Dear group,
One of the most recognized pulsating variable stars is RR Lyrae. Discovered
in 1901, it is used as a "standard candle" for studies involving globular
clusters amongst others.
It fluctuates by almost a full magnitude every 13.60 hours. However, being a
summertime object, it is impossible to pursue a light curve during one
session. With some strategic planning, we can do something over two
all-nighters:

================================================== ==
Perhaps you should record it from both Athens and Anchorage
continuously for a month with some strategic planning. Only
cloud will prevent it, Your colleague in Anchorage can overlap
every 12 hours.

Actually a friend runs a very serious operation in Arizona involving premium equipment and he has kindly offered me access to the facility. He is expecting a one-meter scope this fall and he very kindly offered me (remote) access to it.
This is a godsend since such work could use continuous monitoring from multi-continent facilities. This is what the pros do with many of their studies..
Anthony.
