No promises here. The forecast is still not very encouraging. But if we get lucky, the International Space Station should be visible over Baltimore just after 7:30 this evening.

Here's the scoop:  The ISS, with three astronauts on board, will be tracking northeast tonight, from North Florida to Cape Hatteras, and then out to sea. It may sound geeky, but lots of people have gotten a kick out of watching their tax dollars zip across the sky. Drag the kids away from their video games and get them to help you watch for the flyover. They're often the first to spot it. Young eyes.

As seen from Baltimore, the ISS will first appear above the southwest horizon at 7:34 p.m. Watch for what looks like a steady bright star, moving brisky toward the east. If it has multiple, or colored lights, it's an airplane. Keep looking.

It will reach it's highest point - about halfway between the southeast horizon and the zenith (straight up) at 7:37 p.m. From there, the station will track toward the northeast, appearing to pass very close to the planet Saturn and the bright star Regulus, which are side-by-side above the eastern horizon at that hour. The ISS will then disappear on the southeast at about 7:40 p.m.

Regular satellite watchers say the ISS has become very much brighter since astronauts have added new modules, solar panels and radiators. It can be the brightest object in the night sky.

After watching the flyover, come back here and leave us a comment, and share the experience with those who missed it. If this one is clouded out, we'll have a better shot tomorrow night. Stay tuned.
