Asteroid Occultation Tracks for the UK and Ireland.
March - April 2013
Updated 2013 Feb 24
Maintained by Tim Haymes for the BAA Asteroids and Remote Planets Section - these are selected events only.
The IOTA high probability events (Global) are here
and all the low probability EAON events here.
Please check the links for detailed information before observing.

With thanks to EAON-ES: Pierre Vingerhoets, Emmanuel Thienpont and Oliver Klös for their regular alerts / updates.

[ Euraster.Net Results ] [ Observing techniques] [ Recording and Timing ] [ UK Summary and results ]


Selected events obtained from Occultwatcher software using updates from IOTA (World Wide) and EAON (index). Also look at Derek C. Breit's Current Global Asteroid Events

Map Legend: Blue lines are the predicted shadow edges. Its probable an occultation may be seen within the blue lines, but is not guaranteed ! The thick red lines mark the outer edges of the 1-sigma probability area where the track will be shifted by a lesser or greater degree, caused by errors in orbits, star positions and asteroid shape etc (About 65 % chance of a shift). An observer should be positioned within the thick red lines to monitor the star. With Occultwatcher you can see track updates.

Occulted star: Finder charts and full details of the event can be found by following the link to asteroidoccultation.com in the right hand column. After following this link, click on the black map to see the details e.g. the RA and Dec of the star, and UT markers on the track, finder chart.

Event UT: Its advisable to begin observing/recording about five minutes before the event and continue 5 min after. Please read the Observing techniques summary, and for a more detailed overview follow this link to: Recording and Timing Occultations

Key:
UT: Approximate time of occultation in the UK
Vis Mag: (VMag)Combined magnitude of the star and asteroid. For CCD observers the R magnitude is of interest. Follow the link for this information.
dMag: Magnitude drop during occultaion. For visual detection needs to be greater than 0.7.
Durn: Maximum duration of predicted occultation in seconds.

Criteria for selection:
If I think its an interesting one, i.e. larger asteroid, or bright star for visual observers. It's a mix of events suitable for CCD, Video and Visual observers.

Report result, Negative and Positive to Tim Haymes: tvh dot observatory at btinternet dot com and PLANOCCULT.
