Observations of Active Region Loops with the EUV Imaging Spectrometer on Hinode
Harry P. Warren, Ignacio Ugarte-Urra, George A. Doschek +2
Previous solar observations have shown that coronal loops near 1 MK are difficult to reconcile with simple heating models. These loops have lifetimes that are long relative to a ra…
Observations of Solar Doppler Shift Oscillations with the EUV Imaging Spectrometer on Hinode
John T. Mariska, Harry P. Warren, David R. Williams +1
Damped Doppler shift oscillations have been observed in emission lines from ions formed at flare temperatures with the Solar Ultraviolet Measurements of Emitted Radiation spectrome…
Observations of Transient Active Region Heating with Hinode
Harry P. Warren, Ignacio Ugarte-Urra, David H. Brooks +3
We present observations of transient active region heating events observed with the Extreme Ultraviolet Imaging Spectrometer (EIS) and X-ray Telescope (XRT) on Hinode. This initial…
Hinode EUV Imaging Spectrometer Observations of Solar Active Region Dynamics
John T. Mariska, Harry P. Warren, Ignacio Ugarte-Urra +3
The EUV Imaging Spectrometer (EIS) on the Hinode satellite is capable of measuring emission line center positions for Gaussian line profiles to a fraction of a spectral pixel, resu…
Eruption of a Kink-Unstable Filament in Active Region NOAA 10696
D. R. Williams, T. Toeroek, P. Demoulin +2
We present rapid-cadence Transition Region And Coronal Explorer (TRACE) observations which show evidence of a filament eruption from active region NOAA 10696, accompanied by an X2.…
