Unedited Solar Images from Jan 2012 onwards

[superiorstream]

Hi,Alfred
Nice photos from you.Thanks for sharing.
Here are the photos--to be uploaded by Gary later--of 1589 in Cak.Its not surprising that it didn't show up quite as clearly in Ha(even double stacked to bandwidth 0.5A) as in Cak.Remember the curve on 'black body radiation' and the associated curve with the spectra line superimposed.As the temperature increases,the whole curve shifts(an exponential curve basically) upward and the upward shift--indicating intensity increase--is highest in the short wavelength side.Thus for a given increase in temperature,more mark increase in intensity in the short wavelength--now Cak vs Ha--occur.Also this confirm that what we are seeing is a region of higher temperature around the sunspot.
Also do observe that the shape of the region do changes--even daily--indicating the great amount of activities around the sunspot.
Anyway for those who are not interested in those physics talk,do enjoy the photos.Thanks.
Hi,Gary
Thanks for the upload beforehand.

Hi Mr Chia,

Thanks for the Physics It is all coming back slowly. Used to work on thermal imagers in 3-5 um and 8-12 um range

Will be looking out for the CAK images on 1589.

I have always been amazed by the details provided by CAK solar scopes. Hope to get one in the near future when funds are available. For those who are interested, here is an article on CAK - will make enjoying the CAK images provided by Mr Chia more meaningful. http://solarastronomy.org/Observing%20i ... II%20K.pdf

Enjoy!

Hi,Gary
Again thanks for the upload,esp at that hour!

M-class flare! Enjoy!

Hi,All
These 2 photos shows sunspot 1611(8 nov 2012) in flare.I watch it throughout for about 20 minutes.The area affected was about 3 to 4 earth diameter.I saw the
surface--edge on---of the sun CHANGING SHAPE!Sometimes it change into the shape of a glowing volcano mouth;sometimes into a glowing
mountain ridge.First time in my life see such hugh change took place in just 20 min!Fantastic view of a lifetime.Anyway within 3 days of this event,
Quatimalia(Sound like that) and Burma experiences earthquake.Also noted irregular BLACK ants activities before that--coincidences?
Also note that recently the sun exhibit 'sudden burst of activities' more and more often.That makes it more worthwhile to watch daily and who knows
what we will capture next!!
Thank Gary for uploading.

Hi,All
At last--one article in spaceweather.com on how solar activities affects our weather--quote-"there are signs of enhanced precipitation in the Pacific ITCZ (Inter-Tropical Convergence Zone ) and SPCZ (South Pacific Convergence Zone) as well as above-normal sea-level pressure in the mid-latitude North and South Pacific," correlated with peaks ...........".Yes a pattern.Also note whats mention in the article of increase in UV radiation on the weather.That UV enhanced radiater
can be seen in CAK photos as BRIGHT patches.Well,I observe a correlation between heavy superstorm downpour and 'the active band across the sun--in Cak' years ago and WAS considered talking nonsence.Now experts are seeing pattern in it too.Turn to spaceweather.com>>change date to 8 Jan 2013---and you will find that interesting article.Anyway the bands--now one in the north and one in the south ---are showing again.In actual fact;I do continue to observe a correlation too--esp when those recent superstorm hits China ,Japan,etc recently---after that incident-- but didnt pass my comment here after that.Will be posting such Cak photos if weather allows photo-ing.Thanks.

Hi Mr Chia,

thanks your sharing and hope to see your photos of the sun if the weather permits.

Managed to find the article you were talking about.
hope this the correct article.

Hi,Davegn
Yes the first article is the one I am refering to--sorry I am a zero in IT.Thanks for your help.In fact due to my almost daily observing of the
sun and those long period--Since the early 80's--its almost obvious to me ,then, that our weather is related to solar activities(as far back as 2004,a
hugh sunspots region suddenly appear covering like 1/4 to 1/5 of the side facing us and thereafter it rained--by coincidence say--rained for 5 to 7 days in heavy burst)
and more related to those UV active/bright regions.1 to 1 correspondence although not achieved,but some 2 to 5 days
delays observed sometimes---and thats what keep my passion burning ;although observing the sun turn me into a 'carbon rod!'Will definitely share
those beautiful photos of the banded Cak Sun.Thanks.

The cited articles are rather circumspect in their claims, and I have extracted some below as examples. There is a current lack of sufficient understanding and proof of any correlation between solar activity and regional / global climate, not to mention local weather events. While it is good to keep an open mind, one must guard against being gullible or falling into common pitfalls to good science, such as confirmation bias.

For example, one may choose to believe that because they see periods of rain (or earthquake) in their neighbourhood after observing heightened sun spot activity, there is therefore a high likelihood of correlation between the two. But heh, what about other instances when such events do not happen? A person suffering from confirmation bias will tend to ignore such events. And what about an observer a 100km away, who may not even see a drop of rain? So can you attribute the rain or lack of rain to solar activity? And there are a host of other possible reason for the rain, e.g., the monsoon season.

Some extracts
"Much has been made of the probable connection between the Maunder Minimum, a 70-year deficit of sunspots in the late 17th-early 18th century, and the coldest part of the Little Ice Age, during which Europe and North America were subjected to bitterly cold winters. The mechanism for that regional cooling could have been a drop in the sun’s EUV output; this is, however, speculative."

"Hal Maring, a climate scientist at NASA headquarters who has studied the report, notes that “lots of interesting possibilities were suggested by the panelists. However, few, if any, have been quantified to the point that we can definitively assess their impact on climate.” Hardening the possibilities into concrete, physically-complete models is a key challenge for the researchers.
