The "missing quadrant" problem which GRIM2 has displayed intermitently in the past has returned and has been very severe recently, making the instrument nearly unusable for the past couple of nights. Consequently the instrument is being taken out of service for attempted repairs until further notice. GRIM2 is next scheduled contingently (i.e., along with another instrument) until Oct 23 and is not the exclusive scheduled instrument again until Nov 3. Return of the instrument to service by those dates will be attempted, of course. Updates will be posted to apo35-general.
