Затишье перед бурей?

QUIET SUN: The face of the sun is peppered with spots, but none of them is actively producing flares. Since yesterday, the sun's X-ray output has flatlined:

Despite the quiet, there is potential for Earth-directed eruptions. Sunspots 1362 and 1363 have "beta-gamma" magnetic fields that harbor energy for M-class solar flares. NOAA forecasters estimate a 20% chance of M-flares during the next 24 hours. Solar flare alerts: text, phone.

SUBSIDING SUNSPOT: After three days of meteoric growth, sunspot AR1363 has reversed course and is beginning to decay. As its magnetic field relaxes, the active region poses a subsiding threat for strong flares. It's not dead yet, though, as this snapshot shows:

NASA's Solar Dynamics Observatory recorded this extreme ultraviolet flash from a C6-class solar flare in the sunspot's magnetic canopy during the late hours of Dec. 5th. AR1363 is crackling with low-level flares like this one.

There is still a slim chance that AR1363 will buck the trend and unleash a major M- or X-class eruption. If such an flare happens today, it will be geoeffective because the sunspot is facing Earth. Quiet, however, is more likely. Solar flare alerts: text, phone.

Похоже что "просто затишье", к примеру предыдущая огромная группа 1139 так и не выдала ничего серьезного.

шо за люди? никак им не угодить ... много сильных вспышек, начинают истерить что "все песец, мы все умрем" ... нету вспышек, сразу начинают истерить про "затишье перед бурей" ...

Напомним,что: Со 2 декабря площадь группы 1363 увеличилась в три раза и обрела более сложную магнитную конфигурацию. Ее энергетический потенциал способен на вспышки Х-класса.

GROWING THREAT OF FLARES: What a difference a weekend makes. Since Friday, sunspot AR1363 has nearly tripled in area and it has developed a delta-class magnetic field that harbors energy for X-class solar flares. This 48-hour movie from NASA's Solar Dynamic Observatory shows the changes on Dec. 3-4:

Despite its growing potential for explosions, the sunspot remains mostly quiet producing no flares stronger than C-class. Is this the quiet before the storm--or just plain quiet? Stay tuned. Solar flare alerts: text, phone.
