1. This web site is target of "Distributed Denial of Service (DDoS)" attack intended by criminals to exhaust the resources of a hosting server. It is a high frequency random access to all web files in the site directory, a classic tactic, aiming to degrade or crash hosting infrastructure. This website is the entry point, but the real goal is to overwhelm the web server or shared hosting environment. Most of the attacking IP addresses originate in the PRC, either on purpose to blame China or it is real. My provider, Hostgator, does not seem to be interested in deeper investigation, instead suggesting the service of "Cloudflare". Even if the contents of the site isn't sensitive, the attack is criminal calling for harsh punishment. This attack also falsifies the visitor access log, wondering what this human garbage is trying to accomplish besides display of sick brains.

2. Certain people appear to enjoy filling forms with random letters for no purpose but insane self-satisfaction. Most of this stupid folks leave their IP addresses which are forwarded to their provider companies. All so received forms are automatically deleted. Sadly, the world is overfilled with idiots, trolls and criminals. This is a public web site without any sensitive data. No need for these irrational displays.

3. Now in the process of changing all large images to AVIF or WEBP format resulting in considerably reduced file size and download time hardly sacrificing quality as compared with JPEG.

Erakis (Mu Cep) in Cep [HIP 107259]

Distance: 5261 light-years, Magnitude: 4.23

Erakis, Mu Cephei, and also called the Garnet Star, is a class-M supergiant star that has swollen to 650 solar radii, one of the largest naked eye stars in our sky. If placed in the solar system, its outer shell would extend beyond the orbit of Jupiter, perhaps Saturn, as it may be larger than estimated. Also its distance is uncertain, some 6000 light-years assumed. The star is near the end of its life, currently fusing helium into carbon. A star of this size may leave a black hole after going nova.

GJ 406 (Wolf 359) in Leo

Distance: 8 light-years, Magnitude: 13.5

Wolf 359 is a red dwarf and a flare star exhibiting absorption lines of water and titanium (II) oxide in its spectrum and emits strong bursts of X-ray and gamma ray radiation. The surface with an effective temperature of 2800K (low enough for chemical compounds to form and survive) has a magnetic field that is stronger than the average magnetic field on the sun.

M53 (Globular Cluster) in Coma Berenices

Magnitude: 7.6

Heading towards us at a speed of 112 km/s, globular cluster M53 is one of the furthest distant globular clusters in our Milky Way midway our solar system and the galactic center. This 220 light-years diameter ball of stars in tightly compacted towards its core.

Sculptor (southern), area rank: 36

A constellation without distinctive stars located south of Cetus. Its constellation picture draws a plaster figure and a table with a chisel on it. In the 18th century, French astronomer Louis de Lacaille introduced Sculptor to fill up space between the constellations.

45P/Honda-Mrkos-Pajdusakova

Discovered on December 3, 1948, 45P/Honda-Mrkos-Pajdusakova is a short-period comet on an elliptical orbit with a period of 5.26 years. Its nucleus is estimated to be 0.5-1.6 kilometers in diameter. The comet made a close approach of only 0.06 AU (8,980,000 km) from the Earth on August 15, 2011.

 

 

Ryugu (Asteroid)

Semi-major: 1.18965 AU, Size: 0.914 km

Discovered on May 10, 1999 by the LINEAR project, Ryugu, formerly 1999 JU3, is a C-type Apollo asteroid, a rocky body expected to contain notable organic matter and water in its rocks. Its mean distance to the sun is 1.1895AU resulting in an orbital period of 1.3 years. It is therefore classified as near-Earth object (NEO) and potentially hazardous asteroid (PHA) of the Apollo group. Ryugu is approximately 1km in diameter (polar radius 440m) and has a mass of 450 million tons. It takes Ryugu about 7.627 hours to spin retrograde once around its axis. Due to 'seasons' the surface temperature varies between 30 and 100°C. Japan's Hayabusa 2 is designed to study asteroid Ryugu from multiple angles, using remote-sensing instruments, a lander and a rover. It will collect a surface, and possible subsurfaces materials from and return the samples to Earth in a capsule for analysis by December 2020.

 

 

Telesto (moon of Saturn)

Telesto is known as a Tethys Trojan because, together with Calypso, it circles Saturn in the same orbit as the moon Tethys, 60 degrees ahead of it. Telesto is about 32.6x23.6x20.0 km across and appears to have a smooth, icy surface. It does not show the signs of instense cratering seen on many of Saturn's other moons.

Dark Site in Morocco

Some say that the seeing is better only in space.

Click on the banner to visit the new website of SaharaSky, the first and currently only private observatory with Casbah-style *** hotel in North Africa.

 

The owner, Fritz, is a German with a life-long passion for astronomy. Then, as he felt in deep love with Morocco and its wonderful people, he built a self-contained hotel at the feet of the Sahara about 30 kilometers to the southeast of the town of Zagora entirely in the traditional southern Moroccan Casbah-style and equipped it, besides comfortable rooms, a restaurant, spa and sauna, with a rich portfolio of optical instruments and accessories for amateur astronomers.

Fritz chose the location extremely well, a truly dark site in absence of city and street lights, blessed with an average of 300 clear dry nights annually. The observatory atop the hotel building offers a 360 degrees panoramic view on 500 square meters.

Most guests are professional and amateur astronomers, but also people of all ages with affection for the fascination of the stars and the desert. From the hotel's wide roof terrace, everybody can enjoy the starry sky dominated by the arch of the Milky Way with bare eyes or with rental telescopes and cameras.

The heart and soul of SaharaSky's observatory is Patrick from Belgium, not only a senior professional astronomer, but also a talented animator and entertainer under the Saharan stars.

A stay at SaharaSky is not limited to the night sky. SaharaSky provides equipment for solar observation, but Fritz also organises desert excursions for several days, overnight or day-return treks in a 4x4 or on dromedar backs, plus guided tours to historically invaluable local sites, such as the Petroglyphs of Ait Ouazzik.

Owner and staff as a team speak Arabic, local Berber, English, French, German, Spanish and Dutch.

Scotty, lock on to the coordinates of SaharaSky and beam us over!


SaharaSky owns telescopes with apertures from 40 to 400mm, such as Takahashi APOs, each of which can be saddled on high precision GM2000 mounts featuring GPS, GoTo and accurate guiding for both, visual observation and photography.
