HMI Space Weather and Quick-Look Browsing Products
Generally HMI space weather and quick-look browsing products are those computed in near real time from quick look SDO data. 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
[Older material...]
This proposed list is very much in preliminary form and should not be taken as a commitment.
Each product should have a prospective user.
Comments welcome.
