Acquired from the collection of a NASA JPL Astrophysics archive most of these photos focus on the sun and moon (C.1970-80). This photo was shot and printed by the scientist for study. What makes this collection unique is the informal and formal documentation that went on in his study. This particular image was a beautifully shot solar flare activity. We have a nice variety of photos from this archive that will be listed separately. Measures 8” x 10” with some development staining ,wear, and a deep lower crease.
