Signs in the sun! Solar Minimum is here?

Recommended Posts

In conjunction with the  AR2734  sunspot that has its plages aligned North-South rather than the more typical East-West alignment, the sun in the last hour produced a very interesting phenomenon observed in the HMI Colorized Magnetogram (see image attached).  The magnetic-field flux tubes coursing underneath the photosphere 'surface' briefly became 'densified', as if a surface 'flush' occurred, resulting in the finely-speckled green/yellow pattern in the HMI Magnetogram.  Maybe these are signs of the bottoming-out of SC24 minimum, and the sun is now transitioning into SC25 going forward. 😃

Conversely, maybe the speckled pattern instead has something to do with an adjustment in the instrument. 😁

I do not know what exactly caused this artifact but I am sure it is some sort of faulty reading from the HMI instrument. It has nothing to do with anything that occurred on the Sun that is for sure. You can see a similar fault at 01:15 UTC as well on just a small part of the Sun.

Due to the lack of sunspots and the effect on our weather being much cooler , when will the globalwarming Theory be debunked , will it be to late due to crop loss and thousands dead before the truth comes forth so many can prepare for the cold weather and survive?

Marcel de Bont, Yes, I am >97% in agreement with you.  I had never seen that phenomenon in the SDO imagery before; it very well could be attributable to more of a software issue rather than a physical adjustment in the sensor electronics.  Admittedly, my original post was somewhat of a tongue-in-cheek reflection, since sometimes image artifacts are blown out of proportion on various social media channels.  Since this channel has a high-level scientific bent, I considered deleting my post altogether, but maybe it has engendered a jumping-off point for additional topics, like that presented by T. Sweany.

T. Sweany, if you carefully observe the Total Solar Irradiance, you very well may conclude, backed by a large body of scientific research, that dramatic changes in temperature and climatic response on earth has practically nothing, relatively speaking, to do with the sun, since the sun is still behaving quite consistently and normal, similar to its behavior for the past several hundred years.  If you can agree with that conclusion, then you'll need to look for the changes occurring here on planet earth, and in its atmosphere, to explain earth's weather/climatic changes.

However, T. Sweany, it is understood that studying solar physics and the weather is probably not your chosen profession, and that you may have been subjected to a lot of misinformation, such as the idea that earth has now entered into a Grand Solar Minimum.  In order for you to understand that is not the case, I recommend you direct your attention to the measurement of the Total Solar Irradiance (TSI).

Theartist: No need for the ad hominem, please.  Respectfully, to some, it reduces the value of your comment.  On the bright side, it's why I picked this sunny day here in Maryland to bite on your comment :)  If you look at ir absorption bands of co2, ch4, and h2o and relative atmospheric composition in a convective atmosphere (h2o!), milankovich cycles (obliquity!), co2 ppms and temperature data from antarctica and greenland over 100ks years (which leads which?  what are the ppms of co2 in greenland cores?), other energetic events during solar maximum (solar flares, CMEs), the difference in percentage of UV contributing to TSI between solar max and min, solar activity over the last 11k years (1900s!), I think you'll have a bigger picture.

Tony Sweany: For some, my guess is well after fingers freeze to the keyboards of some in the northern hemisphere who are banging out articles about global warming.  For others, if the next solar maximum is less than the prior one which was the lowest in more than 125 years based only on the number of sunspots, and the earth starts to cool or warm less quickly based on UAH, RSS, or future satellite data while co2 increases, to me and others, that will be the nail in the coffin of the Theory.

 

But even if the Theory is right, a warmer world, on net, is a wetter one and crops do better with more co2.  Paleo records show life flourishes during warmer periods... after all, we're in an ice age right now!

RationalArguement,  you state "Theartist: No need for the ad hominem, please.  Respectfully, to some, it reduces the value of your comment. "  

Can you please respectfully tell me what you are referring to, for I meant no "ad hominem"?  There has definitely been put out there a lot of misinformation stating earth is already in a 'Grand Solar Minimum', which is simply not the case.  Furthermore, T. Sweaney was implying there is going to be lack of sunspots directly associated with crop-losses.  So with those statements, I just presumed T. Sweaney was following the social media crowd parroting misinformation, rather than offering a professional opinion.  

BTW, I have not taken a position that recent earth weather and climate changes are due to CO2; there are other factors, some due to anthropogenic activity besides CO2 emissions, that could factor into the equation. My point was simply that it is a stretch to blame the sun, since the Total Solar Irradiance (measured at top-of-atmosphere) has only changed by 0.096% since the Maunder Minimum.
