PERIOD COVERED:  0000Z (UTC) 04/30/96 - 0000Z (UTC) 05/01/96

Daily Status Report as of 122/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed GHRS/2 6072 (The First Multiple Layer Doppler Imaging of =
an Active Binary)

       The High Resolution Spectrograph (Side Two) was used to make the =
first rapid mode multiple layer Doppler imaging of the active binary =
system HD155555 (aka, V824).  This target was observed in wavelengths of =
Mg II and C IV in order to construct a two-dimensional map of the uneven =
heating distribution in the choromosphere.  A wavelength calibration =
image was also taken.  Twenty-four hours into this 39 hour proposal, the =
loss of lock reported in 2.3 occurred.  Otherwise, the observations were =
executed as scheduled, and no further anomalous activity was noted.

                            Scheduled Acquisitions : 4
                                        Successful : 4

                          Scheduled Reacquisitions : 7
                                        Successful : 7

   2.2 FHST Updates: 

                              Scheduled : 0
                             Successful : 0




   2.3 Loss of Lock:

       As reported in HSTAR 5589, there was a one minute loss of lock =
that started at 122/0054Z.

   2.3 Operations Notes: 

       No operational problems were reported.

3.0 SIGNIFICANT FORTHCOMING EVENTS: 

        GSFC Internal Simulation #4 (EVA #2) will be conducted on =
Thursday from approximately 8:00 a.m. until approximately 6:00 p.m..
