Behold the atmospheric river rolling into California today.. a firehose of moisture wrapped into the rotation of an extratropical cyclone. 🌀🌧️🌧️🌧️

Katla is definitely curious about this object, but she does not yet understand the implications for what is to come...

🚨 EXPLODING WHALE DAY🚨
November 12, 1970:
A 40 ton whale carcass lays, rotting, on an Oregon beach.
A crowd has gathered to watch the whale carcass be dynamited to dispose of it.
HILARITY*. ENSUES.
*”blubber snowstorm”
REMASTERED VIDEO!

We have upgraded our geomagnetic forecast today (12 November 2025) to the highest intensity level amid an ongoing solar storm.
Current predictions suggest that the activity will result in potentially the largest solar storm to hit our planet in over two decades.

Seeing some beautiful photos of aurorae tonight, so here's a reminder that other planets get them, too!
This is Saturn, with aurorae visible at both poles in this UV image from Hubble's Space Telescope Imaging Spectrograph, taken in October 1997 when the planet was 1.3 billion km away.

Aurora color guide! What creates the different shades?
Different atoms getting "excited" at different altitudes
The bright reds are a sign of a particularly intense event

Weird that we have a planet-wide magnetic defense system that self activates when the sun decides to attack but it is very pretty

If you have a very low-latitude aurora observation from tonight, please record your exact time and rough location and DO NOT DELETE your photo. These observations will be important for scientific research of this event.
Comment below if you have a low-latitude aurora sighting.

Looking through the Mt. Wilson webcams, and aurora Los Angeles extremely confirmed (for earlier this evening)!
(But these colors are not clearly there on the webcam now, so it might be over here, sadly.)

There’s been a lot of discussion about “weak and compliant faults” at this workshop, and I feel like that’s also a good term for certain senators…

The college-level committee ranked my application merely "meritorious," which means that, unless the number of available sabbaticals changes, I won't be getting one this time.
So that also means I will have worked here for at least 11 years by the time I do get one.

My sabbatical application is due today. Maybe I'll finally get one this time!
(I've worked here since the the beginning of 2016 and have not had a sabbatical yet, even though I have applied for one before.)

This #Halloween, we couldn't think of much that's more terrifying than not knowing what to do when an #earthquake strikes.
...But then we thought of this situation 😱

4 days of seismic records from a seismic station in Jamaica shows Hurricane Melissa roaring towards the island.
Hurricanes increase the amplitude of ocean waves which beat on the coast and sea floor. These produce Rayleigh waves that can be seen as increasingly thick “wiggles” in seismic records 🧪
