今天看到预报新消息，最大光度大概只有五等，m...

Hi all,
I analyzed the last visuals magnitudes received and my personal prediction
of maximun brightness for this comet based 145 visuals observations is m1
～5:
-350＜T＜-140 days m0＝3.1 , n＝10.9 , pre-conjunction,
- 80＜T＜- 30 days m0＝6.0 , n＝2.6 , post-conjunction
The comet has suffered a significant drop in activity conjunction post and
now only reflects almost like a solid body without gas or dust activity
n=2.6 ,this is typical of new comets from oort cloud in the heliocentric
range 1,7＜r＜1,4 u.a. , the most probable cause is volatil change dominate
the light visual curve of CO+→H2O.
