TL;DR
This study analyzes long-period solar brightness fluctuations by examining sunlight reflected from planets using LASCO C3 coronagraph data, revealing insights into solar oscillations.
Contribution
It introduces a novel method of studying solar oscillations through reflected planetary sunlight captured by the LASCO C3 instrument.
Findings
Identification of long-period brightness fluctuations in the Sun.
Correlation between planetary reflected light and solar activity.
New insights into solar oscillation patterns.
Abstract
We investigate the long-period fluctuations in the brightness of the Sun as a star using the measurements of sunlight reflected from the planets (Jupiter, Mars) when the light hits the field of view of the LASCO C3 coronagraph (Large Angle and Spectrometric Coronagraph Experiment).
