A new way to infer variations of the seismic solar radius
I. Gonzalez Hernandez, P. Scherrer, F. Hill
We show that the mean phase of waves propagating all the way from the far side of the Sun to the front side, as measured by seismic holography, varies with time. The change is high…
Magnetic field vector retrieval with HMI
J. M. Borrero, S. Tomczyk, A. Norton +5
The Helioseismic and Magnetic Imager (HMI), on board the Solar Dynamics Observatory (SDO), will begin data acquisition in 2008. It will provide the first full disk, high temporal c…
Imaging Spectroscopy of a White-Light Solar Flare
J. C. Martinez Oliveros, S. Couvidat, J. Schou +4
We report observations of a white-light solar flare (SOL2010-06-12T00:57, M2.0) observed by the Helioseismic Magnetic Imager (HMI) on the Solar Dynamics Observatory (SDO) and the R…
Magnetic field vector retrieval with the Helioseismic and Magnetic Imager
J. M. Borrero, S. Tomczyk, A. Norton +5
We investigate the accuracy to which we can retrieve the solar photospheric magnetic field vector using the Helioseismic and Magnetic Imager (HMI) that will fly onboard of the Sola…
