On February 12, XRT was observing a little active region on the Sun using the Thin-Be 
filters to see hotter plasma (> 2MK).  This active region lights up in many different 
ways.  It connects with its neighboring little bright points, a large loop over lying the 
initial structure lights up then fades away.  Then there seems to be a j or an S shape 
that appears for a few minutes and then dissapears.  It is a very complicated region.
