>I might sit down and do the math to see how 1500 satellites at mag 6 compares to 60 at mag 2. Every 5 astronomical magnitudes corresponds to a factor of 100 difference in brightness, so magnitude 2 is (100^0.2)^4 or about 40 times brighter than magnitude 6. So they're pretty similar, 1500 satellites at magnitude 6 are about 2/3 as bright as 60 satellites at magnitude 2. |
