Aurorae in Chinese Annals

22 April 2022

Marinus van der Sluijs, who has written some interesting articles for SIS journals, is in the science news this week. In collaboration with Hisashi Hayakawa from Japan, he has published a research paper in Advances in Space Research, on a reference to aurora in the Bamboo Annals [Zhushu Zhao].  See https://phys.org/news/2022-04-earliest-candidate-aurora-chinese-annals.html … the reference dates to the Zhou dynasty, somewhere between 977 and 957BC. They suggested it reflects a major geomagnetic storm. Interestingly, it is known the north magnetic pole was inclined towards the east in the mid 10th century – around 15 degrees closer to China than it is now. Therefore, the auroral oval could have been visible to observers in central China during significant episodes of magnetic disturbance.

At https://www.sciencedaily.com/releases/2022/04/220414125109.htm … nova outbursts are apparently a source of cosmic rays, such as gamma rays. Novas, and Supernovas, are a source of cosmic radiation in the universe. They consist mostly of protons rich in energy.

At https://phys.org/news/2022-04-earth-magnetosphere-laboratory.html … a new bit of research has homed in on what they call mini-magnetospheres, the sort that might be engaged in a laboratory. Apparently, small functioning magnetosphere exist on comets, and at certain locations on the Moon.

William also sent in a link to https://www.yahoo.com/entertainment/bizarre-supernova-exploding-wrong-direction-130200616.html … a bizarre supernova. It explodes in the wrong direction. This one is not behaving in a predictable fashion. Or how mainstream theorise it should behave.
