International Space Station Passages The Next Couple Of Weeks

April 6, 2015 0 Comments

There are a couple of really good chances to see a passage of the International Space Station here in Rochester in the next couple of weeks. There are three main factors in whether we will get to see the ISS: cloud cover, magnitude (brightness), and elevation. The ISS is the third brightest object in the sky after the sun and moon. What to look for is a steady bright dot moving slowly across the sky.

The first passage will start on Tuesday at 8:31 pm CDT and will last 7 minutes. The ISS will be coming from the west-southwest (245 degrees) and reach an elevation of 72 degrees. The question is will we be able to see it? We are forecasting ample cloud cover and rain showers for Tuesday night so there will not be a great chance to see this passage.

Our better shot at getting to see the ISS will be next Friday (April 17). This passage will start at 9:35 pm CDT and last 4 minutes. The ISS will be moving from the west-northwest (303 degrees) and reach an elevation of 81 degrees. Forecasting cloud cover eleven days out is not very accurate so we will keep you updated on the chances to see the ISS passage next Friday.
