David,         Judging from the SXT data and the SEC reports, I'd lean towards either AR 8831 or AR 8833. Both are bright in SXT, the former a little moreso; SEC suggests that both have shown growth over the last few days, though with some simplification (see below).

        On 19-jan, AR 8831 will transit the central meridian, AR 8833 will still be ~1 day shy of transit; so both will be well placed for magnetography, AR 8831 a little moreso.

        As new data become available, I'll try to keep you updated about possible targets. Right now I favor AR 8831.
