Dear Taichi,

Thought this message would be of interest regarding an outburst detection in 
2005 on V1047 Aql.

Regards,
Rod.

Rod's outburst observation of V1047 Aql arrived as the clouds here were
starting to break up.... I was able to obtain a 2.75hr times series 
photometry
run (unfiltered) on this star 25/Aug, 14:50-17:35 UT.  The resulting light
curve is an unmistakable superhump profile with 0.25 magnitude humps.

During the run 2 humps were captured - I estimate the period to be close to
0.074 days (107 minutes).  Magnitude is ~15.5R.

cheers,
Greg Bolt
