The temperature map of the loop and coronal sources of an occulted flare View all abstracts by submitter

An occulted flare occurred at about 06:07 UT on 2002 November 2. The RHESSI X-ray images show two separate parts. The lower part consists of a complete loop and the upper part a coronal source which well extends above the solar limb. The loop source shrank for about 3 minutes with a speed of ??24 km s-1 during the early impulsive phase and then expanded at ??7 km s-1, while the coronal source presented an upward motion at about 6 km s-1. We got the temperature map of the two sources from RHESSI image spectrum. The temperature of the loop increases with altitude, while for the coronal source the temperature decreases with altitude. These results indicate that the reconnection X-point of this flare is located between the looptop source and the coronal source.
