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 aavso@aavso.org immediately. For more information about this campaign, please see the text of Alert Notice #367 at the following URL: http://www.aavso.org/publications/alerts/alert367.shtml A page about the campaign has also been established here: http://www.aavso.org/news/usco.shtml U Sco is located at RA 16:22:30.8 Dec -17:52:43 (J2000) Custom charts and comparison star photometry tables for U Sco may be generated with VSP at the following URL: http://www.aavso.org/observing/charts/vsp/index.html?pickname=u%20sco Recent observations for U Sco are available at the following URL: http://www.aavso.org/cgi-bin/newql.pl?name=u%20sco&output=html Please report all observations promptly to the AAVSO as "U SCO".
