Brightest Satellites
Satellites are visible when the sky is dark and the satellite is able to reflect sunlight back to the observer. These conditions generally occur up to about 45 minutes before sunrise (before the sky becomes too light) and 45 minutes after sunset. These satellites (or objects) are normally brighter than magnitude 4. If your latitude is close to or below the inclination of a given sat, it will be potentially visible at your location.
