- Description:
- About 200 observations from AD66 to 1910 of the tail length of Comet Halley have been used to derive the mean tail length of the comet as visible to the naked eye under very good observing conditions, The curve, covering an interval of -45-^ (t-T)^ 80 days, is skewed and peaks at -SS million km for (t-T) secular decrease of the tail length.
