High Resolution Observations using Adaptive Optics: Achievements and Future Needs
K. Sankarasubramanian, T. Rimmele
Over the last few years, several interesting observations were obtained with the help of solar Adaptive Optics (AO). In this paper, few observations made using the solar AO are enl…
The solar chromosphere at high resolution with IBIS. I. New insights from the Ca II 854.2 nm line
G. Cauzzi, K. P. Reardon, H. Uitenbroek +7
(Abridged) Aims: In this paper, we seek to establish the suitability of imaging spectroscopy performed in the Ca II 854.2 nm line as a means to investigate the solar chromosphere a…
The discrepancy in G-band contrast: Where is the quiet Sun?
Han Uitenbroek, Alexandra Tritschler, Thomas Rimmele
We compare the rms contrast in observed speckle reconstructed G-band images with synthetic filtergrams computed from two magneto-hydrodynamic simulation snapshots. The observations…
Detection of opposite polarities in a sunspot light bridge: evidence of low-altitude magnetic reconnection
Lokesh Bharti, Thomas Rimmele, Rajmal Jain +1
A multi-wavelength photometric analysis was performed in order to study the sub-structure of a sunspot light bridge in the photosphere and the chromosphere. Active region NOAA 8350…
Solar Atmospheric Oscillations and the Chromospheric Magnetic Topology
A. Vecchio, G. Cauzzi, K. P. Reardon +2
We investigate the oscillatory properties of the quiet solar chromosphere in relation to the underlying photosphere, with particular regard to the effects of the magnetic topology.…
Solar Site Survey for the Advanced Technology Solar Telecope. I. Analysis of the Seeing Data
H. Socas-Navarro, J. Beckers, P. Brandt +17
The site survey for the Advanced Technology Solar Telescope concluded recently after more than two years of data gathering and analysis. Six locations, including lake, island and c…
