103P/Hartley early results

The preliminary results from the 103P/Hartley campaign shows that this year the comet is displaying a different behavior than in 2010/11, with a much lower general dust production at perihelion.

Afrho refers to a 5000 km window at the comet and it is corrected to a zero phase angle.

Comet 103P/Hartley 2023 observing campaign

Comet 103P/Hartlety was intensively observed in 2010/2011 to support the direct exploration of its nucleu by the EPOXI NASA spacecraft. The comet is returning this year with favourable observing conditions and it is an unique opportunity to improve our knowledge on this peculiar object.

A special observing CARA campaign is being launched to follow 103P in the coming months.  According to our protocols R band images are mandatory for photometry, as well as for image processing and analysis.

Further details on the CARA campaign will be communicated soon as things go on.
