The animation
covers a three day time period leading up to the day when the bright moon
Titiania occulted a magnitude 7.2 star. Although I could not see
the occultation from my location in Northern Virginia, USA, I could see
Uranus come very close to the star. This occurs in frame three of
the animation.
The image with
the horizontal lines was made by slewing the LX 200 while the MX-5C CCD
was exposing. This caused both Uranus and the star to trail.
The image was taken during the 10 minute period when the moon would have
passed directly in front of the star.
Had I been
able to see the occultation, the star would have dimmed several magnitudes
as the moon passed in front of it. This would have lasted from 30-50
seconds. Since I could not see the actual occultation, the brightness
of the star trail says constant through out the exposure. Click
