Planet Hunt

These are the results for the most recent observations of our "phunt001" target that we obtained on the 22nd January 2007 and 17th February 2007. We want to check the previous results because we think a bright feature that appeared during your analysis of the 1st December 2006 observations might have been due to a thin cloud band covering the target during part of the night.

We noticed that some of you were using small apertures (circle radius) during the previous brightness measurements. If you can, try to use a circle radius in the region of 30 pixels.

Current Results for phunt001 (updated daily)

Optical brightness variation of phunt001 on 22/01/07 and 17/02/2007

The graph shows your results. The points give your averaged brightness results for phunt001, which have been calibrated using comparison star. The "bars" are Error Bars, which give us an idea of how uncertain the results might be. The variation seen relies on the comparison star being stable in brightness over the timeframe of the observations. Sadly, we have no additional star to ensure our comparison star is indeed stable.

The orbital phase relates to periodic brightness drop detected in the original SuperWasp survey. That dip occured every 2.17 days and phase zero relates to the centre of those dips. Thus 0.01 of phase equates to 0.01 x 2.17 = 0.022 days = 31 minutes.
