We have obtained optical spectra and IR photometry in an attempt to determine the orbital parameters of the Aql X-1 system. Spectra from the MMT in October 1995 appear to detect the secondary, but are not sufficient to measure the mass function. IR photometry in and out of mini-outburst find K ~ 15.4, and may indicate that the disk contributionat K is modest during the mini-outburst.
