A unique cyclonic and anti-cyclonic Eddies in Banda sea has been intensively studied using the data model from Infrastructure Development for Space Oceanography (INDESO) recorded from June 2010 to May 2011. According to our computational analysis, we found that the cyclonic of the Banda Sea happened in 12 days in January 2011. While the anti-cyclonic was observed as long as 111 days from June to September 2010.The unique phenomena were closely connected to 3 main factors: sea surface height, temperature, and salinity. The detail relationships among the physical parameters are discussed. This unique process of cyclonic and anti-cyclonic was happened during LaNina year in 2010 to 2011. This present work suggests that anti-cyclonic behavior of Banda sea during La Nina has a much longger time than that for cyclonic due to the meeting of 2 powerful currents from Indonesia Through Flow (ITF) coming from Halmahera sea, and Flores sea. Key words: Cyclonic, Anti-cyclonic, Eddy current, Banda Sea, INDESO model output.
