1. The size and intensity of the halo remained almost constant in the range of 10 Mm2. However, the core area was very compactand expanded rapidly from about 1 Mm2 to 4 Mm2.

2. The halo contrast increased by about 8% compared to the flare-quiet region, which is close to the most current simulation (13%)byCheng et al. 2010.

3. Scheduled fast mode observations, ~150 fps, 4000 ~ 9000 Å
