Date of sighting: April 29, 2015
Location of sighting: International Space Station ISS
This UFO is the same UFO that was recorded at the space station on April 24th. It looks like this object either visits often or is nearby following the ISS. Streetcap1 of Youtube recorded it and this time its much more clear and much closer. NASA notices it slowly and then zooms in on the UFO, but it is unclear if NASA went to blue screen afterwords or if the feed just was cut off.
The fact that NASA noticed it and zoomed in on it gives us evidence that this was a UFO and they were worried about it. This zooming in tells us that NASA didn't expect the UFO and had concerns. SCW
As you can see in the photo above and below. The UFO is a solid looking object.
