Yes - very faint! Four times farther than the moon! It's pretty hard to see objects in geosynch orbit and this would be about 40 times farther away than geosynch. On the other hand it should be almost always flaring as the solar panels and sun shield will face back towards both the earth and the sun which are all lined up. So if a geosat can flare to mag 4, and this is 40 times farther away, wouldn't it be 40^2 times fainter (1600 times fainter) or about 8 magnitudes fainter? - George Roberts http://gr5.org ----- Original Message ----- From: "Kevin Fetter" <kfetter@yahoo.com> To: <seesat-l@satobs.org> Sent: Monday, December 14, 2009 8:08 AM Subject: how bright would the James Webb scope be > Some one asked on another list, who bright the James Webb scope be. > > Info on the space telescope. > > http://www.jwst.nasa.gov/about.html > > I said it would be faint, but I could be wrong. > > Kevin > > > __________________________________________________________________ > Looking for the perfect gift?
