12.82R
Check star:    USNO-A2.0 0825-09353329 (16:25:42.04 -03:53:28.1) with  
12.18R
Integ time:     60s
Instrument:    0.25 m reflector f/4.8
Camera:        QSI-516ws
Filter:             Clear
Observatory:  Huelva (Spain)
Comments:     Very good weather conditions.
               Run covering about 2h 30m. The first minima happens
               at the very begining of the run. This is included below
               with an uncertainty estimated as 2 min.
               A second minima is also captured close to the end
               of the run.
               Times of minima of the eclipses are:

               Note that heliocentric corrections have not been applied.
               Using linear regression I find

                    JD = 2455286.67924 + 0.081053 * E

               Average magnitude 15.74(15) assuming mag(comp)=12.82
               (which is the R mag of the comp according to USNO-A2.0.
               This is 0.16 mag fainter than run03
