Here is my weekly weather quiz question for the last time. What is the “Photosphere?” Here is the correct answer. The Photosphere is the intensely bright portion of the sun visible to the unaided eye; the “surface” of the sun. Reaching temperatures estimated at about 11,000 degrees Fahrenheit, it is the portion of the sun’s atmosphere which emits continuous electromagnetic radiation.
