Solar storms can cause power blackouts, interrupt communication, and even make satellites fall to Earth prematurely. Scientists study space weather to predict it: buff.ly/npSaKFa

We had a blast answering questions about the solar wind and solar storms as part of @us.theconversation.com's Curious Kids series 🛰️ 🌞 theconversation.com/what-are-sol...

Our new paper is published! 🥳Observational Constraints on the Radial Evolution of O6+ Temperature and Differential Flow in the Inner Heliosphere using @science.esa.int Solar Orbiter mission doi.org/10.3847/2041...

NASA’s Parker Solar Probe Snaps Closest-Ever Images to Sun Newly released images - taken closer to the Sun than we’ve ever been before - are helping scientists better understand the Sun’s influence across the solar system, including events that can affect Earth. 🧪🔭 science.nasa.gov/science-rese...

Visiting MSSL today, had a fantastic time chatting with everyone!

With the excitement of recent observations from NASA's @punch-mission.bsky.social, a collated image showing the synergy it could have with a proposed NASA SMEX mission, EUV CME and Coronal Connectivity Observatory (ECCCO), in the inner most corona!! #Teamwork Credit: Kathy Reeves & PUNCH team

Amazing!! Go PUNCH!

This is just the beginning! ☀️

Please consider submitting to our session at ESWW 🌞 🛰️🚀 🗣️ Call for abstracts for ESWW 2025: CD8 - The Vigil Mission: Advancing Space Weather Operations & Science. 📆 Deadline for oral presentations is 15 May 2025 (5 Sep for posters). 👉 esww.aeronomie.be Go Vigil! 🛰️

This is NOT good. Still wrapping my head around what the fallout of this will be. But definitely NOT GOOD. Check in with your NSF Fed friends, y'all. They might be getting bad news right now. www.science.org/content/arti... #savescience #savensf #WeekOfAction #advocacy #NSF #NSFfunded

Shifting perspective on the Sun provided by @esa.int Solar Orbiter on its inclined orbit. Low-latency images from the EUI telescope from around perihelion last month to now. 😍

NASA just released the first-light images from the PUNCH mission! The WFI images are spectacular. More images will be forthcoming on the PUNCH website soon. 🔭🛰️☀️

My PhD student Aisling O'Hare has published her first paper studying the impact of QPPs in solar flare emission on Earth's atmosphere. The ionosphere is much more sensitive to small changes in EUV irradiance than previously believed as measured by changes in total electron content. 👏

We have published an update to our #solarstorm catalog today, now with 1901 in situ observed events. Solar ☀️ activity in 2024 was really strong, adding another 192 events measured at @esa.int Solar Orbiter, NASA Parker Solar Probe and other missions, with 50 events at 🌍. helioforecast.space/icmecat

We just launched a mission account for PUNCH: @punch-mission.bsky.social. That account will be a good source for mission updates and science "nuggets" as they happen. Click through and follow it if you like. 🧪🛰️☀️🔭 punch.space.swri.edu

ESA @esa.int Solar Orbiter is diving towards the Sun and should be crossing the heliospheric current sheet very soon; which is anchored by a nested active region! Later this month we will try to make observations of fast solar wind sources, with coronal hole 3 looking like a promising candidate!

NASA is facing enormous cuts, half of its science budget, under DOGE. The impacts on the agency could be devastating, possibly including the cancellation of entire missions such as Hubble, Perseverance, and Voyager. Story by me in New Scientist (free to read) www.newscientist.com/article/2472...

An exciting opportunity here to build a new data assimilation scheme for the unique (but underused) heliospheric imager data. This could be huge for space-weather forecasting.

The Planetary Society strongly opposes the sudden, indiscriminate dismissal of more than 1,000 scientists, engineers, and explorers at NASA — the largest involuntary workforce reduction since the end of the Apollo program. Read more on our stance. ⬇️

New paper day! Savita Mathur and collaborators expand the sample of Kepler stars with measured photometric variability index (S_ph) and investigate the dependence on stellar Rossby number (the ratio of convection and rotation timescales). Paper here:https://arxiv.org/abs/2502.10109 (1/4)

☀️ Happy to share a new paper discussing coverage of different state variables and the magnetic field from the Sun to the heliosphere: arxiv.org/abs/2502.06036. Here are figures for density diagnostics. It is really striking how close #ParkerSolarProbe gets to the Sun.

