General Description

MIDI observations of the Nova V1280 Sco that suddenly fade in visible
 due to the formation of an important of dust within the ejecta.

The calibrator, HD150798, is bright (~100 Jy) and was chosen for its right ascension
 which is the same than the Nova, despite a low declibation (-69). This should ease
 the scheduling, considering that the two brigthest calibrator are 2h after and 1h30
 after the Nova.

The position of the nova should be accurate enough for the acquition. Its visual
 magnitude is now close to 11.5, at the center of the finding chart, hopefully bright
 enough to avoid a guiding star.

Final note: the MIDI brightness is difficult to evaluate from the K band current
 magnitude.
It should be close to the sensitivity limit. Since the dust is warm, the best acquisition
 filter is 8.7 micron.
