Sol (Sun) and its phenomena

SOLAR CYCLE 25 ACTIVITY REPORT DECEMBER 17

What a crazy couple of days! After what feels like months of relative silence our Star woke up. We had 29 solar flares that reached the M-class threshold over 72 hours period. Did any of these solar flares produce any significant coronal mass ejections? We have to wait a little and see.

Thus, solar activity remains at a high level. These were the M-class solar flares of the past 24 hours

● M3.5 at 02:05 UTC on Dec/16 from AR3165 it produced a Minor R1 Radio blackout over Oceania
● M1.2 at 05:05 UTC on Dec/16 from AR3163 it produced a Minor R1 Radio blackout over Indian Ocean
● M1.3 at 05:56 UTC on Dec/16 from AR3165 it produced a Minor R1 Radio blackout over Indian Ocean
● M1.2 at 06:56 UTC on Dec/16 from AR3165 it produced a Minor R1 Radio blackout over Indian Ocean
● M1.6 at 07:45 UTC on Dec/16 from AR3165 it produced a Minor R1 Radio blackout over Indian Ocean
● M1.5 at 09:15 UTC on Dec/16 from AR3165 it produced a Minor R1 Radio blackout over Indian Ocean
● M1.1 at 09:55 UTC on Dec/16 from AR3165 it produced a Minor R1 Radio blackout over Indian Ocean and Africa
M4.0 at 10:26 UTC on Dec/16 from AR3165 it produced a Minor R1 Radio blackout over Indian Ocean and Africa
● M2.4 at 14:45 UTC on Dec/16 from AR3165 it produced a Minor R1 Radio blackout over Africa
● M1.2 at 15:46 UTC on Dec/16 from AR3165 it produced a Minor R1 Radio blackout over Africa
THE EXPLOSIONS CONTINUE: Sunspot AR3165 is crackling with M-class solar flares, more than 18 in the last two days. Pulses of extreme ultraviolet radiation are ionizing the top of Earth's atmosphere, causing frequent shortwave radio blackouts. The blackout events are regional, like this one, but they are rolling around the globe as Earth turns beneath the flaring sun.

The constant flaring of AR3165 has made it easy for astrophotographers to catch the sunspot exploding. Sylvain Weiller sends this picture of today's M4-class flare from Jerusalem:​

A MORE DANGEROUS SUNSPOT: Sunspot AR3165 may be crackling with solar flares, but it is not directly facing Earth. Most of the debris from those explosions is completely missing our planet. Meanwhile, there is a more dangerous sunspot. AR3163 has an unstable magnetic field and it is staring straight at us:
latest_4096_HMIIF_strip4.jpg
A magnetic map of the sunspot (inset) shows a mixture of polarities in the region between the sunspot's primary cores. Plus (+) is bumping into minus (-). This could cause explosive magnetic reconnection and a powerful Earth-directed solar flare. Any CME emerging from the blast site would almost certainly strike our planet, causing geomagnetic storms.

So far AR3163 is quiet despite its potential, but it will be facing Earth for several more days. Tick, tock, dangerous sunspot. SpaceWeather.com​

SOLAR CYCLE 25 ACTIVITY REPORT DECEMBER 20

Solar activity has been at low levels for the past 24 hours. Several minor C-class flares. The largest solar event of the period was a C8 event observed at 14:29 UTC from Region 3169 located on the northeast (N21E48).

There are currently 8 numbered sunspot regions on the solar disk: AR3162, AR3163, AR3166, AR3167, AR3168, AR3169 AR3170 and new region AR3171

AR3171 located on the northeast (N25E65) is a group of 5 sunspots. The region has an area of 30 millionths of a hemisphere and the sunspots have a beta magnetic field. (bipolar) According to NOAA the region has a 20% chance of producing C-class flares.

We will see how AR3171 behaves in the coming days. Perhaps it will happen like the previous regions that in the eastern limb appear very fierce but then calm down in their transit to the west to once again become threatening.

AR3169 located in the northeast (N21E45) next to the region AR3171 is growing and could soon pose a threat for significant solar flares according to SpaceWeather. Currently this region is 300HM in size and is composed of 11 sunspots with a beta magnetic field. According to NOAA it has a 70% chance of producing C-class flares and a 15% chance of producing M-class flares.

SOLAR CYCLE 25 ACTIVITY REPORT DECEMBER 24

Solar activity has been at low levels for the past 24 hours. Several minor C-class flares were recorded. The largest solar event of the period was a C6.6 event observed at 14:46 UTC on December 23 from Region 3171 located on the northeast (N25E13).

