Each time step is a sidereal day, so the constellations stay fixed in the sky, but the local time progressively gets earlier. Tracks the comet's motion through the inner solar system as viewed from about 5 astronomical units from the Sun. Comet Hyakutake rises in the east over McCullough's backyard in Champaign, Illinois, on March 21st. Each of the 100 frames is a 5-second exposure.
Clouds cross the field of view from time to time.
Tim Puckett of Villa Rica, Georgia, has produced several videos of Comet Hyakutake and has graciously offered to let us post them here on SKY Online. You may have seen one or more of Puckett's time-lapse sequences on national television. During processing, the images were enhanced to highlight jets in the comet's tail.
