Launched on September 2, 2023 and efficiently positioned in a halo orbit across the Sun-Earth Lagrange Point L1 in January 2024, Aditya-L1 is positioned 1.5 million kilometres from Earth. According to experiences, the mission goals to watch photo voltaic exercise and its impression on area climate. The findings associated to the CME have been printed in The Astrophysical Journal Letter by researchers from the Indian Institute of Astrophysics.
Observations of Coronal Mass Ejection
Reportedly, the researchers recognized a phenomenon often called coronal dimming, the place the brightness of the Sun’s corona decreased by almost 50 % within the affected area because of the ejection of photo voltaic materials. This dimming persevered for roughly six hours. The examine additionally recorded a 30% enhance in temperature and heightened turbulence within the area, marked by non-thermal plasma movement at a velocity of 24.87 km/s.
Plasma Movement and Magnetic Influence
Doppler velocity measurements indicated that the plasma was redshifted, transferring away from the observer at a velocity of about 10 km/s, as per sources. The CME’s trajectory was influenced by the Sun’s magnetic subject, which prompted a deflection within the motion of the ejected materials. This discovery underscores the significance of understanding magnetic forces in predicting the conduct of CMEs as they traverse interplanetary area.
These findings spotlight the important function of Aditya-L1 in unraveling the complexities of photo voltaic phenomena, paving the way in which for improved area climate predictions and advancing photo voltaic science.
