  The whole Sun.  Move your mouse pointer over the image to see the designations of the spots.  At the time I made this image, spot 11565 was new and did not have an official designation.  Fortunately my guess was right.  Looking at the SOHO pictures, I can see this spot first on the picture taken at midnight (20120903_000000).

Date and Time: 3 September 2012 10:37 UT
Camera: DMK 21AF04
Telescope: 270 mm SLR
Capture: ICCapture. Exposure 1/308", gain 737, 1693 frames
Processing: Registax6. 2 alignment points, 150 frames stacked per point. Gaussian wavelets Scheme 1, gamma 1.5, histogram 50-210.
  This is group 11560, the largest group visible today. 

Date and Time: 3 September 2012 11:13 UT
Camera: DMK 21AF04
Telescope: LX200-10 with Astronomik SII filter
Capture: ICCapture. Exposure 1/154", gain 737, 1680 frames
Processing: Registax6. 3 alignment points, 150 frames stacked per point.   Histogram 50-175, wavelets 1-2=10

  This is group 11564, another large group of small spots. 

Date and Time: 3 September 2012 11:13 UT
Camera: DMK 21AF04
Telescope: LX200-10 with Astronomik OIII filter
Capture: ICCapture. Exposure 1/154", gain 737, 1680 frames
Processing: Registax6. 3 alignment points, 150 frames stacked per point.   Gaussian wavelets Scheme 4.
   PhotoImpact. Contrast 40.

  This is group 11565, at this time only about 11 hours old.  It did not get much bigger than this and, to my eyes, had disappeared again by the 7th of September.

Date and Time: 3 September 2012 10:55 UT
Camera: DMK 21AF04
Telescope: LX200-10 with Astronomik OIII filter
Capture: ICCapture. Exposure 1/250", gain 647, 1722 frames
Processing: Registax6. 2 alignment points, 150 frames stacked per point.   Gaussian wavelets Scheme 8.
   Focus Magic 6,100.

  This is group 11553, a single large spot about to disappear around the eastern limb.  Sunspots are depressed into the surface of the Sun and you can just see that as they round the limbs.

Date and Time: 3 September 2012 10:58 UT
Camera: DMK 21AF04
Telescope: LX200-10 with Astronomik OIII filter
Capture: ICCapture. Exposure 1/250", gain 647, 1680 frames
Processing: Registax6. 1 alignment point, 150 frames.
   Wavelets 1-2=10, histogram 20-160
