Calculations of physical parameters of comet C/2023 P1 NISHIMURA

The new estimated nuclear radius of the comet is RN = 0.75 +/- 0.02 kms.

The active area fraction of the core surface is (F)+/-o= 1.4+/- 0.0

Its estimated mass is log10 M(n) = 11.6

Its maximum water production rate is Log Q (H2O) > 3,000 kgrs /sec or 10^29.50 mol s

Power law R(-3.4)

Absolute Magnitude Nuclear R BandRN ( 1,1,0 )=+18.23
