Solar missions

I have been involved in multiple solar missions, either for scientific exploration, instrument calibration, or spacecraft/observatory operations.

Space missions:

EUI/Solar Orbiter

Extreme Ultraviolet Imager (EUI) is one of the six remote sensing payloads, aboard Solar Orbiter. It provides high resolution images of the solar corona and the chromosphere.

I am one of the co-investigators of EUI. My responsibility is to analyze high-resolution EUV images from the instrument to discover new details of the Sun.

SPICE/Solar Orbiter

Spectral Imaging of the Coronal Environment (SPICE) is an spectrometer, aboard Solar Orbiter. It provides spectroscopic diagnostics of various layers of the solar atmosphere.

I am involved in post-flight calibration of the SPICE data, specifically in calibrating of the Doppler signal.

IRIS

The Interface Region Imaging Spectrograph (IRIS) provides simultaneous UV imaging and spectroscopic data of the solar chromosphere and the transition region.

I served as IRIS's ESA appointed science planner for two weeks during 2022-2023. My responsibility was to plan and coordinate the science observations (as well as calibration tasks) of the instrument for the said period.

Ground observatories:

Kodaikanal Solar Observatory

It is one of the oldest solar observatories in the world and has archived regular solar images (in photographic plates/films) since 1904.

I was one of the key members in archiving the white-light images of the Kodaikanal observatory. I have led multiple science projects using the white-light sunspot data from this observatory (see the publication page) .
