The Proba-3/ASPIICS paper just dropped on ArXiV! If you like heliophysics, the corona, or cool mission concepts, give it a read. ASPIICS is a coronagraph comprising two spacecraft in formation: a camera and a separate occulter. They're producing amazing images. ☀️🛰️🔭🚀 arxiv.org/abs/2511.01679

This is exactly the reason every mission and scientist should have a wide-open data policy! PUNCH has specific science objectives (looking at the solar wind) – but in the right hands the data can reveal amazing things NOT part of our original science. Giving those hands access is best for all. ☀️🔭🧪
Interstellar comet 3I Atlas from all clear filter data from PUNCH's WFI3 satellite on October 29th. This is the combination of 134 separate images. It's again visible in single frames (moving coming next). Probably visual magnitude ~9.5ish.

David Hathaway and Lisa Upton just released an updated solar cycle prediction. In their words, it's "virtually unchanged since early 2022", an indicator that they're more or less getting it right with empirical prediction. Looks like we're *just* past maximum in the current cycle. ☀️🔭🧪🚀

At the south pole, #SolarOrbiter discovered that the Sun’s magnetic field is currently a mess.
This image from the PHI instrument shows that there are currently different magnetic polarities (north and south) present at the south pole. This happens when the Sun’s magnetic field flips.
