Hi All,
I observed the comet from my backyard in Caulfield .
Conditions were good.
LM 5.0
Comet 88P/ Howell
Oct 7.40UT, m1 8.6, Dia 6', DC= 4, 30cm Dobson (45X)
The comet is in Zodiacal light currently, and these estimates may be uncertain.

[ The comet shows a brighter inner coma after the recent minor outburst,
without a notable increase in the total visual magnitude till now ].

mistype can put confusion about the identity of one the previous observation
by COMAND. (Message 3747)
The measurement reported as P/Tritton (81P) should have been P/Tritton
(157P). As is it, to our knowledge, the first report of this comet, this
precision is important.

CometObs Group Policies
This group is for the posting of comet observations only.
Observations are formal estimates of a comet's magnitude,
apparent coma diameter, DC, or tail length.
In order to function as a clean repository of observations,
without the "noise" of intervening conversations, please direct
all discussion to our sister lists comets-ml or CometChasing.
Less formal comet observations are always welcome on the
CometChasing group.
