Successive R-polarized flares at the SW limb.


FOV of the box is 589" x 982".


Time evolution of the maximum Tb in the full-disk (upper) and in the box (lower),
The solid line shows Max (R+L) and the dotted line shows Max (R-L).
Data points are plotted every 10 min.


Stokes I (R+L) map in the box taken during the two flares. The brightness is normalized to the Max Tb in each image.
Mpeg movie (10 min. interval)


Hard X-ray sources of the two flares.
Yohkoh/HXT L-channel images synthesized at 01:47-01:48UT (left) and at 04:42-04:43UT (right).
