We will continue these observations until approximately 17:20 on 13-May, when we begin making observations for JOP 080. The southern active region NOAA 8218 has been chosen as the target for that JOP; at the completion of JOP 080, JOP 059 will continue with NOAA 8218 as its new target. SXT's support of JOP 059 on 8218 will probably be in the form of 2-minute cadence observations, as no uplinks will be possible between the end of JOP 080 and the end of JOP 059.

Between 17:57:23 and 17:59:01 SXT observed a localized transient brightening. The images below show the location of this brightening and its light curve (click to see a larger image).
Unfortunately this is not precisely the same region being targeted by TRACE and CDS -- they're pointing further south. It was judged that due to the faintness of X-ray emission closer to the limb, SXT would not be able to make contributions of any real value at that location. (Click to see a larger version.)
Next, here's a representative image from the fast-cadence run. The run resulted in two sets of images: a set of full-resolution (2.5 arcsec) images at 32-second cadence from 15:41:57 to 16:09:47 UT, and a set of half-res (4.9 arcsec) images at 64-second cadence from 16:11:19 to 16:37:11 UT. The full-res images are made with an exposure length of 2.7 seconds. (Click for larger image.)
The smaller image has been decompressed, exposure normalized, and dark-current subtracted. Peak brightness in the northern set of loops is about 125 DN. The bright spot in the southern set of loops is an artifact.
