Razdow telescope A companion to the Kitt Peak Vacuum and McMath - Pierce Solar telescopes, the tiny Razdow used to
monitor sky conditions and warn observers inside the other two facilities of conditions that would degrade their observations.
Ice retreat depends strongly on the amount of solar heating of the surface ice and ocean; clear
sky conditions early in the melt season can go a long ways towards helping ice retreat later in the season, so this is one of the variables that will be
monitored closely (e.g., in the Barrow coastal sea ice break - up forecast, see below).
