The tables below list the asteroidal occultations that will be visible over North America, Central America and the Caribbean during the next month. The maps for each event will show the path of the asteroid above the earth.

If you need general information about occultations and how to observe them please visit the International Occultation Timing Association's web site at http://www.lunar-occultations.com/iota/iotandx.htm.

The maps to which the listings link were created using the Google Maps API which is recently out of beta testing and may not compatible with all browsers. New users of this site should read the Compatability Issues page to learn of any issues with these maps and their browser. In particular, read about positional accuracy of the lines in the yellow box on that page.

Most maps open in a new browser and display The US including (AK and HI), Canada, Mexico, Central America and the Caribbean. Clicking once on the map's button will show the track on a map of the entire world.



Asteroidal Occultations Visible from North America

Listed below are asteroidal occultations that will be visible from somewhere in the North America, Central America and the Caribbean (weather permitting).

Events highlighted in yellow may be of interest to New York City observers.

For information on table headings see the Table Legend below.

Table Legend

Date The date and time in Universal Time (UT) when the asteroid will be at the midpoint of its track above earth while occulting the target star. This location may not be anywhere near you so you can not necessarily use this time for when to begin your observations.
Asteroid The number and name of the asteroid.
Star The catalog number of the target star. Common catalogs are:
  • HIP - Hiparcos catalog compiled by the European Space Agency based on optical observations by the Hipparcos Satellite. The standard reference catalog for optical astrometry.
  • TYC - Tycho-2 Catalog is reanalyzed data from the Hiparcos and provides better positional accuracy than the Tycho-1 catalog and a larger database. Work performed by USNO and the Copenhagen University Observatory.
  • UCAC2 - US Naval Observatory CDC Astrograph Catalog, data release 2 based on photometric data. The final catalog is expected in 2006.
  • 2UCAC - UCAC2 stars that need more research before a difinitive magnitude can be assigned. Listed magnitude may be off by +/- 0.5m.
Magnitude My Get-Out-Of-Bed criteria #1 — Is the target star bright enough for me to see it with my optics?
Drop My Get-Out-Of-Bed criteria #2 — Will the star's magnitude dim enough that I will be able to observe it happen? This may not be a concern for you if you record occultations digitally and can use a computer to detect small changes in brightness.
Duration My Get-Out-Of-Bed criteria #3 — Will the dimming last long enough for my mind to register what my eyes saw? This may not be a factor for you if you record occultations digitally and can play the recording in slow motion.
Track A listing of the regions over which the asteroid will pass. For purposes of describing the tracks I have adopted the following conventions:
  • Alaska and Hawaii are listed separately from the rest of the USA.
  • USA means the Lower 48 states.
  • The Bahamas are included in The Caribbean.
  • The track is described from left to right, the way I read, and not in the order in which the asteroid passes over the track.
Also note that these track maps depict the track of the asteroid over the earth and not necessarily where it can be seen. The track listings upon which these tracks are based include portions or the tracks which may be in sunlight and therefore not visible. I don't know of an easy way to determine which data points they are and excerpt them from the tracks. And occultations may be visible farther from the path centerline than the 1 σ Path Error Limit Line depicted on the maps.
Created The date on which the map was created or last updated. It may not be the last time the map page was updated. It should be within a couple days of the date the data upon which it was based was updated as listed beneath the map.
