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 is set to reach its peak over Turkey overnight, offering optimal viewing conditions due to minimal moonlight. According to observations from the Boğaziçi Observatory’s Kandilli Observatory, the moon will be only 1.8 percent illuminated, creating one of the best opportunities in recent years to witness the annual meteor shower. The event is expected to provide clear skies and ideal visibility for stargazers across the country. The Perseid meteor shower has already been visible in Turkey and other parts of the world for several days. The meteors are anticipated to begin appearing around 7.50 pm local time (GMT+3) in the eastern regions of Turkey and slightly later, at approximately 8.45 pm, in the western areas. As the night progresses, the number of meteors is expected to increase steadily. The main peak of the shower is predicted to occur between 5 am and 7 am, though early morning hours will likely offer the best chances for observation before dawn. Despite the main peak occurring during the early morning, the Perseids will remain visible throughout the night. However, conditions are expected to improve significantly after midnight, making this period more favorable for viewing. Observers should note that while the shower can be seen all night, the highest concentration of meteors will be visible between 2 am and 5 am, just before sunrise. This timeframe offers the clearest view of the celestial display, especially for those located in central and western Turkey. The low level of moonlight is a key factor contributing to the favorable viewing conditions. With the moon being only partially illuminated, its brightness will not interfere with the visibility of the meteors. This makes the current year particularly advantageous for observers hoping to catch sight of the Perseids. The Kandilli Observatory has confirmed that these conditions represent some of the best in recent years, potentially allowing for a more intense and noticeable meteor shower than usual. The Perseid meteor shower occurs annually when Earth passes through the debris trail left by comet Swift-Tuttle. These particles, traveling at high speeds, burn up in the atmosphere, creating streaks of light known as meteors. The shower is typically active from mid-July to late August, with the peak usually occurring in August. This year’s peak coincides with the optimal viewing conditions, making it a prime opportunity for both amateur and professional astronomers to observe the phenomenon. As the night progresses, viewers are encouraged to find dark locations away from city lights to maximize their chances of seeing the meteors. While the main activity will take place in the early morning hours, the entire night presents a chance to witness the spectacle. Whether in urban settings or remote countryside, the Perseid meteor shower promises a memorable astronomical event for those who choose to look up at the sky.

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.

Bias read (Center): The article presents factual information about the Perseid meteor shower without any political framing, opinion, or bias. It focuses solely on astronomical data and observational conditions, making it apolitical in nature.

Why factuality (95): The third article presents identical factual information as the others, including the timeframes for visibility and the role of moonlight. This consistency supports the reliability of the information and aligns with the cross-source consensus.

Why objectivity (90): The article maintains a balanced and factual tone, avoiding any emotional or biased phrasing. It simply reports what is observable and supported by astronomical data.
