Exoplanet Observations in 2007
obtained at CBA Belgium Observatory 

 
Below is a sample of my Exoplanet observations made in 2007.
 

GJ 176
 
A possible transit of GJ 176 was predicted on 15 Sep 2007. I made R-band photometric observations around the expected egress time, but as the light curve below shows, there was no sign of a transit down to 2 mmag.

WASP-1b
 
 
 

WASP-2b



HAT-P-1b


Ingress and egress of HAT-P-1b were early by approx. 15 minutes compared to the ephemeris elements published in the HAT-P-1 discovery paper. I'm not completely satisfied with the photometric accuracy. I guess that my observations did suffer from not using a filter (I was using my other telescope with filterwheel on a different target that evening).
