Wow, insane movement and colors in the aurora over Finland happening now. Check it out on this YouTube stream that is showing real-time video: www.youtube.com/watch?v=W3LK... Additional webcams: theauroraguy.com/pages/webcams #heliophysics ☀️

We (Rachel Howe, Anne-Marie Broomhall, Paul Bushby and me) are hosting a @royalastrosoc.bsky.social discussion meeting in London on 10 Jan, on "Dynamos, Dynamics, and the Solar Cycle at Cycle 25 Maximum. " Abstract deadline is 16 Dec and the link is: docs.google.com/forms/d/e/1F...

Foreground: Time series of sunspot number over the last 200 years.
Background: Two extreme ultraviolet images of the Sun. Left is solar minimum, when there is little large-scale structure. Right is solar maximum, when large, bright active regions are present.

Another truism from the field: Model validation is not forecast verification. Model Validation: use data from time t0, predict state at t0 Forecast Verification: use data at t0, predict state at t0+L, where L = forecast lead time Many models that validate well fail to forecast skillfully

Heads up that SDO imagery will seemingly be unavailable for any unknown amount of time.

Very interesting Veritasium movie about Amelia Earhart's last flight, with some great info about 1930s radio navigation methods, mentioning the frequency-dependent role of the ionosphere. Highly recommended! bsky.app/profile/veri...

Thanks for the heads up. Sometimes there’s hiccups in the databases that can cause that. We don’t download any data - just pull from the native bases and display it. Goddard or one of the other servers may have been down. Let me know if it persists and we’ll look into it here.

Kinda sad that we have to say “if it had an EUV camera…” Note to NASA: include cameras on all of your Helio missions! Look to the Juno mission to see what an off-the-shelf camera can for you mission’s wider appeal.

Happy Sunday from the Sun! ☀️ We have quite a few active regions spread across the disk, but based on complexity, AR3906 has the highest probability for producing a notable flare (25% for M-class & 5% for X-class). For now, we watch and wait!
