Estimated Total Execution Time (hours, including overheads)

2.8h (for one observation of every target; say 2h/night * 24 nights)

General Description

Repeat observations of bright O-type supergiants:  see 'time-critical
 aspects'.


All targets are too bright to need finders

Critical Observing Condition Constraints

None

Time-Critical Aspects

All targets available at any given time (or as many as possible) should
 be observed whenever conditions are too poor for other programmes, but at least
 once per week.

Not more than one observation (two integrations) of each target is needed each night.

OBs are grouped by "nights", allowing up to 25 obs/target

Special Execution Requirements

Exposure times are calculated for good conditions, and should be increased
 under poor transparency to maintain S:N of >100 in the continuum at H-alpha.

All targets are specified for two integrations per exposure.   This is just because
 exposure times are so short that double integrations are only a small increase in
 total time, but increase the S:N, and are useful for fixing cosmics.

Readouts can be conducted during slew to next target
