UARS was launched back in 1991
About an hour ago , it passed in front of the sun , from my location.
This tiny object was just 3.3" diameter at nearly 700 km range , but
flickered across the screen , the size of a single pixel.
I managed to capture the transit on video , however when converted to gif
format ( about 600kb) UARS is very faint.
Strangely , another object transitted at the same time , a little
larger......I suspect that may have been a bird :O) as Calsky does not list
any other sats for this time (It was about 8" so would have been quite large
if a satellite.
I won't be posting the video on my website , but if anyone wishes to se it ,
please drop me a note and I will forward it on
Here are the CalSky predictions....which were spot on !
