10. 2010 March 10 Fast mode flare observations 1.The size and intensity of the halo remained almost constant in the range of 10 Mm 2. However, the core area was very compact and expanded rapidly from about 1 Mm 2 to 4 Mm 2. 2. The halo contrast increased by about 8% compared to the flare- quiet region, which is close to the most current simulation (13%)by Cheng et al. 2010. 3. Scheduled fast mode observations, ~150 fps, 4000 ~ 9000 Å
