Group 1 - The research reveals a new pathway for the eruption of giant solar dark bars, based on observations from China's "Xihe" satellite and advanced imaging technology [1][2] - Giant solar dark bars can reach lengths of hundreds of megameters, equivalent to the radius of the sun, and their sudden eruption can lead to significant space weather events [2] - The study focused on a specific event on September 15, 2022, where a 350-megameter giant dark bar transitioned from a quasi-static state to an unstable eruption, triggered by smaller dark bars beneath it [2][3] Group 2 - Observations indicated that weak magnetic flux cancellation activities below the giant dark bar led to the formation and eruption of three small dark bars, which acted as a catalyst for the larger eruption [2] - The small dark bars, measuring only 10-20 megameters, created disturbances that ultimately triggered the sudden eruption of the giant dark bar [2][3] - The research provides important insights into the magnetic coupling processes between different scales of solar activity, highlighting the scientific value of high-resolution solar observations [3]
