Shimmins use lunar occultations to determine a precise position for the quasar 3C273 and deduce that it is a double source, ...
Direct measure of radius (by interferometry and lunar occultation) depends strongly on color and where we are in the pulsational cycle, ...
The most frequent and readily observed type of occultation, termed a lunar occultation, occurs when the Moon passes in front of a star.
16 at the equator (Kenneth Croswell, 2005; McAlister et al, 2005); Henson, et al, 1989; and angular diameter in two colors from a Lunar occultation from Richard R. Radick, 1982), and 140 times its visual luminosity (240 times with ultraviolet).
[2] Antares B can be observed with a small telescope for a few seconds during lunar occultations while Antares itself is hidden by the Moon; it was discovered during one such occultation on April 13, 1819.
same time, optical and radio observations have vastly improved: laser retroreflectors have been placed on the lunar surface, and new radio techniques, including very long-baseline interferometry (VLBI), have been applied to observe lunar occultations ...
Regulus, lodges close to the southern limit of the Moon's travels south of the ecliptic. Stars that stand rather close to the northern or southern limit of the Moon's orbit north or south of the ecliptic have the longest series of lunar occultations.
