The 2009 apparition of comet 107P was observed with a variety of instruments from six observatories. The main results of this investigation are: (1) 107P/Wilson-Harrington was found to be active not only in 1949 but also in 1979, 1992, 2005 and 2009. The activity is very weak and produces only a slight brightness increase above the nucleus. (A(SEC)=V-NUC(1,1,0)-m(1,1) 100 comet years), medium size (1A < D-EFFE = 3.67 < 6 km) nucleus, fast rotating (P-ROT = 6.093 h < 7 h). belonging to the… Expand
Erratum: Secular Light Curves of NEAs 2201 Oljato, 3200 Phaethon, 99942 Apophis, 162173 Ryugu, 495848 and 6063 Jason
Using the Secular Light Curve (SLC) formalism (Ferrin, 2010a, PSS, 58, 365-391), we searched for cometary activity of six NEAS: 2201 Oljato. The SLC exhibits significant cometary activity andExpand
The Pinpoint Comets: 133P/Elst-Pizarro, 249P/LINEAR, 331P/Gibbs, 62412 and 6478 Gault
From two Active Asteroid (AA) known in 1979 we have advanced to 37 members at the beginning of 2019. More surprisingly, in the first three months of 2019 five new members were added to the list, oneExpand
“Secular light curves of 25 members of the themis family of asteroids, suspected of low level cometary activity”
Abstract From 1996–2015 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 will exploreExpand
The impending demise of comet C/2012 S1 (ISON)
Abstract We present evidence to conclude that it is very probable that comet C/2012 S1 (ISON) will disintegrate before reaching perihelion. Fig. 1 , Fig. 7 of this work are particularly revealing.Expand
SAFARI: Searching Asteroids for Activity Revealing Indicators
Active asteroids behave dynamically like asteroids but display comet-like comae. These objects are poorly understood, with only about 30 identified to date. We have conducted one of the deepestExpand


We present the optical observations of the Near Earth Object 107P/(4015) Wilson–Harrington during the 2009/ 2010 apparition taken in search of low-level comet activity. Our photometric andExpand
"Secular Light Curves of Comets, II: 133P/Elst-Pizarro, an Asteroidal Belt Comet"
Abstract We present the secular light curve (SLC) of 133P/Elst–Pizarro, and show ample and sufficient evidence to conclude that it is evolving into a dormant phase. The SLC provides a great deal ofExpand
Secular light curve of Comet 28P/Neujmin 1 and of spacecraft target Comets 1P/Halley, 9P/Tempel 1, 19P/Borrelly, 21P/Giacobinni-Zinner, 26P/Grigg-Skjellerup, 67P/Churyumov-Gerasimenko, and 81P/Wild 2
Abstract We present the secular light curves of eight comets listed in the title. Two plots per comet are needed to study these objects: a reduced magnitude (to Δ = 1 AU = geocentric distance) vsExpand
Secular light curve of 2P/Encke, a comet active at aphelion
Abstract We present the secular light curve of Comet 2P/Encke in two phase spaces, the log plot, and the time plot. The main conclusions of this work are: (a) The comet shows activity at perihelionExpand
Secular light curve of Comet 9P/Tempel 1
Abstract In support of the Deep Impact Mission, we have updated the secular light curve of 9P/Tempel 1 presented in Paper I [Ferrin, I., 2005. Icarus 178, 493–516], with new data sets. The secularExpand
Secular light curve of comet 103P/Hartley 2, target of the EPOXI mission
In support of the EPOXI mission, we have compiled and updated the secular light curve (SLC) of comet 103P/Hartley 2, a Jupiter Family comet, the next target of the Deep Impact extended mission. WeExpand
Photometric observations of 107P/Wilson–Harrington
Abstract We present lightcurve observations and multiband photometry for 107P/Wilson–Harrington using five small- and medium-sized telescopes. The lightcurve has shown a periodicity of 0.2979 dayExpand
Analysis of POSS Images of Comet-Asteroid Transition Object 107P/1949 W1 (Wilson-Harrington)
Abstract We have analyzed the only two known images taken of Comet 107P = Asteroid (4015) Wilson–Harrington while it was a distinctly cometary object. The images reside on two Palomar Observatory SkyExpand
The nuclei of comets 126P/IRAS and 103P/Hartley 2
We report the detection of the nucleus of 126P/IRAS and 103P/Hartley 2 with the Infrared Camera of the Infrared Space Observatory (ISOCAM). 126P/IRAS was observed on 12 November 1996, when it was atExpand
