Kandilli tracking sunspots by hand for 79 years

Researchers at Turkey's Kandilli Observatory have been manually recording sunspots by hand since 1947, using a traditional method that continues to provide valuable data. The practice involves projecting the sun's image onto paper to map surface features, which are then sent to international data centers for analysis. This manual approach, developed by the observatory's founder Fatih Gökmen in 1920, uses a 20-centimeter telescope and avoids the need for protective filters, resulting in higher-resolution data compared to modern camera methods. Despite advances in technology, the observatory maintains this traditional technique to ensure accurate and enduring scientific records. TÜBİTAK, the Turkish Scientific and Technical Research Council, regularly hosts public observation events to promote awareness of space science.

The Perseid meteor shower reached its peak over Turkey overnight, offering stargazers one of the best opportunities to witness the celestial event in recent years. According to the Boğaziçi University’s Kandilli Observatory, the low illumination of the moon, only 1.8 percent lit, created optimal conditions for viewing the meteor shower, which has been visible globally and within Turkey for several days leading up to the peak. Observers in Turkey can expect to see meteors streaking across the sky during the early morning hours, with the main activity concentrated between 5 am and 7 am local time. The meteor shower began to be visible earlier in the evening, with the first meteors appearing around 7:50 pm in Turkey’s eastern regions and approximately 8:45 pm in the western parts of the country. While the Perseids remained visible throughout the night, the viewing experience improved significantly after midnight due to the decreasing light pollution and the absence of moonlight. This allowed for clearer skies and better visibility of the meteors as they entered Earth’s atmosphere. Astronomers noted that the timing of the peak coincided with the approach of dawn, meaning that the best period for observation would fall between 2 am and 5 am. During this window, the sky was darkest, reducing interference from ambient light and allowing for more frequent sightings of the meteors. The observatory recommended that viewers find a location away from city lights to maximize their chances of seeing the shower in full effect. The Perseid meteor shower occurs annually when Earth passes through the trail of debris left behind by Comet Swift-Tuttle. Each year, the shower produces up to 100 meteors per hour under ideal conditions, though the actual number can vary depending on atmospheric conditions and the observer’s location. This year, the combination of a dark sky and minimal lunar interference made the event particularly notable for observers in Turkey. The Kandilli Observatory emphasized that the current viewing conditions were among the best in recent years, owing to the new moon phase. The lack of moonlight reduced glare and allowed for greater clarity in observing the meteors. This was especially beneficial for amateur astronomers and casual observers who wanted to witness the spectacle without the need for specialized equipment. Across Turkey, astronomy enthusiasts and members of the public gathered in open spaces, mountainous regions, and coastal areas to watch the meteor shower. Some groups organized special events, including live broadcasts and educational sessions explaining the science behind the phenomenon. Local media reported increased interest in stargazing, with many people venturing outside despite the cool temperatures to catch a glimpse of the celestial display. The Perseid meteor shower is expected to remain active for several nights following the peak, with the number of meteors gradually declining as Earth moves further away from the comet’s debris field. However, the best chance to observe the highest number of meteors occurred during the early morning hours of the peak night. Weather conditions played a crucial role in determining how clearly the shower could be seen, with clear skies being essential for optimal viewing.

Perseid meteor shower to peak over Turkey

The Perseid meteor shower is expected to reach its peak over Turkey during the early hours of the morning, offering optimal viewing conditions due to minimal moonlight. The observatory reports that the moon will be only 1.8% illuminated, creating some of the best viewing opportunities in recent years. While the shower will be visible throughout the night, the best conditions are anticipated after midnight, with the main peak occurring between 5 am and 7 am. Observers in Turkey's eastern regions can expect to see meteors as early as 7:50 pm local time, while those in western areas may see them slightly later at 8:45 pm. The ideal viewing window is estimated to be between 2 am and 5 am before dawn.

Bias read (Center): The article presents factual information about a natural astronomical event without any political implications. It focuses on scientific observations and timing of the meteor shower, using data from a reputable observatory. There is no indication of ideological framing or emphasis on specific groups

Why factuality (95): The article accurately reports the timing and visibility of the Perseid meteor shower based on information from Boğaziçi Observatory's Kandilli Observatory. It provides specific times for when the shower will be visible and mentions favorable viewing conditions due to minimal moonlight. These detail

Why objectivity (90): The tone remains neutral and informative, presenting facts without emotional language or bias. However, the phrase 'some of the best conditions' may slightly imply a positive judgment rather than purely descriptive language.

Perseid meteor shower to peak over Turkey overnight

The Perseid meteor shower is set to reach its peak over Turkey during the night, offering optimal viewing conditions due to minimal moonlight. According to the Boğaziçi Observatory's Kandilli Observatory, the moon will be only 1.8% illuminated, creating some of the best conditions for observing the annual event in recent years. The meteors will be visible starting around 7:50 PM local time in Turkey's eastern regions and approximately 8:45 PM in the western parts. The main peak is anticipated between 5 AM and 7 AM, although the most favorable viewing period will likely occur between 2 AM and 5 AM before daylight begins to interfere.

Bias read (Center): The article discusses a natural astronomical event, the Perseid meteor shower, which is not inherently politically charged. It provides factual information about viewing conditions and timing based on observations from the Boğaziçi Observatory's Kandilli Observatory. There is no indication of bias,议

Why factuality (95): This article mirrors the first in content and sources, confirming the accuracy of the information about the Perseid meteor shower's peak over Turkey. It includes the same data about moon illumination and viewing windows, supporting the cross-source consensus.

Why objectivity (90): The language is consistently neutral, focusing on observational details without introducing subjective commentary. Like the first article, it maintains an objective tone throughout.
