47494 Gerhardangl           Discovered 2000 Jan. 4 by S. Sposetti at Gnosca.
Gerhard Dangl (b. 1959) is an amateur astronomer and teacher of electronics who lives with his wife Doris in Waldviertel, northern Austria. His main astronomical activity is the recording of asteroidal and lunar occultations with GPS-time-inserted video. He provides information about this technique to other astronomers.
