(136849) 1998 CS1 в первой половине января 2009 года достигнет блеска 12.5 зв. вел., пролетая мимо Земли на расстоянии 0.03 а.е. Условия видимости будут не лучшими (сближение будет наблюдаться на утреннем небе), но благодаря положительному склонению будет вполне доступно для наблюдателей из севрного полушария.
