Višnjan observatory (Croatia) star trails

The Višnjan Observatory, that is, the new observatory on Tičan hill, is the second most successful in detecting asteroids that could pose a threat to Earth, according to the recently published statistics by the Minor Planets Center of the International Astronomical Union.

Since the beginning of 2019, the Croatian team performed 54.5% of the work in monitoring the objects passing near the Earth that could pose a possible threat to it (Near Earth Objects - NEO). Thus, they are placed directly behind NASA, and in front of the US Army and the European Space Agency (ESA). The Legend of Croatian astronomy Korado Korlević, one of the most prolific asteroid hunters, says that astronomers sometimes joke, calling them the "Wallmart of World Astronomy" in the sense that they have the best price ratios concerning the product. Namely, they spend the least when the work accomplished is taken into account, since they do not have any institutional funding.

So far, more than 19,000 objects that run as NEO are known, and this number increases each month by another two hundred discoveries. Yet, this job is still not near completion. American astronomers from Hawaii, Arizona, California and South America form the backbone of the network for detection and follow-up, while Višnjan has become increasingly prominent as their essential ally in Europe.

"Among the American asteroid hunters, the Višnjan Observatory is labeled with the codename 'L01’. The Americans are not surprised by our success because there are plenty of scientists in their queues who spent part of their childhood in Višnjan. Also, L01 was third in the world in 2018,” according to Korlević.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
