Observations of star occultations by asteroids

gb_flagSeite in DeutschFrameless version of this page

In the International Occultation Timing Association - IOTA many observers worldwide, profi astronomers and amateurs, are involved to observe star occultations by minor planets, or by planets with their moons or by the Earthmoon accurately and to collect the results via internet. Thus very often informations about a minor planet can be upgraded without the need of an expensive and time consuming mission with a spacecraft. A determination of the body shape of this minor planets as well as the discovery of satellites is possible from earth by a sufficient number of observations with good separated observer positions. Also the current orbital elements of an asteroid can be determined very accurate in this way. For data evaluation reports about a negative occultation are important in the same manner as the mostly smaller number of positve occultation reports.

About that on www.iota-es a page about the observation of star occultations by minor planets exists
Sternbedeckungen durch Kleinplaneten

Since August 2003 I am participating in this observation programs. Of course it is only possible on good weather conditions and if my time allows. Sadly many observations are disturbed in the important point of time by clouds or by dense fog. Then no report can be created and the necessary equipment with a mass of about 100 kilograms was just moved for astronomy science for some night hours in fresh air.

The reports of European observers which fulfill defined criterions are listed on www.euraster.net

The reports from North America are listed on
www.asteroidoccultation.com/observations/.

Read here about all my own observations and reports about star occultations by asteroids

From 08/2003 I was able to make 369 asteroidal occultation observations with 36 events recorded positive.
From this 369 reports 360 with a predicted duration of more than a second are listed on www.euraster.net.
