Determining heating time scales in solar active region cores from AIA/SDO Fe XVIII images
Ignacio Ugarte-Urra, Harry P. Warren
We present a study of the frequency of transient brightenings in the core of solar active regions as observed in the Fe XVIII line component of AIA/SDO 94 A filter images. The Fe X…
The Absolute Calibration of the EUV Imaging Spectrometer on Hinode
Harry P. Warren, Ignacio Ugarte-Urra, Enrico Landi
We investigate the absolute calibration of the EUV Imaging Spectrometer (EIS) on Hinode by comparing EIS full-disk mosaics with irradiance observations from the EUV Variability Exp…
High Spatial Resolution Observations of Loops in the Solar Corona
David H. Brooks, Harry P. Warren, Ignacio Ugarte-Urra +1
Understanding how the solar corona is structured is of fundamental importance to determining how the Sun's upper atmosphere is heated to high temperatures. Recent spectroscopic stu…
