30 June - International Asteroid Day

Asteroid Day (also known as International Asteroid Day) is an annual global event which is held on the anniversary of the Siberian Tunguska event that took place on June 30, 1908, the most harmful known asteroid-related event on Earth in recent history.The United Nations has proclaimed it be observed globally on June 30 every year in its resolution. Asteroid Day aims to raise awareness about asteroids and what can be done to protect the Earth, its families, communities, and future generations from a catastrophic event. For example, 2014 HQ124, discovered April 23, 2014, went past 1,250,000 km from Earth the same year, June 8th, only 46 days after discovery, and 2015 TB145, went past at 490,000 km only 21 days after its discovery.

The International Asteroid Day is a global awareness observance that aims to educate and inspire people to know more about asteroids, their part in the formation of the universe, and how they can be useful. The observance was founded by the astrophysicist Dr. Brian May. In 2016, the asteroid day was officially observed by the United Nations. The observance occurs annually on June 30th.

30 June - NATIONAL METEOR WATCH DAY

Meteor Watch Day is observed every year on June 30th in the USA. Also known as National Meteor Day, on a cloudless night, people turn their eyes to the heavens in hopes of spotting the glow of a falling star. 

Daily there are millions of meteors that occur in the Earth’s atmosphere.

When space debris, such as pieces of rock, enter the Earth’s atmosphere the friction causes the surrounding air to become scorching hot. This “shooting star” streaking through the sky surrounded by flaming hot air is a meteor.

The majority of the meteoroids that cause meteors are only the size of a pebble.

Meteors sometimes occur in showers. It’s an excellent time to plan for a meteor-watching party. Whether we catch a few stray falling stars or witness an entire meteor shower, this day calls for an evening with friends and family under the stars. Identify the constellations while waiting to make a wish or two. Sounds like a romantic night, as well.

29 June - National Camera Day USA

Everything comes into focus on June 29th each year when we recognize Camera Day. The day commemorates photographs, the camera, and their invention. A camera is an irreplaceable tool used to record and replicate memories, events, and people/places. Before the invention of the camera, the only resource to document a vision was a painting. Capturing an image of a person or place in a drawing took time and skill. Very few people can perfectly draw the likeness of someone, let alone capture the essence of an event.

The power of a camera provided many with a simple, inexpensive, and fast solution. George Eastman, also known as “The Father of Photography,” brought the camera to the masses. While he did not invent the camera, he did develop many additions improving the use, ease, and production of the camera. His developments made the camera widely available to homes around the world.

Can you imagine a life where you couldn't capture the first dance at a wedding or a baby's first year or a graduation or one where there are no movie theaters? Here are some ways you can honor the humble device:

• Take your camera with you and record little moments of the day.
• Share the pictures you took on any of the photo sharing social website out there.
• If you have always wanted to learn about photography, today may be the day to start.
• Learn more about the history and science of cameras and photography

29 June - Prasanta Chandra Mahalanobis birth anniversary

Prasanta Chandra Mahalanobis was a distinguished Indian scientist and statistician, renowned for his pioneering work in the field of statistics and for his significant contributions to the development of modern statistical methods in India. He was born on  29 June 1893, in Calcutta, British India (now Kolkata, India), and he passed away on 28 June 1972.

Mahalanobis was educated at the University of Calcutta and later at the University of Cambridge, where he studied under renowned statisticians such as Ronald Fisher. He played a crucial role in establishing the Indian Statistical Institute (ISI) in Kolkata in 1931, which became a premier institution for statistical research and education in India.

One of Mahalanobis's most notable contributions to statistics is the development of the Mahalanobis distance, a measure used to quantify the distance between a point and a distribution. He also made significant contributions to the field of sample surveys, introducing innovative techniques that are widely used in survey research today.

In addition to his work in statistics, Prasanta Chandra Mahalanobis made significant contributions to various other fields, including economics, planning, and policy-making. He played a key role in shaping India's economic development strategies, particularly through his involvement in the Planning Commission of India.

Prasanta Chandra Mahalanobis's contributions to statistics and science have earned him widespread recognition and accolades, both in India and internationally. He was awarded the Padma Vibhushan, one of India's highest civilian honors, in 1968. He is remembered as one of India's greatest statisticians and intellectuals, whose work continues to influence research and policymaking in India and beyond.

28 June - King Edward IV crowned in 1461

  

Edward IV (28 April 1442 – 9 April 1483) king of England from 1461 until October 1470 and again from April 1471 until his death in 1483. He was a leading participant in the Yorkist-Lancastrian conflict known as the Wars of the Roses.

Edward was the eldest surviving son of Richard, duke of York, by Cicely, daughter of Ralph Neville, earl of Westmorland. His father was descended from two sons of the 14th-century king Edward III and, in the 1450s, led a revolt against Henry VI; in 1460, Richard’s supporters declared him Henry’s successor. When his father was killed in December of that year, Edward gathered an army in Wales and defeated Henry’s supporters (called Lancastrians because of Henry’s descent from John of Gaunt, duke of Lancaster). Edward was crowned as King Edward IV in London on June 28, 1461.

First modern dog show 28 -29 June 1859

The first modern dog show, on 28–29 June 1859 in Newcastle-upon-Tyne, was an added attraction to the annual cattle show. Its country character was clear, as only setters and pointers – sporting breeds – were shown and the prizes were guns. It was a low key start to what would be, by the end of the century, a hugely popular pastime, with dog owning fashionable among all classes of society, and which had huge implications for canine breeding.

The first show to include non‑sporting breeds was held in Birmingham later in 1859 and was such a success that a year later, the Birmingham Dog Show Society ran the first National Dog Show, for which there were 267 entries, with 30 breeds, judged in 42 classes. The main organiser was Richard Brailsford, a gamekeeper on the Knowsley estate of the Earl of Derby, then leader of the Conservative opposition and three-time prime minister. The earl’s pointer, Juno, won a prize in 1862, indicating how rapidly participation in dog shows spread to the country’s elite, making dog fancying fashionable and respectable. By the end of the 1860s, the National Dog Show was attracting over 700 dogs and 20,000 paying visitors.
