We present an observation of t t production in the dilepton decay channel using the CDF detector at the Fermilab Tevatron Collider. This measurement w as made using 67 pb 1 of data, 19.3 of which w as taken during the 1992-93 data run while the remaining data has been acquired this past year (94-95). We observe 6 e v ents in the t t signal region with an expected background of 1.3 0.3 events. This signal is inconsistent with the background prediction by 2.7. Additionally, three of these events
