# Sonneberg plate photometry for Boyajian's Star in two passbands

**Tabby's star (KIC 8462852)** Articledoi: **[10.3847/1538-4357/aa615d](https://doi.org/10.3847/1538-4357/aa615d)** 0

## What it's used for here

Independent plate archive (Sonneberg Sky Patrol, 1934-1995): 861 pg and 397 pv magnitudes, differential against 39 colour-matched comparison stars. Combined slope -0.006 +/- 0.032 mag per century; rejects 0.164 at 4.9 sigma. Also Sternberg (Moscow) plates 1895-1995: -0.046 +/- 0.040. Key evidence against a real century fade and against a 1955-65 drop.
