Astrophysicist Joan Feynman was born #OTD in 1927. She explained the origin of auroras, discovered that coronal mass ejections could be identified by the amount of helium in the solar wind, and elucidated the structure of Earth's magnetosphere. 🧪 🔭 👩‍🔬 ⚛️ Image: Charles Hirshberg

The stretch of road connects NCAR, NOAA, NIST and the University of Colorado-Boulder. Homes to people doing some of the most important research on Earth and its warming climate. I commuted this exact stretch of road on a free bus for 3 years and this video hit me smack in the feels.

I’m at the Solar Dynamics Observatory (SDO) conference this week, discussing science from the spacecraft responsible for most of the space-based Sun images you’ve likely seen! But it’s not all pretty pictures, as SDO continues to produce fantastic science, 15 years since launch.

I wrote for Slate about how a conservative think tank plans to "identify and target" Wikipedia editors who it claims are abusing their position—a dangerous escalation that shifts the fight from debating edits to going after the editors themselves. slate.com/technology/2...

A period of partly-cloudy sky allowed a Sun shot near noon today. The temperature was 31℉, light ground winds, and seeing was generally good -- between clouds! A giant sunspot complex dominates the northern solar hemisphere. #sunspots #sun #solarobserving #solarimaging #astronomy #spaceweather

Here is an eruption over the Sun's northwestern limb observed in SDO/AIA's 171 Å passband a couple of years ago. Found this when I was cleaning an SSD, so I thought I'd share. (Footage courtesy of NASA/SDO and the AIA science team.) ☀️🔭

I have finally dropped the open source for the data of the October 10th 2024 aurora data collection from social media. This can used via CSV/KML/KMZ and coded into whatever data you see fit. A major improvement compared to the Gannon event is every single point now has UTC times.

This diagram I made and uploaded to Wikimedia Commons when I was 16 ended up being used in a peer-reviewed popular-science book. I dislike how the diagram turned out in hindsight, but I am flattered that someone decided it was usable for publication.

A nice Xmas present from ApJ: our solar coronagraph theory paper was accepted on 23-Dec! I just submitted an e-print to the ArXiV. Among other things, we explain the anomalous nearly-achromatic diffraction fringing seen in most modern coronagraph images (it's modified Fraunhofer diffraction). 🔭☀️🎢⚛️

I've found a clever workaround for staring at the sun. I spend all day looking at its light as it reflects off other objects.

Here is how I have been contributing to Wikipedia in 2024. This year I also worked on two research projects at LASP, completed my 2nd and 3rd semesters of college, and started a UROP-funded assistantship. It was a productive year for me personally. #wikipediaYIR

Attention aurora chasers! Have you ever "heard" the aurora? You can actually hear pulsating aurora in power lines like this video (sped up) shows! The exact reason? We don't know! That's why if YOU have a real-time video of pulsating aurora with strange sounds, we're interested! #heliophysics ☀️

Okay, I'll bite. This is simulated data (credit: E. Provornikova; S. Gibson) from the upcoming PUNCH mission. We'll make background-subtracted, polarized images of the solar wind itself, over a 90° wide FOV. Come to our science meeting, PUNCH-6, in February! (punch.space.swri.edu) 🧪⚛️🔭☀️🛰️

☀️Just wanted to share a fun video of Parker Solar Probe diving into its 17th perihelion and what it would see if it had an EUV camera pointed at the Sun. SDO/AIA and Solar Orbiter/FSI had coverage of the full Sun. You can spot the moment Parker is co-rotating with the Sun, where the Sun looks still.

It would be cool to have a bot that posts SWPC alerts here on Bluesky like @/NWSSWPC does on the other site. I would try to make one, but I am so busy at the moment. Would anyone else be interested in something like this? ☀️

New high resolution mosiacs of the full Sun from ESA's Solar Orbiter (PHI and EUI teams), taken in March 2023, are now available! www.esa.int/Science_Expl... Perfect for showing students (or the general public) the large contrast of size scales in heliophysics, from granulation to active regions! 😍

PUNCH's FOV is 90°, centered on the Sun. We'll image the interface between the solar corona and the solar wind that fills the heliosphere (and sweeps over Earth!) starting next spring. That's huge. Here it is in the context of the 2017 total solar eclipse. Not a telescope. punch.space.swri.edu 🧪🔭🛰️
