A small (arcade?) flare occurred at the SW limb,
following an M3.7 flare at 21h UT on Oct. 26.

Type III and II bursts were observed by HiRAS/CRL around 04:30UT.


FOV of the box is 461" x 491".


Time evolution of the maximum Tb.
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 large box. The source expanded horizontally at a height.
The brightness is normalized to the maximum Tb in each image.
Orange contours show RCP source and red contour indicates where Tb = 1.e4 K.
Mpeg movie (10 min. interval)



Yohkoh SXT (AlMg filter) image of the target region observed on Oct 27, 1999.
FOV is the same as that of the above NoRH partial images (491" x 491").


Type III and II bursts were observed by HiRAS/CRL, associated with the C5.3 flare.
