# Geographical pole

A geographical pole or geographic pole is either of the two points on Earth where its axis of rotation intersects its surface. The North Pole lies in the Arctic Ocean while the South Pole is in Antarctica. North and South poles are also defined for other planets or satellites in the Solar System, with a North pole being on the same side of the invariable plane as Earth's North pole.
Relative to Earth's surface, the geographic poles move by a few metres over periods of a few years. This is a combination of Chandler wobble, a free oscillation with a period of about 433 days; an annual motion responding to seasonal movements of air and water masses; and an irregular drift towards the 80th west meridian. As cartography requires exact and unchanging coordinates, the averaged locations of geographical poles are taken as fixed cartographic poles and become the points where the body's great circles of longitude intersect.
# 1PN51

1PN51 (Russian: 1ПН51) is the GRAU index for a Soviet designed passive night scope for a range of Soviet designed small arms and grenade launchers. 1PN is the GRAU index of night vision devices, where PN stands for Nochnoy Pritsel (Russian: Ночной прицел) meaning night sight.
The scope weighs 2.1 kg and measures 276 mm × 210 mm × 140 mm (length × height × width).
It is attached onto a matching side rail on the weapon after which a lever on the scope is pressed to hold it in place.
The 1PN51 comes in a metal container with room for extra batteries, battery charger and the other accessories, weighing 6.45 kg in total.

## Optics

The scope gathers light via an 80 mm aperture into a reflector with the secondary mirror obscuring the central 42 mm of the aperture.
For zeroing the sight the top of the scope has two perpendicular knobs, of which the elevation knob has a detachable scale. The scope comes with eight different, detachable elevation scales for the supported weapons.
The aperture cover itself has two 12 mm apertures that can be opened partially allowing the scope to be used in light conditions that would otherwise saturate the light intensifier.
The rear end of the scope is a focus dial.
The eyepiece has a detachable soft rubber eyecup.
The scope has a magnification of 3.46.

## Light Intensifier and Reticle

On the left below the aperture the device has a brightness knob. Apart from powering on and off the device, this knob controls the brightness of the reticle allowing for the reticle to be visible without outshining the target.
The reticle has markings that match targets of various heights from 0.3 m to 2.7 m at distances ranging from 100 m to 970 m. This is similar to the reticle of the 1PN58.

## Power

The light intensifier is powered by a pack of 5 D-0,55S (Russian: Д-0,55С) rechargeable cells, providing up to 7 V. The scope requires 6.25 V. The maximum current drawn is 40 mA.
The D-0,55S battery pack is used by a range of devices including 1PN51-2 and 1PN58 and has a separate charging device. The charging device has a switch to select one of 12 V or 27 V input and two red control lamps, one to indicate that power is available and one to indicate that charging is complete.

## Supported Weapons

As of 1992 the 1PN51 can be used with the following weapons (weapons on the same line share the elevation scale):
SVDN-1,
AK-74N (AKS-74N),
PKMN-1 (PKMSN-1),
RPG-7N1 (RPG-7DN1),
AKMN-1 (AKMSN-1),
RPK-74N (RPKS-74N),
AKS-74UN (no elevation scale),
RPKN-1 (RPKSN-1),
VSS Vintorez, AS Val,
AK-103N2 (AK-103N2).

# Gobba di Rollin

Gobba di Rollin (Italian, French: Dos de Rollin; 3,898 m) is a mountain of the Pennine Alps, straddling the border between Switzerland and Italy. It is located south of the Breithorn and it is largely covered by ice, the summit area being particularly flat. On the north side is the Breithorn Plateau of the Theodul Glacier, on the east side is the Verraz Glacier and on the south is the Glacier d'Aventine.
Gobba di Rollin is notable as having the highest ski lift in Europe on its top, since it is the highest point of the ski area Matterhorn Glacier Paradise on the Theodul Glacier, between Zermatt and Breuil-Cervinia. It is connected to both the Klein Matterhorn and Testa Grigia by ski lifts. The shortest access is from the Klein Matterhorn station (3,820 m), less than two kilometres away, from where it can be easily reached by a piste on the glacier. The summit has even been reached via the Theodul Pass by 4x4 vehicles, a European record.

# Caladenia arenaria

Caladenia arenaria, commonly known as the sand-hill spider orchid, is a plant in the orchid family Orchidaceae and is endemic to New South Wales. It is a ground orchid with a single, densely hairy leaf and one or two white or pale yellow flowers with maroon tips. Formerly much more widespread, it is now only known from about two thousand individual plants in five locations in the Riverina area and is classed as "Endangered".

## Description

Caladenia arenaria is a terrestrial, perennial, deciduous, herb with a single underground tuber which is replaced annually. In late autumn or early winter a linear to narrow lance-shaped leaf is produced which is 15 cm (6 in) long, 6 mm (0.2 in) wide and reddish at the base.
One or (rarely) two pale yellow to creamy-white flowers are borne on a hairy spike up to 40 cm (20 in) high. The dorsal sepal, lateral sepals and petals are up to 80 mm (3 in) long, held horizontally or slightly drooping and tapering to dark reddish, thread-like ends. The labellum is egg-shaped to heart-shaped, about 18 mm (0.7 in) long and 10 mm (0.4 in) wide with teeth up to 3 mm (0.1 in) but decreasing in size towards the front of the labellum. There are four to six rows of calli, shaped like golf stick heads on the centre of the labellum. Flowering occurs from late August to November.

## Taxonomy and naming

Caladenia arenaria was first formally described by Robert FitzGerald in 1882 and the description was published in his book, Australian Orchids. The specific epithet (arenaria) is a Latin word meaning "sandy".

## Distribution and habitat

Sand-hill spider orchid grows in sclerophyll forest and on sandhills, usually under cypress pine trees. Its range used to extend for 500 km (300 mi) from Deniliquin to Yass and Mudgee but is now only known from five locations between Urana and Narrandera.

## Conservation

Caladenia arenaria is listed as "Endangered" under the New South Wales Threatened Species Conservation Act and under the Commonwealth Government Environment Protection and Biodiversity Conservation Act 1999 (EPBC) Act. Five populations with a total of about two thousand individual plants are known. Weeds, grazing and hybridisation with other orchid species are the main threats to the survival of this species.
# Dennis Hobden

He was re-elected in 1966 but lost his seat in 1970 to the Conservative Andrew Bowden. In 1974, Hobden attempted to regain the seat in both the February and October general elections, but was unsuccessful.
