Lunar occultation of Saturn and Titan

On the morning of March 29, the Moon will occult Saturn and its system of satellites. The table below gives the times of first contact (A - D) and last contact (E - H) of the rings (A, D, E, H) and planetary limb (B, C, F, G), with the Moon. The time of disappearance of Titan is also listed. The upper diagram shows the approximate configuration of the satellites Mimas (M), Dione (D), Enceladus (E), Tethys (T), Rhea (R) and Titan.
