U.S. Air Force Senior Airman Erin O’Connell, Detachment 4, 2nd Weather Squadron solar analyst, uses a white light board to observe the size of solar spots on the sun at the Holloman Air Force Base, N.M., solar observatory June 7. Although many spots appear small when projected by the machine, solar analysts use scales to show how massive the spots are in comparison to other planets.
