\n\t"20th May 2013 marks the 150th anniversary of the first recorded outburst of

\n\tdetected U Sco at mag 9.1. Within 8 days it had faded to mag 12.4 and then
\n\tdisappeared. Pogson had only recently defined the modern magnitude scale
\n\tand his observations of U Sco in 1863 are remarkably similar to the outburst
\n\ttemplate derived from later eruptions by Schaefer in 2008. The discovery
\n\tof U Sco was just 7 years after Pogson had confirmed the recurrent nature of
\n\tU Gem the first dwarf nova. Pogson was also the first observer to report
\n\tflickering in a dwarf nova (U Gem again). So CV fanatics have plenty to
\n\tthank Pogson for and ought to take a little time out tomorrow (20th May)to
\n\tthink about this remarkable Victorian visual observer." <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
