Data:
  • Observer: Simonluca Landi
  • Created: 10/1/2026, 13:18 UTC
  • Station: Private observatory, Lombardy, Italy
    Lat: +46°, Long: +09°
  • Instrument: RC 203 mm + TS 0.67x reducer (f/5.6), IMX571 mono, Baader Sloan filters
  • Photometric band: Sloan r'
  • Time standard: BJD_TDB
  • Brightness in: Mag
Note:
Forced aperture photometry (position from WCS) on co-added runs of 2-3 x 10 s frames; ensemble of ~150 Gaia DR3 GSPC comparison stars (synthetic SDSS). Untransformed. Absolute level uncertain by ~0.05-0.1 mag (position-dependent illumination correction outdated); timing unaffected. Our own fit of this secondary minimum (symmetric polynomial, bootstrap errors): BJD_TDB 2461312.37257 +- 0.00195 d.
