In 3 years of postcrossing, this is my 1st aurora borealis card and this was one of my favorite cards. I'm really happy that Paula "xpaula" sent it to me :)
"Auroras, sometimes called the northern and southern (polar) lights, are natural light displays in the sky, usually observed at night, particularly in the polar regions. They typically occur in the ionosphere. They are also referred to as polar auroras. In northern latitudes, the effect is known as the aurora borealis, named after the Roman goddess of dawn, Aurora, and the Greek name for north wind, Boreas, by Pierre Gassendi in 1621. The aurora borealis is also called the northern polar lights, as it is only visible in the sky from the Northern Hemisphere, the chance of visibility increasing with proximity to the North Magnetic Pole, which is currently in the arctic islands of northern Canada. Auroras seen near the magnetic pole may be high overhead, but from further away, they illuminate the northern horizon as a greenish glow or sometimes a faint red, as if the sun were rising from an unusual direction. The aurora borealis most often occurs near the equinoxes; from September to October and from March to April.
Auroras can be spotted throughout the world. It is most visible closer to the poles due to the longer periods of darkness and the magnetic field.
Its southern counterpart, the aurora australis or the southern polar lights, has similar properties, but is only visible from high southern latitudes in Antarctica, South America, or Australasia. Australis is the Latin word for "of the South." - in: wikipedia

Yeoman Warders began guarding the Tower in 1485; today there are 35 Yeomen Warders and one Chief Warder. All warders are retired from the Armed Forces of Commonwealth realms and must be former senior non-commissioned officers with at least 22 years of service. They must also hold the Long Service and Good Conduct medal." - in: wikipedia
"Lonar Lake, which was created by a meteor hitting the Earth during the Pleistocene epoch, is a saltwater lake in Buldana district, Maharashtra, India. The crater thereby formed is the only hypervelocity meteoritic impact crater on basalt rock. A lake that evolved in the resulting basaltic rock formation, is both saline and alkalie in nature. Geologists, ecologists, archaeologists, naturalists and astronomers have reported several studies on the various aspects of this crater lake ecosystem. Lonar Lake has a mean diameter of 1.2 kilometres (3,900 ft) and is about 137 metres (450 ft) below the crater rim. The meteor crater rim is about 1.8 kilometres (5,900 ft) in diameter. The circular depression bears a saline water lake in its central portion. The crater's age is estimated to be 52,000 ± 6,000 years (Pleistocene). It is the second largest impact crater in basaltic rock and is partially filled by a salt water lake." - in: wikipedia
