structures linked to the production of dust by the
nucleus. Our data Af(rho) (AHearn et al. 1984), a physical parameter that
indicates the amount of dust produced, is approximately 500+-50 cm in the quite
phase which means a production Qdust=500kgxsec^-1 equal to 43.2x10^6 kg per
day. A considerable amount for a small comet. We have also detected two major
outbursts in January, 2013 and November, 2013, and minor outbursts throughout
the observation period. Key words: General: general; comets: C2012 S1 (ISON),
ISON, comets, afrho, photometry of aperture, flux, apparent magnitude, absolute
magnitude, fragmentation.
