Among the million visitors expected to flock to Oregon for a rare solar eclipse at the end of the month, is an unnamed man looking for a night of passion.

The unnamed 40-year-old took out an advertisement on Craigslist in search of a 'worthy' female companion with 'strong genes, beauty and smarts' to conceive a child with him on August 21.

The suitor with a 'strong and pure' European heritage said the woman must like cats in order to 'experience the totality eclipse' with him, but admitted he hasn't decided on an exact location yet.

But those willing to have a child on the 'next level of human evolution' will have trouble finding their would-be lover because the post was taken down.

An unknown man placed a Craigslist ad (pictured) looking for a lover to conceive a child with him during the total solar eclipse on August 21 in Oregon

The ad reads: 'I am 40 years of age, Caucasian male from Europe. My heritage is strong and pure.

'My looks, instincts, knowledge and strength is 100 per cent pure and 100 per cent lethal.

'I am looking for a worthy female with strong genes beauty and smarts. To join me - to experience the totality eclipse in Oregon. Exact place not set.

'If we have chemistry, I would like for us to make love while the eclipse is happening.

'When totality occurs, we will have simultaneous orgasms and we will conceive a child that will be on the next level of human evolution.

'We will make love together, with me and my penis directed towards the sun. Everything will be aligned in the local universe.'

The man continues: 'Both of our cosmic orgasmic energy will be aligned with the planets.

'In a brief moment of ecstasy, we will understand everything, and together create a new universe. Full of love...

'You must like cats. Drugs are OK. Nitrous Oxide while we climax and experience totality and conception, is OK with me.'

Nitrous oxide is commonly known as laughing gas and is not commonly known to be used during sex.

The August 21 event will be the first coast-to-coast total solar eclipse to cross the continental United States in 99 years and will first be visible in Oregon.

It is expected to attract one million eclipse chasers to the state, with officials bracing for as many as 100,000 of them in and around Madras, Oregon.

Madras is predicted to be among the country's best viewing spots because of its clear, high-desert skies, flat landscape and stunning mountain views.

A total solar eclipse will pass from coast-to-coast through the continental US for the first time in nearly a century on August 21. It will be visible to millions of people as it crosses through 14 states, with the path of totality stretching from Lincoln Beach, Oregon, to Charleston, South Carolina

The best views of totality will be along the red line, though it will be visible in areas within the purple as well. It will first be seen in Oregon

Every hotel in the town is already booked, some residents are renting their homes for $3,000 a night, and campers are expected to flood the national forests and grasslands during peak wildfire season.

The eclipse will be visible to millions of people as it crosses through 14 states, with the path of totality stretching from Lincoln Beach, Oregon, to Charleston, South Carolina.

During this time, the sun will be completely blocked by the moon, leaving only the 'pearly white rays' of its elusive corona visible to the naked eye – but, even in areas set to experience the longest duration of totality, the sun will only be fully covered for less than three minutes.

Scientists revealed many ways to prepare ahead, from what time the eclipse will pass through your city, to when you should put on your safety glasses.

While entirety of the event will only be seen along the 70-mile-wide path of totality, even viewers outside the range will be able to see a partial solar eclipse.

The latter will be visible all across North America, and even in parts of South America, Africa, and Europe, according to NASA.

Totality will cross the US from west to east, beginning at Lincoln Beach, Oregon.

There, the total solar eclipse will begin at 10:16 a.m. (PDT).
