Cooling Active Region Loops Observed With SXT and TRACE
An Impulsive Heating Multiple Strand (IHMS) Model is able to reproduce the observational characteristics of EUV (∼ 1MK) active region loops. This model implies that some of the loops must reach temperatures where X-ray filters are sensitive (> 2.5MK) before they cool to EUV temperatures. Hence, some bright EUV loops must be preceded by bright X-ray loops. Previous analysis of X-ray and EUV acti...
متن کاملActive Region Loops Observed with SUMER on board
We study the structure and dynamics of active region magnetic loops at transition region temperatures by analyzing high resolution observations of the active region NOAA 7962 at the limb on 1996 May 6. During the decay phase of a B-class are which occurred at the active region, the Solar Ultraviolet Measurements of Emitted Radiation (SUMER) spectrograph on board the Solar and Heliospheric Obser...
متن کاملDecaying post – flare loops system observed by SOHO / CDS and Yohkoh / SXT
The results of an analysis of joint SOHO/CDS and Yohkoh/SXT observations of a decaying post–flare loops system with a rapid time evolution are presented. The loop system was a remnant of a small single loop flare (GOES class C2.9). Using the CDS raster taken in several EUV lines with different formation temperatures and a temperature sensitive line pair Fe XVI 360.8/Si XII 520.7 we confirmed th...
متن کاملElectron temperatures of a late-phase solar active region from Yohkoh BCS and SXT observations
We deduce electron temperatures in a 2–3 month old active region from 1996 September and October, using soft Xray S xv spectra from the Bragg Crystal Spectrometer (BCS) and images from the Soft X-ray Telescope (SXT), both on board the Yohkoh satellite. Our observations cover a full transit of the region, from before its appearance around the east limb until after it disappeared around the west ...
متن کاملActive Region Loops and Microoares Seen by Sumer
A high resolution spectrograph observation of an active region at the limb, which was performed by Solar Ultraviolet Measurements of Emitted Radiation (SUMER) on board the Solar and Heliospheric Observatory (SOHO) on 1996 May 6, provides an unprecedented opportunity of studying the structures and dynamics of active region loops and microoares at transition region temperatures. The SUMER observa...
