Nick was imaging the comet from his home observatory in Wiltshire as it was passed close to NGC 5907 in the constellation Draco, when he noticed that the comet's tail appeared to change in brightness between 15 and 16 March.
the vernal equinox was in the constellation Aries and the star Thuban (in Draco) was the closest bright star to the NCP.
223 synodic months (6585.321 days) almost equal 242 draconic months (6585.357 days), a period of 18 years 10 and 1/3 (or 11 and 1/3) days -- depending on the number of intervening leap years.

Grumium Creations used connections in the Draconis Combine to obtain permits to purchase large numbers of Shigunga LRM-20 and LRM-15 missile launchers, and built the chassis and internal workings of the Viking around them.
The "North Star" of the period was α-Draconis, also known as Thuban, though it was 2 away from true North at the time of Khufu.

the North Star was a star called Thuban (also known as Alpha Draconis), and in about 13,000 years from now the precession of the rotation axis will mean that the bright star Vega will be the North Star.
5,000 years ago it pointed at the star Thuban in the constellation Draco. In 14,000 AD, the "pole" star will be Vega in Lyra. It requires 26,000 years for the north celestial pole to complete one precessional circle around the sky.
It is widely believed that M102 may be a lenticular galaxy located in the constellation Draco. It is a dim object with a visual magnitude of only 9.9 and can be hard to find without dark skies and ideal observing conditions.
The shaft on the north side leads directly to the north celestial pole, which in Cheops' time corresponded to the star Thuban in the constellation Draco.
(red, hydrogen-alpha; blue, neutral oxygen, 6300 angstroms; green, ionized nitrogen, 6584 angstroms). The image was taken on September 18, 1994. NGC 6543 is 3,000 light-years away in the northern constellation Draco.
12,000 years from now"nearly halfway through one cycle of precession"Earth's axis will point toward a star called Vega, which will then be the "North Star." Five thousand years ago, the North Star was a star named Thuban in the constellation Draco.
Starspots can be either dimmer or brighter than surrounding regions. As a star with starspots rotates, its brightness changes slightly. Stars exhibiting such behaviour are called rotating variables. One type of rotating variables are the BY Draconis ...
