Dynamics and Kinematics of the EUV Wave Event on 6 May 2019
Ramesh Chandra, P. F. Chen, Pooja Devi +2
We present here the kinematics of the EUV wave associated with a GOES M1.0-class solar flare, which originates in NOAA AR 12740. The event is thoroughly observed with Atmospheric I…
Sympathetic Quiet and Active Region Filament Eruptions
Kostadinka Koleva, Pooja Devi, Ramesh Chandra +3
We present the observations of three sympathetic filament eruptions occurring on 19 July 2015 namely F1, F2, and F3. The events were observed in UV/EUV wavelengths by Atmospheric I…
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…
Observations of a prominence eruption and loop contraction
Pooja Devi, Pascal Démoulin, Ramesh Chandra +3
Context. Prominence eruptions provide key observations to understand the launch of coronal mass ejections as their cold plasma traces a part of the unstable magnetic configuration.…
Development of a Confined Circular-cum-parallel Ribbon Flare and Associated Pre-flare Activity
Pooja Devi, Bhuwan Joshi, Ramesh Chandra +3
We study a complex GOES M1.1 circular ribbon flare and related pre-flare activity on 26 January 2015 [SOL26-01-2015] in solar active region NOAA 12268. This flare activity was obse…
