Secular light curves of 25 members of the Themis family of asteroids, suspected of exhibiting low level cometary activity
I. Ferrin, M. Perez, J. Rendon
From 1996 to 2015 sixteen main belt asteroids were discovered exhibiting cometary activity (less than one per year), all of them during searches at the telescope. In this work we w…
Three Predictions: Comet 67P/Churyumov-Gerasimenko, Comet C/2012 K1 Panstarrs, and Comet C/2013 V5 Oukaimeden
Ignacio Ferrín
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 1…
"The 2009 Apparition of Methuselah Comet 107P/Wilson-Harrington: A Case of Comet Rejuvenation?"
I. Ferrín, Hiromi Hamanowa, Hiroko Hamanowa +5
(1) We find that comet 107P/WH was active in 1949, 1979, 1992, 2005, and 2009. (2) Its age can be measured. We find T-AGE=4700 comet years, WB-AGE=7800 cy. (3) This is a methuselah…
A Large Area CCD Camera for the Schmidt Telescope at the Venezuelan National Astronomical Observatory
C. Baltay, J. A. Snyder, P. Andrews +25
We have designed, constructed and put into operation a large area CCD camera that covers a large fraction of the image plane of the 1 meter Schmidt telescope at Llano del Hato in V…
