Variation of Emission Line Width in Mid- and High-Latitude Corona
S. Krishna Prasad, Jagdev Singh, D. Banerjee
Spectroscopic studies of the solar corona, using the high spatial and spectral resolution 25-cm coronagraph at the Norikura observatory for equatorial off-limb observations, indica…
Oscillations in active region fan loops: Observations from EIS/{\it Hinode} and AIA/SDO
S. Krishna Prasad, D. Banerjee, Jagdev Singh
Active region fan loops in AR 11076 were studied, in search of oscillations, using high cadence spectroscopic observations from EIS on board Hinode combined with imaging sequences…
Propagating intensity disturbances in polar corona as seen from AIA/SDO
S. Krishna Prasad, D. Banerjee, G. R. Gupta
Polar corona is often explored to find the energy source for the acceleration of the fast solar wind. Earlier observations show omni-presence of quasi-periodic disturbances, travel…
