Give longer warning times for solar geoeffective disturbances via local, very high precision nearside helioseismology to forecast emergence of magnetic flux from below the solar surface that can coalesce into solar active regions and lead to solar geoeffective disturbances. NASA’s Solar Dynamics Observatory (SDO), launched in 2010, enables this objective with high-resolution solar observations at a nearly continuous science data downlink rate of 130 Megabits/sec.
- Link NRL ocean acoustic wave propagation modeling and analysis techniques with solar physics expertise to a new frontier of solar space research: to explore local solar nearside detection of magnetic flux below the Sun’s surface before it emerges, by analyzing solar surface Doppler observations
- Obtain data for this analysis from the Helioseismic & Magnetic Imager (HMI) on the geosynchronous orbit SDO satellite, and also from the Michelson Doppler Imager (MDI) data from the Solar & Heliospheric Observatory (SOHO) that was launched in 1996 and is providing ongoing data from L1
- Modify and apply acoustic wave HPC tools developed primarily for naval acoustics to solar flux emergence prediction, and regressive classifier approach prediction methods that are used also for ocean research acoustics topics
- Nearside helioseismology inverts acoustic wave patterns observed on the Sun’s nearside due to rays that have propagated a short distance below the solar surface, and have interacted with regions of magnetic flux in the process of emerging.
- With local high-precision nearside helioseismology, solar active regions and sunspots may be detectable at very early stages in development, towards highly accurate space weather prediction
