SOLAR CYCLE 25 ACTIVITY REPORT JANUARY 06_2023

Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C3 event observed at 0809 UTC from Region 3534 (S15W61).

There are currently 8 sunspot regions on the solar disk: AR3534, AR3536, AR3537, AR3538 and new regions AR3539, AR3540, AR3541, AR3542​

Total number of sunspots has increased to 121 (41 of these are grouped into 8 active regions) NOAA forecasts for the next 24h: 95% chance for C flares, 35% chance M flares and 10% chance for X flares.

AR3536 continues with delta-class magnetic field that poses a threat for strong X-class solar flares while the remaining regions have a stable magnetic field.​

SOLAR MAX IS COMING: Since Solar Cycle 25 began in Dec. 2019, 782 sunspot groups have crossed the face of the sun. Almost half (361) appeared in 2023. This montage assembled by Ali Ebrahimi Seraji of the Mahani Observatory in Iran shows how sunspot production has skyrocketed:​

​

"I created this 4-year overview using images from NASA's Solar Dynamics Observatory," says Seraji. "The graph beneath the images is from NOAA; it shows actual monthly sunspot counts (white) vs. predictions (blue). The sun is outperforming the forecast."​

Many forecasters believe that Solar Max will occur in 2024. That means we can expect *even more* sunspots this year. Solar flare, geomagnetic storms and auroras are in the offing.​

THESE AURORAS ARE NOT AURORAS: On Jan. 5th, two seemingly unrelated things happened in Stockholm, Sweden: A punishing cold wave hit the city, plunging the air temperature almost 30 degrees below freezing. At the same time, aurora-colored lights filled the sky. Yet these were not auroras:​

​

"With the extreme cold, ice crystals filled the air," says photographer Peter Rosén in downtown Stockholm. "This created a magnificent display of light pillars that looked almost like Northern Lights."​

Light pillars are manmade lights spread into colorful columns by large wobbly snowflakes and other crystals. No solar activity is required. The only ingredients are ice and light pollution.​

The red lights in Rosén's photo are aircraft warning beacons on tall buildings and construction cranes. Other colors correspond to high pressure sodium lamps (warm orange) and modern LED lamps (blue-white). SpaceWeather.com​

THE POLAR VORTEX WOBBLED IN DECEMBER: Last month, sky watchers in Europe saw something rare and beautiful. A giant bank of polar stratospheric clouds (PSCs) escaped the Arctic Circle, and for more than a week they filled skies with rainbow color as far south as Italy. In the Italian commune of Sanfrè (latitude +45N), Pablo Javier Lucero was able to photograph the clouds at all hours of the day:​

​

"Utterly incredible!" says Lucero. "I first saw the clouds at sunset on Dec. 22nd. After talking with a friend of mine, Jorgelina Alvarez, a meteorologist, we realized that these clouds weren't ordinary iridescent clouds, but rather Type II polar stratospheric clouds. My surprise was gigantic."

Surprise is the correct reaction. Normally, Earth's stratosphere has no clouds at all. Only when the temperature drops to a staggeringly-low -85 C can widely-spaced water molecules assemble into icy polar stratospheric clouds. With colors that rival auroras, PSCs are considered to be the most beautiful clouds on Earth.

During the outbreak, Spaceweather.com received hundreds of photos of PSCs. Curiously, they all came from Europe. 100%. No photos were received from North America or Asia. Why not?

Amy Butler of NOAA's Chemical Sciences Laboratory has the answer: "The polar vortex can wobble like a top, and in December it was displaced towards Europe," she explains. "You can see this in the figure, below, from Zac Lawrence's website stratobserve.com."​

​

Cold air normally contained over the poles was carried by the wobbling vortex to mid-latitudes. Purple and green contours in the figure show where temperatures were cold enough for Type I and Type II PSCs, respectively.

Since the December outbreak of PSCs, which ended around Christmas, the polar stratosphere has warmed more than 10 degrees. Butler says this is probably the result of "a strong planetary wave breaking in the stratosphere." Wave energy warmed the air and dispersed the rainbow-colored clouds.

It could happen again, though; there's plenty of winter ahead. As January unfolds, the polar stratospheric vortex is still tilted toward the mid-latitudes of Europe. If the stratosphere cools, PSCs could re-appear over populated areas. You can monitor the situation with daily temperature reports. SpaceWeather.com​

There are currently 9 sunspot regions on the solar disk: AR3536, AR3537, AR3538 AR3539, AR3540, AR3541, AR3542, AR3543, AR3544

denvergazette.com

Jan 10, 2024 Updated 5 hrs ago.


In the weather world, there's a term you probably haven't heard before – 'WeatherGami,' and it deals with how often a specific high temperature of the day is matched with a specific low temperature of the day. It's perhaps best described by the graph shown at the top of this article, which depicts a series of dots placed on the graph considering daily minimum and daily maximum temperatures of each date.

Data goes back to 1872, with the frequency of max/min temperature occurrences are carefully tracked over the past 152 years.

While a high of 84 degrees and a low of 56 degrees has been recorded 92 times over that century-and-a-half-plus period, the unique combination of yesterday's high of 43 degrees and low of -2 degrees in the area of Denver International Airport has never been recorded before, according to the National Weather Service.

That's pretty wild considering that the graph depicting all daily temperature recordings between 1872 and 2024 would contain around 55,000 data points.

So, congrats, Denverites! Even though you probably didn't even notice at the time, you have officially experienced a one-of-a-kind weather day in the Mile High City.

SO MANY MAGNETIC FILAMENTS: Today there are a dozen sunspot groups crossing the face of the sun. This spectroheliograph image reveals an even greater number of magnetic filaments:​

Francois Rouviere captured the image from Cannes, France. It shows the sun in the monochromatic wavelength of red light emitted by solar hydrogen. Each irregular dark line is a magnetic tube filled with dense hydrogen gas. These filaments are just as likely to erupt as the sunspots, more than doubling the chances of a flare today.

SOLAR CYCLE ACTIVITY REPORT JANUARY 15_2024

ALL QUIET. Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C9 event observed at 12:06 UTC from a unnumbered region

https://twitter.com/x/status/1746735531289919707

There are currently 12 sunspot regions on the solar disk: AR3540, AR3541, AR3544, AR3545 AR3546, AR3547, AR3548, AR3549, AR3550, AR3551, AR3552, AR3553​

AR3539 is gone

Total number of sunspots has decreased to 183 (61 of these are grouped into 12 active regions) NOAA forecasts for the next 24h: 95% chance for C flares, 30% chance M flares and 5% chance for X flares.

Sunspot AR3541 formed a weak delta configuration that poses a threat for Earth-directed M-class solar flares.​

A CME IS ABOUT TO HIT MERCURY *AND* VENUS: A spectacular CME left the sun on Jan. 14th. It won't hit Earth. Instead, Mercury and Venus are in the line of fire. This NASA model shows it striking the two planets in quick succession:

​

The strike on Mercury (Jan. 15th) could ignite X-ray auroras on that planet's rocky surface, while the strike on Venus (Jan. 16th) will probably erode a small amount of its upper atmosphere. Earth isn't the only world with space weather! Aurora alerts: SMS Text
