The occultation of 31 July 2009 was visible in much of southern Asia and the Middle East. [37] [38] Every year around December 2 the Sun passes 5° north of Antares. [23] Lunar occultations of Antares are fairly common, depending on the 18.6-year cycle of the lunar nodes. The last cycle ended in 2010 and the next begins in 2023.
An occultation is an event that occurs when one object is hidden from the observer by another object that passes between them. The term is often used in astronomy, but can also refer to any situation in which an object in the foreground blocks from view (occults) an object in the background.
Planetary transits and occultations. In astronomy, planetary transits and occultations occur when a planet passes in front of another object, as seen by an observer. The occulted object may be a distant star, but in rare cases it may be another planet, in which case the event is called a mutual planetary occultation or mutual planetary transit ...
Bürg (crater) / 45.0; 28.2. Bürg is a prominent lunar impact crater in the northeast part of the Moon. It lies within the lava -flooded, ruined crater formation designated Lacus Mortis. To the south and southeast is the crater pair Plana and Mason. To the west, beyond the rim of Lacus Mortis, is the prominent crater Eudoxus .

Scientists observing the occultation could get more detailed and accurate measurements of the asteroid’s size and insight into what’s happening with Betelgeuse, which suddenly dimmed in 2019 ...
A grazing lunar occultation (also lunar grazing occultation, lunar graze, or just graze) is a lunar occultation in which as the occulted star disappears and reappears intermittently on the edge of the Moon. [ 1] A team of many observers can combine grazes and reconstruct an accurate profile of the limb lunar terrain.
Radio occultation. Radio occultation analysis of signal delay by the tandem FORMOSAT-3/COSMIC used as atmospheric sounding. Radio occultation (RO) is a remote sensing technique used for measuring the physical properties of a planetary atmosphere or ring system. Satellites carrying onboard GNSS-Radio occultation instruments include CHAMP ...
