Description
The Solar and Heliospheric Observatory (SOHO) Extreme-ultraviolet Imaging Telescope (EIT) has been taking images of the Solar disk and corona in four narrow EUV bandpasses (171, 195, 284, and 304 angstroms) at a minimum cadence of once per day since early 1996. The time series of fully-calibrated EIT images now spans approximately 28 years, from early 1996 to the early 2024, covering solar cycles 23 and 24 in their entirety, as well as the beginning of cycle 25. We have extracted Sun-as-a-star light curves in each of these four bands. I will present the results and discuss their implications for studies of activity on other stars, as well as the utility of UV observations for exoplanet detection and studies of exoplanet habitability.
