named asteroid (410928) Maidbronn (discovery image, object: MAID02)

At September, 28 2009 I discovered a new main belt asteroid on a series of images of comet P/2008 O2 (McNaught).


Only through the collaboration between many observers of the world, the orbits of Minor Planets and Comets can be secured.
To be a small part of this global work of astromomers and amateurs makes me very happy and proud.

Behind every discovery or recovery of an object in space is standing an exiting story.
But the most important part of these extraordinary stories is the collaboration in friendship with like-minded guys around the world.

More new informations of the discovery of Minor Planet Maidbronn you find here, updated in July, 2015.

The original purpose of the photography was the measurement of the orbit of comet P/2008 O2 (McNaught).
But when blinking the images, I found two "new" objects close to the comet: MAID01 and MAID02                        GIF Animation
MAID01 (K09SH2G) is a recovery:
 2009 SG172 = 2003 UD373 = 2006 AE103. See: MPC 2009-T01 
MAID02 (K09SO2T) is a new object and my first named discovery. MAID02
= 2006 BN60 = 2009 ST242 = (410928) Maidbronn.

Antonio Garrigós Sánchez (B37) confirmed the object at September, 30 2009. Thanks a lot for this great work!
Also thanks to Josep M. Bosch (B74), the discoverer of the Apollo Asteroid and Near Earth Object (NEO) 2009 ST19,  who helped to make the contact to Antonio.
