WMS Layers only take 4 parameters:
var GOES_ir = new OpenLayers.Layer.WMS(
                "GOES IR",
                
"http://mesonet.agron.iastate.edu/cgi-bin/wms/goes/east_ir.cgi?";,
                {
                        transparent: "TRUE",
                        layers: "east_ir_4km"
                },
                
                {singleTile: true, ratio: 1,
                 isBaseLayer: false,
                  opacity: 0.5}
        );

Works for me
