To check when it is visible, you can use www.heavens-above.com, it is listed under the Satellites category.
They also have an astrophotography contest, if you take a picture that includes the solar sail, whether it is a pictures of the sail through a telescope or if it's just a flare shot you can submit your photo and be eligible to win up to $500!! Details here:
Nasa's press relase:
Here's hoping it really does reach a ridiculously bright magnitude! I bet we'll get a lot of the general public freaking out over a bright thing in the sky too!

Hopefully the predictions of 5-10x venus' magnitude come true, that would be a site to behold!

To quote the web page:
"Unfortunately, at this particular moment it appears that the angle of the sail relative to the sun and to prospective observers on the ground will be rather unfavorable, and as a result NanoSail-D has been very dim; quite likely invisible to the unaided eye. "

---------------- * 57 deg/rad * 3600 arc-seconds/deg ~ 1
Using 3m for the length of one side of the sail, and 650km as the orbit height.
What exactly are they looking for in a photo of an unresolved object?
Sounds like they need it for photometry?

They said it would be visible in telescopes if you could track it moving so quickly and that you would be able to see move across the sky and take a photo of it streaking across the sky.
Maybe it'll still be possible to see it because it will become so bright?

we have a bright one coming up here in the northeast on the 15th. May try and see what I can come up with! A very cool object to track either way!
