They may be used for space weather forecasting or real time monitoring and display. They should not be used for scientific analysis, except perhaps to compare the quality of preliminary and definitive products. HMI space weather and quick-look products will be coordinated with the Heliophysics Events Knowledge Base. These data products will complement the AIA Quick Look Browse Products DRAFT LIST – This list is preliminary and is not a commitment. Each product must have a prospective user. Comments welcome!

ABSTRACT The Helioseismic and Magnetic Imager (HMI) will provide frequent full-disk magnetic field data after launch of the Solar Dynamics Observatory (SDO), currently scheduled NET November, megapixel line-of-sight magnetograms (Blos) will be recorded every 45 seconds. A full set of polarized filtergrams needed to determine the vector magnetic field requires 90 seconds. Quick-look data will be available within a few minutes of observation. Quick-look space weather and browse products must have identified users, and the list currently includes full disk magnetograms, feature identification and movies, 12- minute disambiguated vector fields in active region patches, time evolution of AR indices, synoptic synchronic frames, potential and MHD model results, and 1 AU predictions. A more complete set of definitive science data products will be offered about a day later and come in three types. ‘’Pipeline products,’’ such as full disk vector magnetograms, will be computed for all data on an appropriate cadence. A larger menu of ‘’On Demand’’ products, such as Non-Linear Force Free Field snapshots of an evolving active region, will be produced whenever a user wants them. Less commonly needed ‘’On Request’’ products that require significant project resources, such as a high resolution MHD simulation of the global corona, will be created subject to availability of resources.
