[John W (John Wilkinson)]

April 11th, 12 noon.
Sunspot 2738 on the NE limb of the sun. Image 1 was taken thru a Lunt 100 Ha refractor. Image 2 was taken thru a WO81 mm refractor with herschel wedge at 540nm. Both single exposures. I estimated the size of the spot to be 45,000 km. Thanks for viewing.
