"...This was the first targeted dual-polarization radar, multiple-Doppler, and micronet study of the impacts of totality on meteorology and insect behavior...Rapid and substantial changes in the boundary layer and propagation of a prominent radar fine line associated with a posttotality wind shift mechanism different than previously hypothesized were observed. Profound and rapid changes in airborne insect behavior were documented, including descent and then reascent during the minutes immediately surrounding totality, with implications related to solar-related insect navigational mechanisms and behavior."

Continental-scale behavioral response of birds to a total solar eclipse: nature.com/articles/s41598-025 -> Eclipse echoes - groundbreaking study reveals surprising avian vocal patterns during solar eclipse: eurekalert.org/news-releases/1 -> The epic total #SolarEclipse of 2024 caused some birds to stop singing: space.com/stargazing/eclipses/

NatureContinental-scale behavioral response of birds to a total solar eclipse - Scientific ReportsBased on anecdotal evidence and research involving human observation and community science, radar analyses, and acoustical studies, birds are thought to stop singing and engage in nighttime behaviors such as roosting during a total solar eclipse. However, these research methodologies are limited by small sample sizes, potential effects of human observation altering birds’ behaviors, and biases in human-recorded findings. Here we show how a community science network of bioacoustics devices using machine learning revealed a decrease in bird vocalization across North America at sites which experienced more than 99% maximum solar obscuration during the total solar eclipse on April 8, 2024. There was variability between sites in bird vocalization responses to a solar eclipse after controlling for human presence. A widely distributed, connected, and automated passive acoustics monitoring system will allow research into the impact on wildlife of wide spatiotemporal, continental-scale events including wildfires and extreme weather events.

One year ago today I watched the #SolarEclipse in Arkansas. The two total eclipses I've seen have been magnificent to a level that is difficult to describe to those who haven't seen totality.

Here's our photos, experience, and the #weather data I recorded.

Wow, what a fascinating Astronomy Day! The sky was mostly clear in both Bonn and Effelsberg, and our visitors were able to experience the partial solar eclipse (SoFi) on March 29 with their own eyes!

A solar eclipse occurs when the Moon passes between the Earth and the Sun. This only happens during a new moon and when the Moon is aligned with the Sun and Earth. There are three types of solar eclipses:

👉 Total SoFi - when the Sun is completely covered. A total solar eclipse lasts a maximum of 7 minutes and 32 seconds;
👉 Partial SoFi - when only a part of the Sun is covered;
👉 Annular SoFi - when the Moon is too far away and therefore too small to completely cover the Sun.

Since the Moon is 400 times smaller than the Sun and exactly 400 times closer to the Earth, it can completely cover the Sun when viewed from Earth. However, a solar eclipse cannot be observed equally from all places on Earth, but only within a narrow geographic area. But wherever you are, remember: Never look directly at the Sun without proper eye protection! For example, SoFi glasses or a welding helmet with the appropriate protection level are suitable, but not regular sunglasses or binoculars.

In addition to the partially obscured Sun, several sunspots were also visible. The number of sunspots depends on the current phase of the Sun's 11-year activity cycle, which is why they are not always visible.

#SaveTheDate:
📢 The next partial solar eclipse in Germany: August 12, 2026 – over 80% coverage;
📢 The next total solar eclipse visible from Germany: in 2081.
