EIT: Nominal. Half-resolution 195 CME watch and synoptics. MDI: Nominal. Full disk magnetograms and dopplergrams for continuous contact, supporting Sac Peak campaign. 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.
