Catalogue of double stars . The Pulkovo Visual Double Star Catalogue Based on the Relative Positions Derived from the Photographic Observations Made with 26-inch Refractor since 1960. ... Into the present catalogue the seasonal mean relative positions ( r and q 2000 ) are included for 234 visual double stars observed at Pulkovo with 26-inch refractor from 1960 through 2001. ... The photographic and CCD observations of visual double stars are being continued now. ... The Format of the Catalogue. ...

... ПЕРВЫЕ СНИМКИ LROC . Один из первых снимков поверхности Луны с полным разрешением, камера NAC. ... Камера LROC WAC представляет собой совсем другой тип системы съемки, чем NAC. ... Полученный камерой WAC обзор области Deslandres значительно перекрывает снимок от камеры NAC, это объясняется тем, что поле обзора камеры WAC в 20 раз шире чем у камеры NAC, но при этом ее разрешение значительно ниже. ... Граница изображения NAC показана в виде двух вертикальных полос на этом обзоре камеры WAC. ...

Анимация трех первых снимков за 12:24-12:28 UT 22 октября: http://master.sai.msu.ru/static/NEO/MASDA1-Tunka-anim.gif. В момент открытия в Тунке 22 октября астероид находился на расстоянии 0.043 а.е. (6.5 млн км) от Земли. На минимальном в этом году расстоянии 0.0115 а.е. прошел 17 октября, за 5 суток до открытия. ...

... Norm Oberle being reflected by one of his . ... The 31" mirror at the . ... It was through Norm's classes that I made my own two telescope mirrors described elsewhere on this site. ... Soon he made his first first telescope. ... Norm was one of the charter members and organizers of Cuyahoga Astronomy Club and its first president. ... In 1968, Norm formed the LEAP Project (Lake Erie Astronomical Project) partially an out growth of the telescope making class and astronomy meetings at the planetarium. ...

... The AAAP had a busy booth at this year's Super Science Weekend, hosted by the New Jersey State Museum in Trenton. ... AAAP astronomers received a steady stream of curious "customers" who looked at our nearest star, and were wowed by photos, magazines and other astronomy information on the table. ... To get you in the contemplative mood, I've added one of Bill Murray's first astro images produced at his new home observatory. ... The next new moon Friday is June 6th which is too soon to plan. ...

... Today this year's largest group of sunspots will cross the Sun's central meridian. ... The next day, the number of spots in the group reached five, and the day after, on June 2nd, it was possible to count thirteen sunspots on solar disk, which had been clear prior to this. ... This year's two most powerful active areas, which passed across the solar disk at the beginning of May, 2009, are set to appear in the Sun's eastern sector in two days, on June 6th. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...
