Social Media Buzz

Numerous videos from Siberia showing a spectacular flash in the sky are circulating on social media. The cause of the event is no mystery, nor is the fact that it posed no danger to us.

The “culprit” was a small asteroid that entered a collision course with Earth on December 3. The fireball seen in social media videos was the result of the asteroid burning up in Earth’s atmosphere.

Warnings from ESA

Interestingly, the European Space Agency (ESA) issued a warning about the approaching asteroid just hours before it entered Earth’s atmosphere. Experts emphasized that an object of this size posed no danger to people but promised a spectacular show.

“It’s small, but it will still be quite spectacular. Over the indicated area, it will be dark, and within a radius of several hundred kilometers, a very impressive, very bright fireball will appear in the sky,” explained Professor Alan Fitzsimmons from Queen’s University Belfast, an expert in asteroid and comet science.

Video Footage on Twitter

The event was also captured in a Twitter video, showcasing the breathtaking sight:

A Positive Sign

The asteroid, temporarily designated as C0WEPC5, had a diameter of approximately 70 cm and appeared over northern Siberia. ESA and other space agencies operate numerous sensor networks around Earth, allowing them to detect incoming objects like C0WEPC5.

Professor Fitzsimmons noted, “Our ability to detect objects before they impact Earth is growing,” highlighting this as another positive sign.






100-Year-Old Dam in Zagórze Śląskie Malfunctions

Urgent Repair Efforts Underway

For several days, employees of Tauron Ekoenergia have been working intensively to address a malfunction in one of the sluices on the dam in Zagórze Śląskie. The problem arose during routine maintenance when one of the four sluices failed to return to its position and got stuck in the open position, leading to an uncontrolled flow of water.

Repair efforts underway at Zagórze Śląskie Dam

Historical Significance

The dam on Lake Bystrzyckie, built in the early 20th century by the Germans, is over 100 years old and remains a vital piece of infrastructure. Despite its age, it plays a key role in flood protection and providing drinking water to surrounding towns such as Dzierżoniów and Bielawa.

“This device is over 100 years old, so it has the right to fail. After extensive expert consultations, our employees have determined how to repair the sluice and stop the continuous water flow,” representatives told *Gazeta Wrocławska*.

The Temporary Fix: A Giant Plug

The repair is planned in two stages. The first step is to halt the uncontrolled water flow by constructing a sealing element, akin to a giant plug. Once the flow is contained, workers can proceed with repairing the damaged mechanism.

“A special sealing element is being constructed, resembling a giant plug to seal the area. The operation will commence in a few days once the structure is ready,” employees explained.

Importance of the Dam and Lake Bystrzyckie

The dam in Zagórze Śląskie is an impressive structure standing 44 meters tall with a crown length of 230 meters. It was initially built to protect against floods but now also serves as a recreational hub for residents of Wałbrzych, Wrocław, and Świdnica.

Residents wonder if the current situation will be used as an opportunity to continue cleaning Lake Bystrzyckie following the September flood. Actions so far have been limited, but the malfunction might present a chance to advance cleanup efforts.