A: Probably will call it a giant comet or the flaring of same.
The following "official" version reminded me of the answer from the Cs. This object is not Nemesis, however, it is an example that "they" can name what appears up there however they want to.

And unusual object in the SOHO/LASCO field of view.

On December 20, 2022, Sungrazer Project citizen scientist Zesheng Yang reported coordinates of an unusual object in the LASCO C2 and C3 fields of view. Having seen and discovered many comets in the SOHO data, Zesheng knew immediately that this was something different, as did we. In fact, in 27 years of operations SOHO has never quite seen something like this, despite having seen it many, many times...

The LASCO C3 view on 2022-12-20 from 06:18 through 08:30UT.
c2_debris_2022.gif
The LASCO C3 view on 2022-12-20 from 06:18 through 08:30UT

What is most notable here, as pointed out by many, is the way in which it seemingly rapidly turns away from the Sun. SOHO has seen literally thousands of comets, some of which do indeed follow a curved trajectory, but not over such short timescales and with such a dramatic curve. So naturally this led to an influx of questions from curious SOHO fans. Fortunately here we have several pieces of evidence that point to a clear (albeit somewhat unexciting) answer: it's just a piece of dust.
( years of experience and the scientist Zesheng does not know how to recognize a speck of dust?)

Here's how we know this:
  • SOHO quite routinely sees what we call "debris" images. Here is a pretty dramatic example from 2020 in which we see multiple dust streaks across the image. This is caused by tiny micrometeorites hitting some part of the spacecraft and throwing up a puff of debris. (Note that the image presented as proof is static).
  • The curvature of the object's trajectory tells us that it cannot be close to the Sun -- the laws of physics simply would not support that at all because of how far away it would have to be and how bright it is (more on this below). So it must be close to the spacecraft.
  • So now we will address the question that everyone is thinking: why couldn't this be a spacecraft (or Santa test driving a new sleigh, which is our preferred alternate reality)? Well, if it was near the Sun, it would have to be truly vast in size to reflect as brightly as it does - like planet-sized - and something like that making its way into the solar system is going to get noticed and reported by a global army of amateur astronomers long before SOHO spots it! And to change trajectory
So putting all this together, the physics and optical signature of the feature point almost unambiguously to this being something very small, and very close to the spacecraft (probably within a dozen feet or so). We also have clear evidence that immediately before it appeared, a micrometeorite created a small cloud of debris around the spacecraft, which is an event that happens at least several times per year. This adds up quite conclusively to a very fortuitous observation of a dust speck that by chance stayed perfectly in front of the LASCO C2 and C3 optics for a couple of hours
NASA Conclusion: Must be Santa

SOLAR CYCLE 25 ACTIVITY REPORT DECEMBER 28

Solar activity has been at moderate levels for the past 24 hours. Several minor C-class flares and two M-class flares were recorded.

A M1.0 from AR3176, located on the northeast, ocurred at 08:15 UTC on December 27 it produced a Minor R1 Radio blackout over Indian Ocean.

A M1.2 from AR3169 located on the northwest ocurred at 16:26 on December 27, it produced a Minor R1 Radio blackout over South America

Many of us have noticed for example, that, lately, regions with potentially dangerous sunspots for producing M-class and X-flares do not do so once they are facing the Earth,
The M-class flares of the past 24 hours are an example of the above. AR3176 made its presentation in the northeast with a M2.07 on December 27 while AR3169 is saying goodbye with an M1.2.

AR3169 appeared in the solar disk on December 17 and did so with an M1.09 flare, then an M1.1 flare, during its westward path, generated only C-class flares.

Let's see how AR3176 behaves on its way west.

There are currently 6 numbered sunspot regions on the solar disk: AR3169, AR3171, AR3172, AR3173, AR3175 and AR3176

The total number of sunspots has decreased to 89 (41 of these are grouped into 7 active regions) NOAA forecasts for the next 24h: 99% chance for C flares, 55% chance for M flares and 15% chance for X flares.

CHANCE OF FLARES TODAY: NOAA forecasters say there is a 55% chance of M-class solar flares and a 15% chance of X-flares today. Sunspots AR3169 and AR3176 both pose a threat for such explosions. Neither is directly facing Earth, but they're close enough for radio blackouts and glancing-blow CMEs SpaceWeather.com
