Вчера отдал свои данные наблюдений и фильтр для проверки Угольникову. Он сказал, что затмение было ярким (всего в 300 раз изменили экспозицию в ИК в КрАО), а у меня в "В" изменение было в 10 тыс раз!!!
Вот и подтверждение слов Олега:
BRIGHT ECLIPSE: Shadows are supposed to be dark, but when Earth's shadow fell across the Moon last week the result was "rather bright," says atmospheric scientist Dr. Richard Keen of the University of Colorado. On the scale of astronomical magnitudes, "the eclipsed Moon of Feb. 20, 2008, registered -3, almost a thousand times brighter than the classic dark eclipse of Dec. 30, 1963, which followed the eruption of the Agung volcano in Indonesia."
Photographer Lorenzo Comolli sends this picture of Crater Tycho at mid-eclipse from his backyard observatory in Tradate, Italy:

The red light around Tycho is sunlight filtered and redirected by Earth's stratosphere into the core of our planet's shadow. "This eclipse was so bright because the stratosphere is exceptionally clear," explains Keen. Volcanoes can clog the stratosphere with ash and other aerosols, making lunar eclipses dark, but it has been a while since a major eruption. "The stratosphere has been clear since about 1995 after aerosols from Pinatubo's 1991 eruption settled out, and it appears to be getting more clear with each eclipse."
Keen tracks the brightness of lunar eclipses because they reveal the opacity of Earth's upper atmosphere. "A clear stratosphere means plenty of undiminished sunlight heating Earth"--something climate change models must take into account. "Lunar eclipses are not only beautiful," he says, "they can teach you a lot."
