| 摘要 | Observations of a two ribbon flare on 5 May, 1989 were performed at Yunnan Observatory and at Meudon. Magnetograms have been obtained in Huairou-Beijing Observatory. The topology of the flaring region and the slow evolution of post-flare loops (cool flare loops) can be derived from Yunnan filtergrams. The ribbons seem to be the footpoints of the loops. The analysis of Ha line profiles in the loops, obtained with the Multichannel Subtractive Double Pass (MSDP) spectrograph of Meudon allows us to derive some physical parameters of the loops. The importance of the reference background intensity is discussed. The cool flare loops are low (h(max) approximately 25000km) dense (ne approximately 10(11) cm-3) and relatively inhomogeneous. They are rising with a velocity of 5 to 10 km s-1. |
