Optical observations of 23 distant Jupiter Family Comets, including 36P/Whipple at multiple phase angles
Colin Snodgrass, Stephen C. Lowry, Alan Fitzsimmons
We present photometry on 23 Jupiter Family Comets (JFCs) observed at large heliocentric distance, primarily using the 2.5m Isaac Newton Telescope (INT). Snap-shot images were taken…
Photometric observations of Rosetta target asteroid 2867 Steins
Paul R. Weissman, Stephen C. Lowry, Young-Jun Choi
Asteroid 2867 Steins is one of two flyby targets of ESAs international Rosetta mission, launched in March, 2004. We obtained photometric observations of Steins on April 14-16, 2004…
Rotation and Color Properties of the Nucleus of Comet 2P/Encke
S. C. Lowry, P. R. Weissman
We present results from CCD observations of comet 2P/Encke acquired at Steward Observatory's 2.3m Bok Telescope on Kitt Peak obtained in Oct. 2002, when the comet was near aphelion…
Determination of the light curve of the Rosetta target Asteroid (2867) Steins by the OSIRIS cameras onboard Rosetta
M. Kueppers, S. Mottola, S. C. Lowry +9
Context: In 2004 asteroid (2867) Steins has been selected as a flyby target for the Rosetta mission. Determination of its spin period and the orientation of its rotation axis are e…
Photometry of cometary nuclei: Rotation rates, colours and a comparison with Kuiper Belt Objects
Colin Snodgrass, Stephen C. Lowry, Alan Fitzsimmons
We present time-series data on Jupiter Family Comets (JFCs) 17P/Holmes, 47P/Ashbrook-Jackson and 137P/Shoemaker-Levy 2. In addition we also present results from `snap-shot' observa…
The nuclei of comets 7P/Pons-Winnecke, 14P/Wolf and 92P/Sanguin
C. Snodgrass, A. Fitzsimmons, S. C. Lowry
Jupiter Family comets (JFCs) are short period comets which have recently entered the inner solar system, having previously orbited in the Kuiper Belt since the formation of the pla…
