This module provides an environment variable with a unique identifier for each request. ... The unique identifier is even unique across multiple machines in a properly configured cluster of machines. ... On Unix machines, Apache creates several children, the children process requests one at a time. ... To distinguish time we will use a Unix timestamp (seconds since January 1, 1970 UTC), and a 16-bit counter. ... The actual ordering of the encoding is: time stamp, IP address, pid, counter. ...

This report describes what an HST observer must do to activate a Target of Opportunity proposal and the steps taken by STScI after the request is received. ... In the request the PI identifies which visit (or visits) to activate and supplies all the information needed to implement and schedule the observation on-board HST. ... If the activation request is not approved, you may re-request it at a later time, until the end of the observing cycle when unexecuted ToO observations are withdrawn. ...

I was wondering what conditions should be met to have the "darkest" sky .. ... Upon the above publication of the Southern Galactic hemisphere, TunГ Tezel started seeking opportunities to create the Northern counterpart image. ... So, the initial quest of having the darkest possible sky have delivered us these two all-sky images of the two galactic hemispheres as seen from Planet Earth.
