Note that the severity of these GICs depends a lot on geography.
I would recommend checking out the NWS and FEMA resources linked below if you are concerned.

Devices not plugged-in should be safe, while those plugged-in might experience voltage spikes/instability as a secondary effect of geomagnetically induced currents (GIC) along long-distance transmission lines. Your devices will effectively be isolated from any direct GIC flow, however.
Geomagnetic storms from CMEs only induce damaging electrical currents in long electrical conductor systems like power transmission lines and oil and gas pipelines. Personal electronics are too small for any appreciable current to form and should be safe even during a severe storm.
This is a photograph made by the Artemis II crew just after the Sun went behind the Moon from their vantage point. The inner Zodiacal Light and outer corona form a diffuse glow around the hidden Sun, from which radiates spikes and a general radial texture whose details constantly change.
The view of the Solar corona the Artemis II Astronauts had just after the Sun went behind the Moon. I have brought out the delicate fan like radial detail of the Sun's corona, whose entire span can be seen during Total Solar Eclipse from Earths surface where the Moon happens to just cover the Sun.
Adding in the COSMO K-COR coronagraph fills in the lower corona which is a crucial region to not only detect CMEs soon after they launch off from the Sun but also understand their rotations and twists as they are steered by magnetic fields before traveling further into space.
The Mauna Loa Solar Observatory site.
New road to MLSO
We’re not foolin’ you! The Mauna Loa Solar Observatory (MLSO) has officially reopened in time to assist NASA’s Artemis II mission with space weather warnings! It has been closed since Mauna Loa’s 2022 eruption blocked the road, making the site accessible only by helicopter for special operations.
It is the MessagEase layout originally released in 2002 for the Palm. It looks like the person in the video is using FlickBoard, an open-source alternative available on Android.

OMB and admins at NSF are selling off NCAR by using a Dear Colleague Letter to solicit buyers.
🚨 A whistleblower says the DCL is a feint and a for-profit company is already set to buy parts of NCAR's space weather program 🤬
Title bar of "Polarization Diagnostics Applied to Coronal Mass Ejeections and the Background Solar Wind", a newly published paper in the journal Solar Physics
<thud>! Another PUNCH paper dropped today! Congratulations to Sarah Gibson on this omnibus theoretical treatment of polarization in solar wind structures. Given the simplicity of the Thomson scattering mechanism, it's pretty amazing how deep the rabbit hole can go. 🧪☀️⚛️🔭🛰️

Unprompted by anything specific… worth noting that WIRED’s ASME award nominated package, “How To Win a Fight,” includes a piece on how to advocate for your trans and nonbinary neighbors:

"60 mm/a (0.075 in/Ms)" is from the wikitext conversion template {{cvt|60|mm/yr}}. The "to units" parameter was left empty, so the template just uses the default conversion for each unit: mm to in and yr to Ms. I do not think that geologists actually use in/Ms.

Yes: Hinode and TRACE. But I do not think SSO is ideal because their orbits regularly pass thru the South Atlantic Anomaly where elevated cosmic ray flux produces noise in the image data. There are also solar imagers in GEO (GOES, SDO), Sun-Earth L1 (SOHO, Aditya-L1), and heliocentric (PSP, STEREO).
Yes. Satellites monitor solar activity 24/7. NOAA's GOES series of satellites in particular. There is also a global network of ground-based solar telescopes (GONG).
Solar cycle 25 is expected to start winding down, and solar activity is pretty low right now. There were a few large flares at the beginning of the month with the third largest flare of this cycle (~11 years) on Feb 1st iirc.
We do not have this problem in solar astronomy
The full circle disk image of the sun in hydrogen-alpha light (false color applied) depicts our local star with flame-like prominences at multiple locations around the rim -- the filament/prominence -- filaprom -- feature is at about the fout o'clock position on the disk.
Here's a full-disk view of Sun as it appeared yesterday. We were so excited capturing the filaprom that we let the full disk view go. This really shows off the extraordinary prominence activity that was going on midday, February 16! #sun #astronomy #solarobserving

Farewell to Active Region 4366 -- Giant sunspot complex seen in Sun's northwest. The region continues to issue flares but is showing signs of decay. Soon the sunspot will disappear over the Solar limb. Sky was clear, and winds were light, but seeing was not good. We take what we can get! #sunspots

It's good to talk about your love for Wikipedia. It's good to donate. But I firmly believe that it's even better to become an editor. Create an account. Make an edit (don't worry, you can't break things). Visit the Teahouse. Not necessarily in that order.

The atomic ensemble time scale at the NIST Boulder campus has failed.
The second step (deconvolution) helps further reduce blurring, but subsequent processing appears to be cosmetic. For example, the brightness of the solar disk appears to have been inverted here; brightness should decrease with distance from center disk, and the dark splotches should appear bright.
Many of the individual frames will be heavily blurred/distorted due to turbulence in the Earth's atmosphere, so the idea of the first step ("lucky imaging") is to average over the frames that appear the least blurred. This produces a more accurate and better looking image.
A sunspot group over about an hour on 2022-09-03. It starts showing the photosphere on the "blue side" (shorter wavelength) of H-alpha, then shifts into H-alpha and finally goes back to the photosphere on the "red side" (longer wavelength).
