NORMAL POINTING UPDATE REQUEST 1-Jul-99

The purpose of this redefinition of the normal pointing is to move
the solar image 40" E on the CCD, ie S/C to the W by 40". This will
reduce the exposure at the NW limb, where SXT has been suffering
from dark-current artifacts.

1) please schedule OP+OG upload 
2) subsequent to the upload, please execute ROG #032 (dec)

********************************

The following shows the calculation for the new pointing coordinates.

1. Existing OG #032 is S/C W.279 N.385

2. Desired offpoint (TERM_REVIEW,/set) is 

Increment Euler angles (X, Y) by: 
      0.0000     -40.0 arc sec

3. Re-create old OG:
