Subject: Upcoming Exoplanet Transit..
Hi Folks;
If your looking for a photometric challenge, check out the Exoplanet "HD189733 b" which is about 30 arc minutes east of M 27. Details on it are at:
http://var2.astro.cz/ETD/etd.php?STARNAME=HD189733&PLANET=b
and
http://var2.astro.cz/ETD/predict_detail.php?STARNAME=HD189733&PLANET=b&PER=&M=
Hubble and Swift have been measuring the changes in the Exoplanet's atmosphere, as described here:

For us, exoplanet "HD189733 b" (orbiting star HIP 98505 Magnitude 7.65) will start a Transit on July 12 at 07:32 UTM and end at 09:22 UTM. The dip in brightness will be 0.0282 magnitudes and there are 2 adjacent stars of reasonable close brightness (mag 8.1 and 8.93) for using as comparison stars.
PS: Have a safe, happy and relaxing 4th of July..
