13858 Ericchristensen           Discovered 1999 Dec. 5 by CSS at Catalina.
Eric Christensen (b. 1977) is survey operations manager with Catalina Sky Survey. He has developed many novel tools to aid observers in validating the reality of moving objects flagged by CSS software, and created the catalog of stationary objects used by the Catalina Real time Transient Survey to identify optical transients.
