About this award
This is a $133,088.88 grant award from the National Aeronautics and Space Administration (NASA) to the Association of Universities for Research in Astronomy, Inc. (AURA), a non-profit organization that manages astronomical observatories and telescopes. The grant is for research related to systematic errors in physical quantities calculated from the Solar Dynamics Observatory's (SDO) Helioseismic and Magnetic Imager (HMI) filtergrams, specifically in line-of-sight Doppler velocity, line-of-sight magnetic field, and vector magnetic field measurements. The research aims to understand and correct these small but important systematic errors, which hinder certain analyses of solar dynamics and energy/helicity transport. This grant award is not associated with a set-aside contract and was made directly to AURA, which has a history of conducting astronomical research and operating observatories under grants and contracts with NASA and other federal agencies.
Description
The physical quantities calculated from HMI filtergrams exhibit small but important systematic errors related to the SDO orbital velocity that show up in line-of-sight (LOS) doppler velocity v, LOS magnetic field m, and the vector field b. Results show a c. 1% not-quite-linear scale error in velocity and somewhat larger 24- and 12-hour periodic variations in reported magnetic field values. Though small they are systematic and hinder some analyses of some solar quantities that depend on frame-to-frame differences in the reported magnetic field such as energy and helicity transport through the
