| Abstract: | A new
instrument with a dual-beam Hα Doppler system is being developed at the Udaipur
Solar Observatory (USO)
in order to improve the quality and quantity of data on quiet, activated and
erupting filaments and prominences on the
Sun, especially those associated with geo-effective coronal mass ejections.
These data can be potentially used to construct three-dimensional topology of
erupting filaments as they leave the surface of the Sun and can be compared
with
multi-wavelength data obtained from space missions such as STEREO, SOHO and Hinode. The characterization of various optical
components for the instrument is being carried out, and some preliminary
results are presented in the paper. |
