Special Notice #197: Request for time-series photometry of U Sco

March 2, 2010: Dr. Bradley Schaefer (LSU) requests intensive time-series observations of U Scorpii beginning immediately and continuing through 2010 March 4 08:00 UT (JD 2455259.83). These observations are requested in support of coincident X-ray photometry by the XMM-Newton satellite. The XMM-Newton observations, requested by Dr. Jan-Uwe Ness (ESA), will investigate the X-ray behavior of U Sco during its transition from outburst back to quiescence.

Special Notice #380: Reported outburst of the recurrent nova V0745 Sco

February 6, 2014: Rod Stubbings (observer code SRX; Tetoora Road, Victoria, Australia) reports an outburst of the recurrent nova V0745 Sco (aka Nova Sco 1937). Stubbings reports the nova at a visual magnitude of 9.0 on 2014 February 6.694 UT (JD 2456695.194).
