If skies clear as expected by tomorrow (Wednesday) night, everyone in the Baltimore area should get a good opportunity to watch the International Space Station fly over. Beginning just after 8:10 p.m., look to the west northwest for a steady dot of white light, moving smartly toward the southeast. It looks like a high-altitude jet aircraft, except that it won't have any colored wing lights or flashing strobes. At 8:13 p.m. it should be 51 degrees above the southwest horizon (a bit more than halfway between the horizon and directly overhead). It will fade to black a minute later above the southeastern horizon as it moves out of the direct sunlight into the Earth's shadow. Hard to believe there are two people aboard that thing - one American and one Russian. Who ever gives them a thought these days?
