| Authors: | Osterbrock D E |
| Abstract: | Photoelectric measutements of the Hbeta intensity show that it continued to increase after a corona formed, and reached a maximum as the corona broke up into rays, decreasing rapidly to nearly zero within the next 10 minutes. The maximum flux of protons incident on the earth during the aurora, deduced from these measures, was at least 1.4 x 10(8) auroral protons per square centimeter, per second. |
