Correlations with Magnetic Activity in the Solar Near-Surface Shear Layer. II. Radial Shear
M. Cristina Rabello Soares, Sarbani Basu, Richard S. Bogart +1
Using Helioseismic and Magnetic Imager ring-diagram measurements and building on the rotation-rate inferences presented in Paper I for depths of 1-17 Mm, we examine the propert…
Stray Light Correction for the Helioseismic and Magnetic Imager
A. A. Norton, T. L. Duvall, J. Schou +6
We report a point spread function (PSF) and deconvolution procedure to remove stray light from the Helioseismic and Magnetic Imager (HMI) data. Pre-launch calibration observations,…
Evidence of a Quasi-periodic Global-scale Oscillation in the Near-Surface Shear Layer of the Sun
Richard S. Bogart, Charles S. Baldner, Sarbani Basu +2
We present evidence of hitherto undiscovered global-scale oscillations in the near-surface shear layer of the Sun. These oscillations are seen as large scale variations of radial s…
On-Orbit Performance of the Helioseismic and Magnetic Imager Instrument onboard the Solar Dynamics Observatory
J. Todd Hoeksema, Charles S. Baldner, Rock I. Bush +2
The Helioseismic and Magnetic Imager (HMI) instrument is a major component of NASA's Solar Dynamics Observatory (SDO) spacecraft. Since beginning normal science operations on 1 May…
Evolution of Near-surface Flows Inferred from High-resolution Ring-diagram Analysis
Richard S. Bogart, Charles S, . Baldner +1
Ring-diagram analysis of acoustic waves observed at the photosphere can provide a relatively robust determination of the sub-surface flows at a particular time under a particular r…
An investigation of CME dynamics, productivity and source-region subsurface structure
Chia-Hsien Lin, Charles S. Baldner, James Chen
This work is to study the dynamics of coronal mass ejections and to investigate possible correlation between CME productivity and subsurface structure. Two CMEs and six active regi…
