2019 Stellar Occultations by

TNOs, Centaurs, Irregular satellites and Trojans:

Campaigns

Here you find predictions to selected stellar occultations by TNOs/Centaurs, that are under campaign. We will do our best to update the prediction maps, so be alert for changes in this page (last update on 15/Mar/2019). If you can observe (or know who can) any of these occultations, please contact us(ribas-at-on.br or bruno.sicardy-at-obspm.fr).

Visit Bruno Sicardy's bibliogaphy web page too see some of our publications.
Visit http://occultations.ct.utfpr.edu.br for all the results on TNO and Centaur occultations obtained so far.

We just entered on a new era for the stellar occultations!
Our predictions make use of Gaia DR2 (Gaia Collaboration, 2018) for the position of the stars and the proper motions.With that the prediction errors are much smaller due to a accuracy of the star position and also to the re-reduction of the objects observations with the referred catalogue associated and new orbit calculation.
Information about the predictions can be found in ERC/Lucky Star project web page and in Assafin et al. 2010 (for Pluto system predictions), Assafin et al. 2012 (for the TNO predictions) and Camargo et al. 2014 (for TNO and Centaur predictions). Please, do references about the predictions to Assafin et al. 2010,  2012, Camargo et al 2014 and Desmars et al. 2015 papers, accordingly. Most predictions here are done with our own ephemeris, this is indicated on the top of the maps as NIMA ephem. NIMA-ephemeris is calculated by Josselin Desmars and provided by a numerical integration of the motion of the asteroid and by a fit to asteroid's observations Desmars et al. 2015. The observations come from Minor Planet Center and our own observations made at ESO, Pic du Midi, Calar Alto, Sierra Nevada and Observatorio do Pico dos Dias.


Informations about the maps (please read at least once!):
- The straight and continue lines are the shadow limits considering the estimated radius;
- Each red dot is spaced by one minute, the nominal occultation time is to the big dot (that is the geocentric closest approach);
- The arrow shows the direction of the shadow motion.
- The star G*, RP* and K* are the G, RP and K manitudes, normalized to a body moving at 20km/s.

- Be careful, the dates are from the moment of the event in Universal Time, the night of the event may begin at the date before.
