Progress with commissioning and science verification of ALMA

Construction and commissioning of the Atacama Large Millimeter/Submillimeter Array (ALMA) is progressing rapidly. Even with a fraction of the total number of antennas to be located at the Array Operations Site (AOS) in northern Chile in place, ALMA is the most powerful millimeter/submillimeter interferometer in the world. In this paper I report on the progress of array commissioning and science verification (CSV). I summarize the current performance of the array including noise temperatures, calibration accuracy and available observing modes. At the time of presentation of this paper, ALMA science verification observations will likely be available to the public. I will present the results and comparison data as well as update and detail the array status.
