Exoplanet Transit HAT-P-5b in Lyra (13 mmag depth)

Anthony,

I attempted imaging a binary EKBO (V=17.4) expected to undergo a mutual eclipse lasting several hours and centred on May 31 01:40+/-1:00 UT.

Basically, the idea is whole night unfiltered photometry ( sample every minute or every few minutes) is all that was required. Unfortunately, I was clouded out during the last part. I have no dip to show the transit.
This would have been its first of many transits since discovery. So, it is an important observation to determine the size of it's moon.

There are also future opportunities in June and July.

I'm not to sure if this is a challenge for your set up.

Hi Eamonn,

Thanks for the heads-up and most interesting lead. However, I have a serious problem and this has to do with the baseline magnitude which will cause me serious problems in relation to SNR.

My exoplanet work has involved exoplanets as dim as 12.5 magnitude ... I have a target parent star with exoplanet whose magnitude is 13.5 and which will be my next major test in relation to the dimness of the parent star. However, I am 99.9% sure that the mag 17+ you describe for the asteroid is out of my reach. Of course, it does not hurt to sit down and confirm my suspicions.

Thanks once again for the lead!!!
