Results from the same event from Camalaú, Paraíba, approximately south (and on what was predicted to be the very southern extent of the shadow path), showed a 28-second occultation, corresponding to an approximately chord, much longer than might otherwise have been expected. However, Quixadá, south of São Luís–between it and Camalaú–paradoxically had a negative result. To account for the negative Quixadá results, the apparent oblateness (flattening) of Varuna was imposed at a minimum value of approximately 0.56 (aspect ratio "c"/"a" ≤ 0.44), corresponding to a minimum polar dimension of approximately , based on the given chord length of . The resulting lower bound on Varuna's polar dimension is approximately equal to Lacerda and Jewitt's lower bound "c"/"a" aspect ratio of 0.45, which they previously calculated in 2007. A preliminary conference presentation, given before the Camalaú results were fully analyzed, concluded that the São Luís and Quixadá results together suggested a significantly elongated shape is required for Varuna.
