We obtained images and spectra of Venus for 10 consecutive nights from the NASA Infrared Telescope Facility with SpeX in July and August of 2007. Our continuum K observations cover the 2.26 micron atmospheric window and show the lower clouds on Venus backlit by the thermal radiation from the lower atmosphere. As our data were taken so close to inferior conjunction we see up to 90% of the night side of Venus in each image. This allows for a longer tracking of individual clouds as they cross the nightside than previous data sets allowed. We are also able to track features from about -60 to +60 degrees latitude which complements and extends the VIRTIS data set from Venus Express. VIRTIS typically targets latitudes from -10 to -90 degrees. We will present zonal wind profiles for the north and south, for winds at approximately 50km altitude. Understanding zonal wind profiles at these altitudes is an important aspect of understanding Venus' general circulation and the atmosphere's superrotation.
