AAVSO Special Notice #127

Twilight observations of U Sco requested
October 15, 2008

Dr. Brad Schaefer requests evening twilight observations of U Sco
from our southern hemisphere observers for as long as is practical,
until U Sco disappears behind the Sun.  The campaign to monitor
the recurrent nova U Sco (Alert Notice #367, January 22, 2008)
continues, and observations of this object are needed.  U Sco
is a fast nova, and detection and confirmation of any nova event
need to occur over just a few hours if possible.  U Sco will be
nearly impossible for much of the northern hemisphere, but
southern observers may be able to continue observing in the early
evening twilight for a few more weeks.  All observations, including
"fainter-than" estimates are valuable, and please report all 
observations as soon as possible.  Any indication of 
outburst should be reported to immediately.
