AR 3664 на заходящем Солнце APOD: 2024 May 13 Б AR 3664 on a Setting Sun
13.05.2024

It was larger than the Earth. It was so big you could actually see it on the Sun's surface without magnification. It contained powerful and tangled magnetic fields as well as numerous dark sunspots.



AR 3664: гигантская группа солнечных пятен APOD: 2024 May 11 Б AR 3664: Giant Sunspot Group
11.05.2024

Right now, one of the largest sunspot groups in recent history is crossing the Sun. Active Region 3664 is not only big -- it's violent, throwing off clouds of particles into the Solar System. Some of these CMEs are already impacting the Earth, and others might follow.



Вспышка на солнечном пятне 875 Sunspot 875 Flares
2.05.2006

An unusually active sunspot region is now crossing the Sun. The region, numbered 875, is larger than the Earth and has produced several solar flares over the past week. It should take a few more days for Sunspot 875 to finish crossing the solar disk.



Петли солнечных пятен в ультрафиолете Sunspot Loops in Ultraviolet
8.05.2002

It was a quiet day on the Sun. The above image shows, however, that even during off days the Sun's surface is a busy place. Shown in ultraviolet light, the relatively cool dark regions have temperatures of thousands of degrees Celsius.

Приближение Союза к Космической станции A Soyuz Spacecraft Approaches the Space Station
1.11.2005

Last month, a Soyuz TMA-7 spacecraft docked with the International Space Station. The spacecraft was launched a few days earlier from the Baikonur Cosmodrome in Kazakhstan. Pictured above, the approaching Soyuz spacecraft carried the new Expedition 12 crew to the Earth-orbiting International Space Station (ISS), as well as fee-paying spaceflight participant.



Прощай,  AR 10486 Flare Well AR 10486
6.11.2003

Almost out of view from our fair planet, rotating around the Sun's western edge, giant sunspot region AR 10486 lashed out with another intense solar flare followed by a large coronal mass ejection (CME) on Tuesday, November 4th at about 1950 Universal Time.



Солнечные пятна и активные области Sunspots and Solar Active Regions
1.08.2002

July was a good month for sunspots ... really big sunspots. In fact, the full disk and inset pictures above show three large groups of spots, photographed only a few days ago on July 28. Together the sunspots span a region about thirty times the diameter of planet Earth.



Группа солнечных пятен номер 30 Sunspot Region 30
18.07.2002

The solar active region designated number 0030 is now appearing on the visible hemisphere of the closest star. Dwarfed by the Sun's disk, the group of sunspots which make up region 30 actually cover an enormous area -- nearly 10 times the size of Earth.



Огромная активная область пересекает Солнце A Large Active Region Crosses the Sun
26.07.2004

An unexpectedly large sunspot region is now crossing the Sun. The active region is home to rivers of hot plasma, explosive flares, strong magnetic fields, a powerful Coronal Mass Ejection (CME), and a sunspot group so large it can be seen by the protected eye without magnification.
