SDSS J040714.78-064425.1 light curves

The light curves:


Red: SDSS J0407; Blue: the check star, shifted by +4 mag. The error bars are +/- the 1-sigma statistical uncertainties. The 4 spikes for the check star are due to the many geostationary satellites visible from my location in the direction of SDSS J0407.

13 Dec 2006: one measurement at mag 17.5, outside the eclipse, so the star is in a very low state.

14 dec 2006: 2 measurements at mag 17.7 and 17.6, outside the eclipse, so still in a very low state.



23 Dec 2006: one measurement at the eclipse.

24 Dec 2006: one measurement at mag 15.72.




The 2 peaks for the check star are due to satellite trails.
