Actual Astronomy - Observer’s Calendar For September

Hosted by Chris Beckett & Shane Ludtke, two amateur
astronomers in Saskatchewan. actualastronomy@gmail.com


- Sept 1 - Aurigids ZHR=10 related to Comet Keiss


The comet was discovered by Carl Clarence Kiess at Lick
Observatory on a photographic plate obtained in the morning hours
of 6 July 1911 with the Crocker photographic telescope. The comet
appeared as a distorted nebulous object with a short tail. The
presence of the comet was confirmed visually the next day. The
comet had a well condensed nucleus and a faint tail. In
photographs the tail was four degrees long. The comet then was of
seventh magnitude and moving southwards. A preliminary orbit
suggested the comet was past its perihelion upon discovery and it
was calculated that it would approach Earth at a distance of 0.27
AU (40 million km; 25 million mi) on 20 August. On 19 August the
comet was reported to be visible with the naked eye, peaking at
an estimated apparent magnitude of 5.


The comet had been suggested in 1911 to be the return of comet
C/1790 A1 (Herschel), also known by its old designation, 1790
I.However, further calculations revealed that the orbit of comet
Kiess had an eccentricity too high for an orbital period of 122
years, with the orbit calculated by Louis Lindsey in 1932
indicating an orbital period of 1,903 years.
