New observations show that the lightcurve of Kuiper belt contact binary (139775) 2001 QG298 has changed substantially since the first observations in 2003. The 2010 lightcurve has a peak-to-peak photo...
利用上海天文台多星定轨的软件（ＣＯＭＰＡＳＳ），对１９９８年１月 ～２００１年１２月期间的 Ｌａｇｅｏｓ１、Ｌａｇｅｏｓ２卫星的激光测距资料重新归算了地球定向参数ＥＯＰ（ＣＯＭＰＡＳＳ），并将结果与同期的ＥＯＰ（ＩＥＲＳ）Ｃ０４进行了比较，得到其外符精度为：极移ＸＰ—０．３２ｍａｓ，ＹＰ—０．３４ｍａｓ，日长变化 Ｄｒ—０．０２５ｍｓ。

A peculiar nova-like MV Lyr was investigated. The CCDobservations
ofMVLyr were continued in Crimea during the outbursts and
quiescent states. Last year its behavior became non-typical for “anti-dwar...
