Full disk image at 17GHz (03:11:22UT).FOV of the box is 9.8' x 6.5'.

17GHz Mpeg movie of the box region.


Partial images in the box (R+L map). Red contour lines represent where Tb is 1.e4 and 1.e5(K), while
light blue contour lines where Tb of Stokes (L-R)-component is larger than 1.e5 (K).


Time evolution of the maximum brightness temperature at 17GHz in the box.
Solid line represents Max(R+V), while dash-dotted line Max(L-R).
Data points are plotted every 10 min.
