An Electron rocket is scheduled to lift off from Rocket Lab's New Zealand site today, during a 75-minute window that opens at 9:00 a.m. EDT (1400 GMT; 3:00 a.m. on Dec. 21 local New Zealand time). Rocket Lab will webcast the action live, beginning 20 minutes before liftoff. Space.com will air the stream if, as expected, the company makes it available. Full Story: Space (12/19)  Space Quiz!

(U.S. Space Force) The U.S. Space Force celebrates its fifth anniversary today. The service was formally established on Dec. 20, 2019, when President Donald Trump signed it into law with the National Defense Authorization Act, the bill that allocates U.S. military spending each year. Since then, the U.S. Space Force has grown to nearly 15,000 servicemembers and civilian personnel. In its fifth year, Space Force has overseen astronaut launches from its facility at Florida's Cape Canaveral Space Force Station and has even seen one of its own active Guardians, as Space Force members are known, launch into space. Full Story: Space (12/20)  Skywatching How to see the Ursid meteor shower peaks this weekend (Jean Clark) Missed the Geminid meteor shower earlier this month? Don't worry. We're in for a little pre-Christmas stargazing treat. The Ursid meteor shower - the final one of the year - is predicted to peak in the early morning hours of Sunday (Dec. 22). As far as meteor showers go, the Ursids aren't known to be particularly active. If viewing conditions are perfect, you might see upwards of 10 meteors per hour, according to In-the-Sky.org. But this year, the last quarter moon will interfere with the show, so it's best to keep expectations low -- say, maybe five meteors per hour.

If you glance at NGC 2264, you'll see very quickly why this cluster of stars is nicknamed the "Christmas Tree Cluster."

Уважаемые коллеги!

На заседании Ученого совета ИТФ в пятницу 20.12 в 11:30 будет заслушан
доклад:

Леон Огородников
$\alpha$-эффект в трехмерном вихре вращающейся проводящей жидкости

Исследуется одноточечная статистика спиральных
турбулентных пульсаций в трехмерном крупномасштабном геострофическом
вихре
вращающейся жидкости. Предполагается, что спиральное течение создается с
помощью статистически аксиально-симметричной случайной силы с нарушением
зеркальной симметрии. Проводятся аналитические вычисления парных
корреляторов компонент скорости и завихренности, на основе которых
вычисляется средняя спиральность течения. Для проводящей жидкости
аналитически вычисляется $\alpha-$эффект в данной системе. Элементы
$\alpha-$тензора существенно зависят от соотношений между числами Россби
$\mathrm{Ro}$, Экмана $\mathrm{Ek}$ и магнитным числом Прандтля
$\mathrm{Pr}_\mathrm{m}$. Также в терминах данных чисел устанавливается
критерий, показывающий, когда $\alpha-$эффект приводит к неустойчивости
крупномасштабного среднего магнитного поля.
