gshTonight, between 22:43 and 22:49 EDT the ISS will pass from southwest to northeast, culminating 50 degrees above the northwest horizon at 22:46. It should be at least magnitude -2.5, and may "flare" even brighter if there's a good specular reflection from one of the solar arrays.
Tomorrow night, 7/7, between 21:32 and 21:38 EDT it will pass from southwest to northeast, culminating 44 degrees up in the southeast at 21:35. Since it will be viewed at a greater phase angle it should be brighter than tonight's pass, perhaps by a full magnitude. As an added bonus, there will be a bright "flare" of Iridium 32 at 21:31:37 near the bright star Vega. If you are ± a quarter mile of the USNO's longitude this flare could top out at magnitude -8. Farther east/west it will be less bright, but anywhere within ± 15 miles east/west of the USNO longitude it should still appear brighter than Venus.
On Wednesday, 7/8, between 21:57 and 22:02, we will once again have a southwest to northeast pass of the ISS, culminating 47 degrees up in the northwest just before 22:00.