💫🎉 Behind every successful ESA space mission, there's a woman. Behind the ESA & NASA Solar Orbiter mission, there are more than a hundred of them! Join us in celebrating them today, on international day of women and girls in science! #WomenInScience #WomenInSTEM 🔭🧪 www.esa.int/ESA_Multimed...

Including many former and current scientists and engineers from #MPSGoettingen! Thanks for your contributions to the mission! ☀️🔭 #SolarOrbiter #WomenInScience #WomenInSTEM

Open Call for Proposals for International Teams in the Space & Earth Sciences is released www.issibern.ch/call-for-pro...

Not sure what kool-aid people are drinking on DEI. As a manager of scientists I have found diversity — of background, approach, culture, gender, and other axes — to be essential to healthy and productive group work. The more angles a team can take on a challenge, the better they do at it. 🧪

☀️Happy to share our manuscript distinguishing the acceleration mechanisms between the conventional slow and Alfvénic slow solar wind has been accepted for publication! 🥳 Arxiv link to follow.

Early morning interview with @cnn.com on #ParkerSolarProbe's closest approach 🛰️☀️ I'm so happy to be part of this incredible mission!!

Just finished up a live interview on #ParkerSolarProbe’s closest approach on CBCNews @cbcnews-rss.bsky.social ☀️ I’m so excited about all the news coverage about the Sun!!

“This holiday season is not immune to @NASA barging in: On December 24, the agency’s Parker Solar Probe will make its closest approach to the ☀️.” #tohellandback #NASAHatesHolidays Thanks to Nadia Drake for helping me improve my writing this year! www.washingtonpost.com/opinions/202...

☀️Got to stand next to a life-sized version of #ParkerSolarProbe last week at AGU! It’s home will be the Air and Space museum for everyone to enjoy 🛰️🚀🌞

50 Years Ago: Launch of Helios 1 to Explore the Sun www.nasa.gov/missions/hel...

Kicking off this Bluesky thing with a fresh new paper! We analysed and modelled a CME that impacted four spacecraft spread out between ~0.4 and 1 au from the Sun—we investigated radial evolution and whether measurements at an inner probe improve predictions at an outer one: doi.org/10.1093/mnra...

🥳☀️Happy to share our recent paper on the transition between slow and fast solar wind led by Ben Alterman: arxiv.org/pdf/2411.18984

Job alert! Postdoctoral Fellowship in sunspot classification and solar flare forecasting using machine learning @DIASAstronomy. Deadline is December 5. www.dias.ie/postdoctoral...

☀️This year's Total Solar Eclipse occurred around Parker Solar Probe and Solar Orbiter perihelion periods, making this timeframe ideal for capturing a multi-point, -perspective view of the corona and outflowing solar wind. I'll be discussing the ongoing work at AGU!! #SolarOrbiter #ParkerSolarProbe

Really proud of this work (my first time being fully responsible), where I show how the repeated emergence of solar active regions near one another can significantly inhibit the evolution of the coronal magnetic field. (1/3) Published in A&A here: www.aanda.org/articles/aa/...

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...

☀️Preparation for AGU fall meeting has begun! I’m very excited to be presenting the coordinated solar eclipse observations from ground, air, and spaced based instruments!! 🌑🌞

☀️Just wanted to share a paper that was just published by a student, Syed Ayaz, on kinetic Alfven waves in the corona. Important for understanding how plasmas is heated and accelerated from the Sun: www.nature.com/articles/s41...

☀️From ESA, full sun views of the Sun's sunspots, magnetic field, and plasma from Solar Orbiter PHI and EUI: www.esa.int/Science_Expl...

☀️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.
