  • We’re currently at solar maximum, which means we’ll be getting the most solar storms for the next few months, then they’ll start tapering off before the next solar maximum around 2035 (it’s roughly an 11 year cycle; they’re not entirely sure why, but this one is a few months early). FWIW, here are my aurora links:

    Dark Site Finder: shows you where there’s historically more or less light pollution, so you can try to find a better viewing area. https://darksitefinder.com/map

    NASA’s Space Weather Center: this is the link to their aurora dashboard page; you can also open up their animated prediction map, to help you figure out if you’re likely to be able to see it in your area. https://www.swpc.noaa.gov/communities/aurora-dashboard-experimental

    Space Weather Live: a site with more data, useful if you know a little about what you’re looking for. It includes a helpful moon-phase indicator, because I always forget that’s something you may need to account for, depending on where you live. https://www.spaceweatherlive.com/en/auroral-activity/.html

    National Weather Service: enter the place you’re thinking of viewing from then, on the results page, click on “hourly forecast” to see how likely it’ll be to have cloud cover, rain, what temperature it’ll be, etc. https://www.weather.gov/

    Aurora Borealis Forecast: has a nice predictor saying things like

    in 1 minutes, the Geomagnetic Activity level (Kp number) will be 8 – at STORM LEVEL! in 9 minutes, the Geomagnetic Activity level (Kp number) will be 3 – Active.

    Those are the actual current numbers. If it’s cold where you are, you don’t necessarily want to be outside all the time (though if you’re in a marginal area, staying outside will help your eyes adjust and you’ll see better). I’m around Kp-7, so I can hang around outside for a few minutes, and when it fades, I can go inside for warmth or at least stop staring at the sky for a bit, then pay attention when it perks back up. They also have a 3-day predictor (less accurate the further out it is). You can also pay for their aurora alert service, if that’s of interest. https://cdn.softservenews.com/

    Google News Alerts: Or you can sign up for a Google News alert for things like “solar storm”, “Corona mass emission”, CME etc - those are the things that create the aurora on earth 24 to 48 hours later. (You can set the frequency of the alerts; I’d suggest once-per-day.) That’ll give you enough time to figure out if the weather and moon are likely to cooperate. As it gets closer, you can check NOAA and SoftServeNews to see if it’ll be viewable in your area, and Dark Site Finder to find the best area to view from (I have different areas, depending on how strong the storm is vs how much time I can afford to be away from home). https://support.google.com/websearch/answer/4815696?hl=en

    Happy aurora hunting!





  • When the air turned orange from the Canadian wildfires last year, I had massive, massive headaches from the smoke. On the recommendation of Wirecutter, I bought a Coway, and my headaches cleared up.

    I’ve been very happy with it. The low and medium settings are quiet, while the high setting is a bit noisy for me. When the wildfires were running, I had it on low or medium all the time and it was fine. Since then, I mostly have it on Eco mode, where it samples the air periodically and kicks on at whatever speed it thinks is necessary. Mostly it just quietly pops on at low speed for dust or pollen or whatever, and I rarely notice that it’s done so. It always kicks in at high speed for a few minutes after I’ve changed the cat’s litter, and once it noticed that the bread was starting to burn in the oven before we did, lol.

    Anyway, I got a Coway based on Wirecutter’s recommendation, and I’ve been very happy with it.

    Edit: I got the 200m, which covers like 1700 square feet.








  • A few years ago, near where my family lived in New Jersey, there was a small newspaper article mentioning that construction on a set of mid-rise condominiums on the Delaware River was being notably delayed, with the vague implication that there was some trouble with financing or construction or something. [To be fair, both of these were true, but for very not-obvious reasons.] But then you start tracing back through the history of the site:

    They had selected the site for the condos because it had been the site of a large flea market from the late 1970s to early 2000s, so all they’d have to do was dig up the parking lots, lay in utilities, and compact the soil to be ready to build. The flea market was there because it was the site of a massive drive-in movie theatre built in the early 1950s, so all they had had to do was put up some cheap buildings that were eventually condemned and torn down. The drive-in movie theatre was there because the land had already been cleared and flattened by the US government, so it was cheap to put in a parking lot and big screen.

    Why had the government so kindly cleared and flattened the ground? Well, the site was right next to a small bridge across the Delaware; on the other side of the bridge was Frankford Arsenal, where they produced munitions during both World Wars. And they had to test the munitions, so they’d drive over the bridge and test them at this site in New Jersey. And it turns out that sometimes they were either high or lazy or careless or something, because sometimes they didn’t bother driving across the bridge, they’d just shell New Jersey from across the river instead.

    The shelling led to a bunch of unexploded ordinance being in extremely unexpected places, until it started showing up eighty years later, when the condo people actually started digging up the ground to lay in their utilities. Of course, the condo association was quietly and casually referencing vague construction delays, because if people knew it was a munitions testing site and they’d recently found a bunch of UXO, no one would buy the condos.

    [Also, while trying to look up details for this comment, I discovered three other cases of UXO in New Jersey in the past couple years. This is all very weird to me.]
