Ground-based photometry of bright stars is expected to be limited by atmospheric scintillation, although in practice observations are often other sources systematic noise. We analyse 122 nights star ($G_{mag} < 11.5$) using the 20-cm telescopes Next-Generation Transit Survey (NGTS) at Paranal Observatory Chile. compare noise properties theoretical models and we demonstrate that NGTS indeed scin...
