In Fall 2008 NASA selected a large international consortium to produce comprehensive automated feature-recognition system for the Solar Dynamics Observatory (SDO). The SDO data that we consider are all of Atmospheric Imaging Assembly (AIA) images plus surface magnetic-field from Helioseismic and Magnetic Imager (HMI). We robust, very efficient, professionally coded software modules can keep up with stream detect, trace, analyze numerous phenomena, including flares, sigmoids, filaments,...
Magnetic reconnection, the central engine that powers explosive phenomena throughout Universe, is also perceived as one of principal mechanisms for accelerating particles to high energies. Although various signatures magnetic reconnection have been frequently reported, observational evidence links particle acceleration directly site has rare, especially space plasma environments currently inaccessible $\textit{in situ}$ measurements. Here we utilize broadband radio dynamic imaging...

Abstract We investigate the topological evolution of coronal jet containing a sigmoid-like flux rope using nonlinear force-free field model obtained with flux-rope insertion method and magnetofrictional relaxation. examine predicted by unstable respect to observations from Solar Dynamic Observatory’s Atmospheric Imaging Array. also calculate squeezing factor, an approximation for sharp discontinuities in magnetic field, coiling rate, amount twist field. identify at least two features where...

HINODE's X‐ray Telescope (XRT) offers a unique combination of high spatial (≈2″) and thermal resolution, full‐Sun observations the solar corona over wide range temperatures (5.8∼<log T∼<7.6). We use multi‐filter Hinode/XRT data to explore thermal, statistical properties bright points (XBPs). have developed an automated XBP finder study BPs two periods during November 2007 May 2008. detect somewhat fewer XBPs than SOHO EIT in 195 Å but find comparable values 284 band. This is likely due some...
Polar plumes, plasma structures along open magnetic field lines in solar coronal holes, have long been thought to contribute the wind. The aim of this work is determine if eclipse and space‐based line intensity observations plumes may be used deviations from hydrostatic equilibrium can observed plumes. We obtained March 29, 2006 total Cape Coast, Ghana simultaneous filtergrams Extreme‐ultraviolet Imaging Telescope aboard Solar Heliospheric Observatory. developed a one‐dimensional...

The coronal magnetic Ąeld is the prime driver behind many as-yet unsolved mysteries: solar eruptions, heating, and wind, to name a few.It is, however, still poorly observed understood.We highlight key questions related energy storage, release, transport in corona, their relationship these important problems.We advocate for new multi-point co-optimized measurements, sensitive other plasma parameters, spanning from optical γ-ray wavelengths, bring closure long-standing fundamental questions.We...
