is Bigelow Genesis-I big enough for naked eye?
Hello everyone,
Considering it's inflatable and has solar panels, is it large enough (15' length, 12' diameter) to be seen with naked eye? Thanks!

Yes, it is visible to the unaided eye under favourable circumstances. Based on its dimensions, and assuming typical reflectivity, I had estimated a standard magnitude of 6.2 (at 1000 km, 90 deg phase angle), which under ideal circumstances would yield an observed magnitude of 4.5. I am aware of only one observation report, so far. Russell Eberst observed it on a less than ideal pass at mag 3.7, about 2.5 magnitudes brighter than my std mag predicted. Ted Molczan |

It was about fourth magnitude, and while the near-full moon made observation difficult, I could track it with the naked eye. --Bill Thompson |

I would think so, though I don't know what colour it is. Might be made of dark material ;-) Have the orbital elements been posted yet? The only thing I've found is the inclination (64 degrees, so it should be visible to almost everyone on Earth). The Genesis on Heavens Above is another satellite |
