Bright white light in twilight sky.

Stepped outside shortly after sunset and noticed a bright white light in the southeast sky. Light was a little less than the apparent brightness of Venus, traveling at a high altitude about forty degrees above the horizon. The sky was still light enough that no stars were yet visible, though the crescent moon was clearly apparent in the southwest sky.
 Had time to grab my binoculars from my car. Through the binoculars, the light appeared to be a single steady point of light with no colored navigation lights or strobing.
 The light traveled in a straight line, moving at a steady speed from the southeast toward the northeast. It was visible for at least 90 seconds before fading in the distance. I thought it might have been the ISS, but checking with tracking apps showed the ISS wasn't due to be visible in my location in the NORTHWEST sky until several hours later.
