(332706) Karlheidlas is an asteroid of the main belt that was discovered by Rainer Kresken and Matthias Busch on September 13, 2009 with the 1-meter telescope of the Optical Ground Station (OGS) of the Teide Observatory at the European Northern Observatory on Tenerife .
The asteroid orbits the Sun at about 20 km / s at a distance of 1.8 to 2.6 astronomical units in about 3.3 years . Its orbit is inclined 4.8 ° to the ecliptic , the orbital eccentricity is 0.16. Based on the absolute brightness of the asteroid and assuming that it is a typical main belt asteroid, its mean diameter is approximately one kilometer.
The first unconfirmed sighting took place in 1996 as part of the NEAT program with the Ground-based Electro-Optical Deep Space Surveillance (GEODSS) telescope on the Haleakalā volcano on Maui . It was not until eight years later that the asteroid could be observed again on Maui at the AMOS . By 2007, four more unconfirmed sightings followed, both in Arizona at the Steward Observatory ( Kitt-Peak Spacewatch and Mount Lemmon Survey ) and in New Mexico at the Lincoln Laboratory ETS .
Since 2009, Rainer Kresken and Matthias Busch, both members of the Starkenburg observatory in Heppenheim , have been using the idle times of the OGS 1-meter telescope, which is actually intended for observing space debris and for tests on laser communication with satellites in order to search the sky for asteroids . They discovered (332706) Karlheidlas during the first observation phase in September 2009. In the meantime, a team of more than 40 volunteers under the name TOTAS (Teide Observatory Tenerife Asteroid Survey) is evaluating the recordings of the individual observation nights .
On January 16, 2014, the IAU officially named the asteroid after the German chemist and amateur astronomer Karl Heidlas (* 1932), who headed the Volkssternwarte Aachen for more than 20 years and made a special contribution to its reconstruction and maintenance.
