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
