Polaris

Polaris (α Ursae Minoris, α UMi, commonly the North Star or Pole Star) is the brightest star in the constellation Ursa Minor. It is very close to the north celestial pole, making it the current northern pole star.

It is a multiple star, comprising the main star, α UMi Aa, which is a supergiant; two smaller companions, α UMi B and α UMi Ab; and two distant components, α UMi C and α UMi D. α UMi B was discovered in 1780 by William Herschel.

The revised Hipparcos parallax calculates the distance to Polaris at about 434 light-years (133 parsecs). Many recent papers derive distances up to 30% closer, particularly by assuming that its pulsation is in the fundamental mode. Deriving an accurate distance is especially important because Polaris is the closest Cepheid variable to Earth, so its physical parameters are critically important to the whole astronomical distance scale.

Star system

α UMi Aa is a 4.5 solar mass (M☉) F7 yellow supergiant (Ib). This is the first classical Cepheid to have a dynamical mass determined from its orbit. The two smaller companions are α UMi B, a 1.39 M☉ F3 main-sequence star orbiting at a distance of 2400 AU, and α UMi Ab (or P), a very close F6 main- sequence star with an 18.8 AU radius orbit and 1.26 M☉. There are also two distant components: α UMi C and α UMi D which have been shown to not be physically associated with the other three stars.

Polaris (convention)

Polaris (formerly Toronto Trek) is an annual science fiction and fantasy convention held in Toronto, Ontario, Canada in the past and now held in Richmond Hill, Ontario, Canada.

It began in 1986 as a relaxacon as Toronto Trek Celebration. Two years later, in 1988, Toronto Trek Celebration 2 took place. In 1989 it dropped the word "Celebration" and became simply "Toronto Trek". For its twenty-first convention in 2007, the name was changed to "Polaris". At Polaris 26, held July 5–7, 2012, it was announced Polaris had come to an end and that a new convention would replace Polaris in 2013.

The convention had a focus on media guests from science fiction, fantasy movies and television series and novel authors such as Star Trek, Babylon 5, Stargate, Doctor Who, Buffy the Vampire Slayer, Jericho, Lost and Battlestar Galactica. Photo opportunities, autographs and Question & Answer sessions feature the media guest, who sometimes come to other programming and after hours events.

USS Periwinkle (1864)

USS Periwinkle (1864) was a steamer procured by the Union Navy during the final months of the American Civil War. She served the Union Navy’s struggle against the Confederate States of America as a patrol gunship.

After the war, this ship was retained by the U.S. Navy to support the Hall Scientific Expedition to the Arctic Ocean, and during this voyage – under her new name Polaris – she proceeded into Arctic waters, only to have her hull crushed by the ice.

Construction

America, a heavy screw tugboat built at Philadelphia, Pennsylvania, in 1864, was purchased by the Union Navy 9 December 1864 from John W. Lynn; renamed Periwinkle; and commissioned early in January 1865, Acting Master Henry C. Macy in command.

Assigned to river patrol in the Potomac River

The two-masted, schooner-rigged, white oak tug joined the Potomac Flotilla 15 January 1865 as a gunboat, and operated primarily in the Rappahannock River.

In mid-March, a fleet of oyster schooners operating in the area was threatened by a Confederate enemy force, and Periwinkle with USS Morse, blockaded the mouths of the Rappahannock and Piankatank rivers to protect them. The Flotilla also interrupted contraband business between lower Maryland and Virginia, and cleared the rivers of mines, and fought guerillas ashore.

Coronado Ii

by: Polaris

It's kind of a low blow,
Not the one I got, but the one you gave.
It's really to soon to know,
How much of you will there be left for me to say.
He's a scallywag,
I have another friend that he did the same thing to,
And then he brags
And he'll kiss and tell me, kiss and tell me every time
you do.
Monte Carlo,
Coronado II,
And San Diego Zoo or a hundred nights with you won't
change my mind.
You rang and she called early,
You were laughing and she was asking "can we still be
friends".
You would like to think in Summer time you'll remember
So I'll never, never land where the stories never ever
ever.......
Monte Carlo,
Coronado II,
And San Diego Zoo or a hundred nights with you won't
change my mind.
Hey Monte Carlo,
Coronado II,
And San Diego Zoo or a hundred nights with you won't
change my mind,
