Empirical atmosphere model in a mini flare during magnetic reconnection
Brigitte Schmieder, Reetika Joshi, Ramesh Chandra +6
A spatio-temporal analysis of IRIS spectra of MgII, CII, and SiIV ions allows us to study the dynamics and the stratification of the flare atmosphere along the line of sight during…
Solar jets observed with the Interface Region Imaging Spectrograph (IRIS)
Brigitte Schmieder, Reetika Joshi, Ramesh Chandra
Solar jets are impulsive, collimated plasma ejections that are triggered by magnetic reconnection. They are observed for many decades in various temperatures and wavelengths, there…
Filament Eruption Driving EUV Loop Contraction then Expansion above a Stable Filament
Ramesh Chandra, Pascal Demoulin, Pooja Devi +2
We analyze the observations of EUV loop evolution associated with the filament eruption located at the border of an active region. The event SOL2013-03-16T14:00 was observed with a…
Balmer continuum enhancement detected in a mini flare observed with IRIS
Reetika Joshi, Brigitte Schmieder, Petr Heinzel +3
Optical and near-UV continuum emissions in flares contribute substantially to flare energy budget. Two mechanisms play an important role for continuum emission in flares: hydrogen…
Fine Structures of an EUV Wave Event from Multi-Viewpoint Observations
Ramesh Chandra, P. F. Chen, Pooja Devi +3
In this study, we investigate an extreme ultraviolet (EUV) wave event on 2010 February 11, which occurred as a limb event from the Earth viewpoint and a disk event from the STEREO-…
Variation of Chromospheric Features as a Function of Latitude and Time using Ca-K Spectroheliograms for Solar Cycles 15-23: Implications for Meridional Flow
Pooja Devi, Jagdev Singh, Ramesh Chandra +2
We have analysed the Ca-K images obtained at Kodaikanal Observatory as a function of latitude and time for the period of 1913 - 2004 covering the Solar Cycle 15 to 23. We have clas…
