  Comet 231P/LINEAR-NEAT observed around aphelion at 4.88 AU, using 2.0 m
Himalayan Chandra Telescope at Mt. Saraswati, Hanle , India. CCD aperture
photometry performed and $R_{C}$-band magnitude $21.37\pm 0.08 $ mag obtained.
Comet 231P surface brightness profiles compared with field star and found
similar, within low level noise in the data; its implicate no cometary
activity. We measured dust production levels in term of the quantity $Af\rho$,
which was estimated 5.0 cm. Most of the comet observed at perihelion but not
aphelion, if we need to calculate total comet dust contribution in the solar
system, this type of study may play important role.
