Solar Cycle 25 is still in max phase, so more aurora-boosting sun storms could be coming

SIGN UP ⋅   WEBSITE   The Launchpad SpaceX planning 'chopsticks' catch of Starship in early 2025 (SpaceX) SpaceX doesn't plan to rest on its rocket-catching laurels. The company made spaceflight history on Sunday (Oct. 13) during the fifth test flight of its Starship megarocket, when the vehicle's Super Heavy booster came back to its launch mount, where it was caught by the "chopstick" arms of the launch tower. SpaceX aims to do the same with Starship's 165-foot-tall (50 meters) upper-stage spacecraft - known as Starship, or simply Ship - in the coming months as well, according to company founder and CEO Elon Musk.

Solar activity waxes and wanes on an 11-year cycle. The current cycle, known as Solar Cycle 25, began in December 2019 and is still in its maximum phase, experts say.

On Thursday (Oct. 17) at 7:26 a.m. EDT (1126 GMT), the moon will officially turn full. And less than 11 hours earlier, at 8:48 p.m. EDT on Wednesday evening (0048 GMT on Oct. 17), the moon will also arrive at perigee, its closest point to Earth, at a distance of 221,938 miles (357,174 km) away. The result of these two occurrences will be a 14% brighter-than-average full moon accompanied by unusually high and low tides later this week into the start of the weekend.

Cuillandre, E. Bertin, G. Anselmi CC BY-SA 3.0 IGO) The Euclid Space Telescope has revealed the "first page" of the cosmic atlas it is building. The section of the map of the cosmos being built by Euclid was released on Monday (Oct. 15), and it features tens of millions of stars within the Milky Way and around 14 million distant galaxies beyond our own.

The mission launched from Florida's Cape Canaveral Space Force Station at 2:10 a.m. EDT (0610 GMT). As usual, the Falcon 9's first-stage booster came back to Earth safely, touching down on the drone ship "A Shortfall of Gravitas" off the Florida coast about eight minutes after launch.

Уважаемые коллеги!

На заседании Ученого совета ИТФ в пятницу 18.10 в 11:30 будет заслушан 1 доклад:
1). Сергей Тарасенко (ФТИ им. А.Ф. Иоффе)
Нелинейный отклик двумерного электронного газа на структурированное излучение

Обсуждается отклик двумерных электронных систем на структурированное электромагнитное излучение, примером которого являются векторные пучки, состоящие из когерентных волн с различной поляризацией, или закрученные пучки, несущие орбитальный угловой момент. Показано, что структурированное излучение генерирует постоянные токи и токи на удвоенной частоте, даже если двумерная система однородна и изотропна в плоскости [1,2]. В отличие от традиционных фотогальванических эффектов и эффектов генерации второй гармоники, изучаемые эффекты второго порядка обусловлены не отсутствием центра инверсии в среде, а пространственной неоднородностью самого электромагнитного поля. Возникающие токи могут быть связаны с пространственными градиентами интенсивности, поляризационных параметров Стокса или фазы электромагнитного поля. Обсуждаются микроскопические механизмы генерации нелинейных токов.
