The Helioseismic and Magnetic Imager (HMI) on the Solar Dynamics Observatory (SDO) is beginning to produce a synoptic series of full-disk arc-second resolution magnetograms. Line-of-sight magnetograms are available every 45 seconds and the vector field will be routinely calculated every 12 minutes in automatically identified active region patches. Select quick-look products are available within minutes and definitive science data will be published within a day or two. The larger team has developed programs to routinely produce a comprehensive set of higher level products, including synoptic maps and frames, local surface-flow maps, a variety of local and global coronal field models, and time series of tracked active-region parameters - all useful in learning to forecast space weather events. Comparisons with AIA, EVE, MDI, SOLIS and other ground-based observations will ultimately help understand uncertainties in the observations. This work was supported by NASA through contract NAS5-02139 to Stanford University.
