Lunar Occultations of Close Double and Kepler2 Stars in December 2014 for Australia and NZ


The list shows possible double stars, with separations less than 2", predicted to be occulted by the Moon during December 2014 and visible from parts of Australia or New Zealand. The listing is a very abbreviated version of predictions produced by Occult plus an indication of the region of visibility. Observers need to generate their own precise predictions using Occult.

Observations of all pairs in the list are highly desirable. Those showing an OCc number have been reported as non-instantaneous at a lunar occultation. Confirmation or otherwise of any double nature is wanted.

*** Kepler stars are also included in the list. Light curves for the occultation of these stars are also required. Reporting of these events is still being sorted out, with a system in Occult coming soon. In the meantime please archive any observations of Kepler stars, see 14 December below, keeping both the video and the light curve.

The list below is generated by OCCULT for a 25cm telescope. Some of the events may be beyond the reach of smaller telescopes.

Please send reports of all observations of these stars to Brian Loader at palbrl@clear.net.nz, including any made in earlier months and not so far reported. And of course if you observe a stepped event for a star, which is not a known double, please report this. More details about reporting follow the predictions.

Reporting Your Observations

The most convenient way of reporting is to use Dave Herald's new version of OCCULT which has a Double Star report option in the Observations editor. Before using it, generate a light curve with Limovie and copy to the clip board. Your graph will be attached to the email which you can then send to palbrl@clear.net.nz.

Otherwise in reporting please include your name and positional data as for other occultations reports, also your telescope type and method of observing and timekeeping.

For each event give the star name and the times of each step of the event with the corresponding accuracy. The limb PA, Rv and Cct of the event would also be useful.

In addition to measures of the PA and separation of binary stars, there is also a need for an estimate of the magnitude difference. An estimate of this can be made from the step sizes shown by Limovie data. So if possible a determination should be made of the size of each step together with an estimate of accuracy.

Please also report cases where a double event is predicted but none detected. These are especially likely with stars shown with an OCc designation
