High-Speed Photometry of Lunar Occultations
JOA 2026, Vol. 16, No. 3, Page 32 Author(s): N. Wuensche,Abstract: Observations of lunar occultations are back. Decades ago, they were the almost exclusive focus of occultation observers before losing much of their scientific importance. This is now about to change. Many modern cameras used in astronomy are capable of recording at very high frame rates. Now even non-paid astronomers can perform high-time-resolution photometry of these events. We are talking about 5 ms per frame or faster. At resulting frame rates of 200 fps and above, it is possible to observe diffraction effects and to detect and measure binary and multiple star systems. The OLED project (OLED = Occultations Lunaires d’Étoiles Doubles (FR) or Occultaciones Lunares de Estrellas Dobles (ES)) is the first in many years to scientifically analyse lunar occultation observations. Observing lunar occultations is back!
