Minor Planet (49109) Agnesraab

In January, 2004, the Minor Planet Circulars (MPCs) announced the naming of minor planet (49109) as follows:

(49109) Agnesraab = 1998 SO2
Discovered 1998 Sept. 18 by R. Linderholm at Lime Creek.
Austrian amateur astronomer Agnes Raab (b. 1969) is a long-time member of the Linzer Astronomische Gemeinschaft. The first prediscovery image of this minor planet was found on a plate exposed on her eighth birthday.

The image shown above is an animation made of the disvovery images, showing the motion of the asteroid during the 25 minutes between the two exposures. The minor planet was discovered by Bob Linderholm on these images, taken with a SBIG ST-7 CCD camera on a 10" Meade LX200 Schmidt-Cassegrain telescope at the Lime Creek observatory in Nebraska, USA. The telescope was operating at a focal length of 900mm, and the images cover about 26.3' x 17.6'. (The apparent size of the moon, for comparison, is about 30'.) An image of the discoverer and his equipment can be seen below.

After Linderholm's discovery, the minor planet was als found on a photographic plate exposed with the UK Schmidt-Telescope at Siding Spring Observatory in Australia on July 21, 1977 - the eight birthday of Agnes! Part of that image, with the trail of the minor planet at center, is shown below. (Image extracted from the Digitized Sky Survey - Copyright and Acknowledgements)
