@olivertraldi Some books fall flat on the water and sink like a stone and don't need a review. And some are bad and by prominent people and need substantive critique. Others mostly need a review that gives a reader enough perspective to decide to read them

The ozone hole continues to heal.

Each year, it reaches an annual max extent. This year's extent was the seventh smallest since the ozone layer began recovery after the adoption of an international agreement phasing out use of ozone-depleting chemicals.

Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground. However — when intense enough — they can disturb the atmosphere in the layer where GPS & communications signals travel.

@HPS_Vanessa I am on bsky too, but stay on x mainly for the government agencies and scientific professional societies that seem uninterested in moving. I skip the other posts

@rebecca_charbon Now I'm glad(der) now to have you there!

@CSRDay And my first thought: Newton was already dead for a year.

@darwinsbulldog @ProfTyndall Say it ain't so! It's true. Herschel's handwriting is a challenge. The letters of Brewster that I have looked at were even worse: bumps on a series of continuous lines.

@inenoha In my encyclopedia, Aristotle is cited more times than, say, Charles Lyell. The encyclopedia is about the history of the earth sciences.

MINOR RADIATION STORM IN PROGRESS: The GOES 10 MeV radiation threshold has been passed which puts us in an S1 radiation storm. The main effect is to radio communications in the polar regions and may divert some transpolar flights.

@BartlettAstro @adsabs @SciXCommunity I like the video! Simple and to the point

If you are a historian of earth and space science and you don't know the Astrophysics Data System, let me introduce you. It's an invaluable way to explore a vast literature. And change is always afoot.

[SAO/NASA Astrophysics Data System (ADS) @adsabs]

What should Astrophysics Data System users know about the NASA SciX expansion of the ADS digital library? Hear more from @BartlettAstro & check out our new blog post (https://t.co/ZlixmConE0) to learn how user input is informing NASA SciX development.

@inenoha I also wish I could write every book that is in my head, but that is not possible. And I like enjoying family and living. All work and no play is not healthy.

Happy #SunDay! This week’s space weather report includes:
· 4 X-class flares
· 3 M-class flares
· 20 coronal mass ejections
· 0 geomagnetic storms

NASA’s Solar Dynamics Observatory shows the Sun’s activity – check out the X-class flares at 0:07, 2:38, 2:47, and 3:04!
