摘要

摘要: Two groups of microwave type U and Reverse-Slope (RS) bursts after the Soft X-Ray (SXR) maximum were observed with the 2.6～3.8GHz spectrometer of Chinese Solar Broadband Radio Spectrometers (SBRS/Huairou) on 15 February 2011, when an X2.2 solar flare occurred in the Active Region (AR) NOAA11158. A Shear-driven Quadrupolar Reconnection (SQR) model was utilized to analyze these bursts and the two loops involved were found to be basically in the same spatial scale and have a height difference of about 1300km. These bursts were interpreted to be a result of a new reconnection process between the two similar-scaled loops.
