We are looking for information to help get some idea of what to expect with
regard to the Perseid meteor storm predicted for August 1993. We presume that
the comet's return to perihelion in 1862 (what date was perihelion?) should
have caused storm levels also, particularly given its close approach of 32
million miles, but no one seems to have seen anything. In his 1988 book "Meteor
Showers", Gary Kronk, only refers to good rates (up to 215/hour, not really
storm rates) in 1861 and 1863 (no rates are given for 1862).

Was there a Full Moon on Aug. 9 1862 i.e. was moonlight the problem?

Did the comet and Earth's orbits not cross as closely as they do now?

Could it be that as the storm only lasts about 1 hour, an unpopulated part of
the dark side of the Earth was facing into the radiant (or poor weather)?

Does anyone have the precise times of maxima and Full Moons from 1860 to 1864?
It would then be interesting to see where in the world was favoured for seeing
the very best activity and if those places recorded anything unusual or not.
