... What is the notion time? ... Generally speaking, it is an order of changing events, an order of constantly changing conditions of solids, Universe - being. ... The time, determined for the given longitude, is called the local time . ... A uniform system of time counting - ephemeris time is tested by observations of the Moon turning around the Earth. Fully independent from astronomic observation uniform system of the time counting is based on the concept of atomic second (see quantum watches ). ...

. Three times Disappointed. Такой прекрасной не увидеть, . Такой чудесной не найти, . Никто не сможет так обидеть, . Никто не сможет не прийти. Нигде ведь нет такой улыбки . И миллиона слов пустых. И более дурной ошибки . Уж нет... Но вижу вас двоих... Я без тебя не вижу смысла . Мне жить, учиться и страдать, . И сердце в горести так сильно... Увы! Тебя мне не понять... Твое внимание прекрасно, . Твои слова так сладки мне, . Но полюбить тебя - опасно - . Гореть на жертвенном огне. 10.05.2001

Nova 1998 2 in M31 this image of the second Nova in M31 in 1998, was made from 38 exposures of 45 seconds integration time. It was made at September 21, 22h 20m UT. Telescope was a CG11 at f/6.3, no filters were used. The long list of processing steps caused the artefacts at the overexposed center of the galaxy and in many of the brighter stars. During the exposures thin clouds covered the sky but the CCD cuts through them, allowing me to obtain this result. ...
