brightness of old comets

Bernd Brinkmann Mar 29, 2005

Hello Bill,

I just followed the discussion on the yahoogroups COMETS-ML about comet
C/1957 U1 (Latyshev-Wild-Burnham), which is 1957 IX in Guides database.

There seems to be no brigthness information for this comet within
Guides ephemeries, since it is listed with 99.0 mag. But at the end of
September 1957 it is drawn with a 45' wide coma and a 17 deg long tail.
It was discovered on Oct. 16 1957 with a pair of 7x50 binoculars, so
probably it was bright.

Are there some other information within Guide which are not displayed,
even in MORE INFO, which leads to this representation of a bright
comet(perhaps empirically, distance to the sun or earth, elongation)?

Clear skies
Bernd
