Weather is expected to be accommodating for viewing Tuesday evening's launch of a U.S. Air Force Minotaur 1 rocket, scheduled to lift off in a 7:30 p.m. to 9:15 p.m. window from a flight facility in Virginia.

The ORS-3 mission aims to launch 29 tiny satellites into orbit, including a smartphone and a 2-pound satellite built by high school students in Virginia.

Sky watchers looking to the south can expect to see the rocket once it clears the horizon, streaking up and arching across the sky, moving from right to left, said Bill Bogardus, president of the Custer Institute and Observatory in Southold.

There should be "a nice, clear south to southeast view" with the rocket appearing to those on Long Island shortly after it launches from the National Aeronautics and Space Administration's Wallops Flight Facility, he said.

That time lag, caused by curvature of the earth, should be about two minutes, according to a NASA flight visibility map.

Tuesday night's sky cover is expected to be about zero percent, making it "about as clear as we can get" for viewing, said David Stark, National Weather Service meteorologist based in Upton.

Part of the rocket's mission is to deploy 29 satellites into space, according to the NASA website.
