- 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.
