Sun Spot AR2529 travels across the sun

I took shots over 10+ days of the sun spot traveling across the sun - tried to shoot about the same time each morning - the gap in the lower left part of the trail was the 2 days that we had clouds - today on TV they were showing the big eruption that happened on Sunday - got the spot but not the big bang - this was a fun exercise - and just done with my EOS 1d Mk IV + 400mm + 2x extender - f/22, shutter 1/200 , Iso 200 -

Very good ! You did good on the composites and you did right by shooting approx. the same time each day . Congratulations !

Great stuff! Very well done.

Hello!!

I took this on Sunday the 17th in Central Kentucky sometime around mid-late afternoon. How come there's a difference in the location of the spot?

This was with a 5D3, 400L, 2x, Big Stopper + Little Stopper

Did you perhaps rotate yours correctly and the OP did not or perhaps vice-versa ?

this is the way mine appeared as I shot them - the one I shot in the after noon was in a different location - it had rotated to the right and above

That is understandable , but if you check with www.spaceweather.com the sun as see correct is in the top left corner and you can click it for a larger image . What you do is on the right side of the webpage is the archives setting . Change it to show any of the days you imaged and check out the sun and see where the sunspot is actually located . Then rotate or flip your images to match what is shown on spaceweathers website . They always show the picture of the sun for that day and how it is oriented . Very easy process . On yours you just need to flip from top to bottom and you will be correct . Always remember the cameras image is usually up-side-down or left -to-right .

When I took these it was usually around 7:40-8:10 am in Mesa Az - I was shooting due East and the live view that I saw was how it looked- starting in the lower left and and moving toward the upper right over the 10 days- one time I waited to shoot in late afternoon 4:30 pm and the spot was now in the upper right quadrant when it had been in the lower left quadrant in the morning - I was not sure if the movement of the earth or the movement of the Sun caused this - I am not an astronomer so I was not sure why - and I looked at the Space weather site each morning to see where the spot was in their picture but it was not in the same location as I saw in the morning - I just thought it was a fun exercise and really enjoyed being able to see the spot - hope to do it again will keep watching - thanks for your help and info

Think about it: When the Sun rises, the first part of it that first rises above the horizon will also be the first part to touch the opposite horizon in the evening sunset.

Therefore, a sunspot that is in the lower right portion at sunrise will be in the upper left portion at sunset.
