Solar transition region above sunspots
H. Tian, W. Curdt, L. Teriaca +2
We study the TR properties above sunspots and the surrounding plage regions, by analyzing several sunspot spectra obtained by SUMER in March 1999 and November 2006. We compare the…
Propagating waves in polar coronal holes as seen by SUMER and EIS
D. Banerjee, L. Teriaca, G. R. Gupta +3
To study the dynamics of coronal holes and the role of waves in the acceleration of the solar wind, spectral observations were performed over polar coronal hole regions with the SU…
Dynamics and evolution of an eruptive flare
L. Teriaca, A. Falchi, R. Falciani +2
We study the dynamics and evolution of a C2.3 two-ribbon flare, developed on 2002 August 11, during the impulsive and the long gradual phase. To this end we obtained multiwavelengt…
SUMER observations of the inverse Evershed effect in the transition region above a sunspot
L. Teriaca, W. Curdt, S. K. Solanki
Aims. We analyse SUMER spectral scans of a large sunspot within active region NOAA 10923, obtained on 14-15 November 2006, to determine the morphology and dynamics of the sunspot a…
The Ly-alpha profile and center-to-limb variation of the quiet Sun
W. Curdt, H. Tian, L. Teriaca +2
We study the emission of the hydrogen Lyman-a line in the quiet Sun, its center-to-limb variation (CLV), and its radiance distribution. We also compare quasi-simultaneous Ly-a and…
Search for photospheric footpoints of quiet Sun transition region loops
J. Sanchez Almeida, L. Teriaca, P. Suetterlin +3
CONTEXT:The footpoints of quiet Sun Transition Region (TR) loops do not seem to coincide with the photospheric magnetic structures appearing in traditional low-sensitivity magnetog…
