SLIDE 7 Early HMI Magnetic Field Observations
HMI Space Weather and Quick-Look Browsing Products
- HMI space weather and browse products can be computed in near real time from quick look 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
- Proposed Space Weather Product LIST – Comments welcome! This list is preliminary and is not a
- commitment. Each product must have a prospective user.
