The Sudbury Neutrino Observatory is a heavy water Cherenkov detector designed to be sensitive to the total flux of Boron- 8 solar neutrinos. The addition of NaCl to the detector enhances the Neutral Current signal, and therefore improves the measurement of the total solar flux. The open salt dataset, consisting of approximately 254 days of livetime, has been analysed using analytic probabiltiy density functions in an extented maximum likelihood calculation. The final Boron-8 model constrained result of this analysis give a Charged Current to Neutral Current ratio of 0.344 +/- 0.021(stat) +0.024/-0.035(syst). This talk will present an overview of this independent analysis of the SNO data. Further, I will describe the current status of the experiment and provide a look at the possible future uses of the detector when the era of heavy water comes to an end in 2006.
