Eruption 2010-01-08 – Observations are top priority

The recurrent nova U Sco erupted on 2010 Jan 28th at mag 8.8. A week later it faded to V=11.5. Only seven recurrent novae (NR) are listed in the GCVS, and this one exhibits total eclipses. Because of the crucial importance of this rare class of star to understanding the mechanisms underlying novae and Type 1a supernovae, the importance of this eruption is hard to exaggerate. Visual, PEP/CCD time series and colour observations are requested by AAVSO; and CCD time series observations by CBA where they will be made immediately available to Brad Schaefer’s campaign team. Please observe this star as your top priority.
