Last night, Kathleen said to me, “I hear the aurora should be good tonight.” I checked the app on my phone that shows me the aurora data. Everything looked pretty good except the Bz value, which was about +17. (For a good show, you want the Bz to be negative. The longer it’s been negative, the better.)
I don’t know about you, but for me, lasagnaEspecially the lasagna Florentine my dad taught me to cook. is the perfect comfort food. When it’s in the house I will happily eat it at every meal till it’s gone.
This time I snapped a photo or two before I devoured it all.
The data looked ridiculous from the outset. There’s one parameter, when you’re consulting the oracle (sorry, the space-weather data), the Bz, that you want to be a negative number. I’ve seen great shows when the Bz was around ‑3 or ‑5. The longer it’s negative, the better.
Yesterday afternoon, every time I checked, the Bz was around ‑15. Crazy.
And the auroral oval looked like this. When it’s yellow, that’s usually a good sign. Red—that much red—is flat-out amazing.
