# Measurements of HS 2331+3905 made at RIT Obs, Sep 30, 2007 UT, # made by Michael Richmond. # All data taken with 12-inch LX-200 + no filter + SBIG ST-8 CCD # no focal reducer, so at native f/10 # Each exposure 15 seconds long; tabulated times are midexposure # and accurate only to +/- 1 second. # 'mag' is a differential magnitude based on ensemble photometry # which has been shifted so TYC 3231-533-1 mag=10.900 # to match value from AAVSO Alert Notice 357. # # UT day JD-2,450,000 HJD-2,450,000 mag uncert Sep29.99851 4373.49851 4373.50304 13.931 0.032 Sep29.99881 4373.49881 4373.50334
