| 198450 Scattolin | Discovered 2004 Dec. 9 at the Jarnac Observatory, Vail. |
| Patrice Scattolin (b. 1965) is one of the foremost amateur observers in Canada. With Laurie Williams, daughters Clara and Sophie, and son Marc, the Scattolin family has worked tirelessly to motivate people to enjoy the sky. Clara's "Star Trek Observing List" is a groundbreaking effort to bridge the sky with science fiction. |
