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.

Porrima (29 Gam Vir) in Vir [HIP 61941]

Distance: 39 light-years, Magnitude: 2.74

This star system in Virgo has the traditional names Porrima, Postvarta and Arich. Both components are 3.5 magnitudes bright and circle each other in 172 years. As the two stars are currently approaching for quite a while they will be difficult to see with small telescopes.

WISE 1049-5319 (Luhman 16) in Vela

Distance: 7 light-years, Magnitude: 14.94

In March 2013, a pair of brown dwarfs has been discovered on a map of the entire sky produced by the WISE satellite. With a distance of 6.58ly, it is the closest neighbor of the Sun that has been found in nearly a century. It is only slightly more distant than Barnard's star, which is the second nearest known system. Luhman 16 is also the nearest known star/brown-dwarf system to Alpha Centauri, located 3.63 ly from it. Luhman 16 is located in the southern constellation of Vela. The secondary,B, orbits in 3 AU with a 25 years period. In January 2014 astronomers map out clouds on the surface of Luhman 16B and created a map of dark and light patches. Temperatures in the clouds of Luhman 16B are 927°C. The clouds are probably comprised of iron and silicate minerals in a largely hydrogen-helium atmosphere.

M50 (Open Cluster) in Monoceros

Magnitude: 5.9

Located about 3,200 light-years away, this gathering of 200 stars is some 20 light years across, while the central concentration spans roughly 10 light-years.

Tucana (southern), area rank: 49

Invented in the 17th century by astronomer Johann Bayer, this constellation can be seen in autumn at the horizon at northern latitudes below 20 degrees. A toucan is a bird with a large nib living in the jungles of Latin America. Tucana is home to the globular star cluster 47 Tucanae, 120 light-years across and the second brightest known after Omega Centauri.

63P/Wild 1 (2013)

First detected by Paul Wild on a photographic plate exposed on 26 March 1960, who estimated its brightness at a magnitude of 14.3. Its elliptical orbit was then calculated to have an orbital period of 13.21 years. The 2013 return was moderately favorable with magnitude again around 12. [Wikipedia]

 

 

2010 CF19 (NEO)

Semi-major: 1.19425 AU, Size: 0.15 km

2010 CF19 is a 90 to 280 meters wide Apollo-type NEO Asteroid with a period of 1.31 years.

 

 

Epimetheus (moon of Saturn)

Discovered in 1966, Epimetheus and the neighboring moon Janus have been referred to as the Siamese twins of Saturn because they revolve Saturn in nearly the same orbit. Epimetheus and Janus may have formed by the break-up of one moon. Epimetheus, 135 x 108 x 105 km in size, has several craters larger than 30 km, including Hilairea and Pollux.

 

 

HAT-P-17 c (in Cygnus)

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.
