Fabry's Comet and Barnard's Comet [PDF]

open access: yesNature, 1886
NOT having seen any mention of the rapid apparent growth of the tail of Fabry's comet, probably some of your readers are not aware to how great a length it extended. On April 26 occurred the first fine night after a very unusual series of overcast ones, and about 14h. G.M.T. I was surprised to see the tail reaching up to, or at least to within 1° of δ,

Three Predictions: Comet 67P/Churyumov-Gerasimenko, Comet C/2012 K1 Panstarrs, and Comet C/2013 V5 Oukaimeden [PDF]

open access: yes, 2014
We make the following predictions: (1) Comet 67P/Churyumov-Gerasimenko. The Secular Light Curve (SLC) of this comet exhibits a photometric anomaly in magnitude that is present in 1982, 1996, 2002 and 2009. Thus it must be real. We interpret this anomaly as a topographic feature on the surface of the nucleus that may be a field of debris, a region ...
