TRACE:	Report from Dan Seaton (dseaton@cfa.harvard.edu):
As of 23:00 EDT on 4/14, TRACE appears to be experiencing some difficulty,

no new images have been posted since early this weekend.  Nominally, the

TRACE plan for Monday and Tuesday is to support RHESSI, JOPs 104 and 137/

and observations at SPO as follows:

  0-7 UT  RHESSI, AR 9901/9893

 7-15 UT  JOP 137/104, AR 9900

15-19 UT  Sac Peak, AR 9899

19-24 UT  RHESSI, AR 9901/9893
Obviously, however, this plan is subject to change pending TRACE’s Monday

status and the development of solar activity throughout the day on Monday.
Please contact me with any further questions.
