The Search for Occultation Screen

• Use Search to conduct searches using 1 or more asteroids, various filter options, for 1 month through an entire year.

• Pull down menus facilitate the setup of filters for many of the occultation events noted in major publications.

• Extensive overnight searches can be defined to examine thousands of asteroids.

• Successful searches can be studied immediately using the View Occultation Screen, described next, or accumulated in a Browse Set for examination later when more convenient using the Browse Occultation Screen.

• This example shows a search in the month of May 1995 using one asteroid, 74 Galatea, and a user auxiliary star database, UOB.

• Filters select asteroid magnitude range, angular size, magnitude drop of the occultation, a combination of asteroid angular size and stellar magnitude used by the IOTA organization and shadow duration.

• Close calls or appulses between the asteroid and stars are noted during the search.

• The appulse distance can be set by the user. Status bars and values record the progress of the search process.
