Aurora Update / Moon Glows Near Jupiter

The auroras we talked about on Monday may still happen, but they’re not exactly on schedule. A moderate G2 storm was expected to get underway today – a day early – beginning late morning or early afternoon, but it’s still pretty quiet out there. Assuming the blast arrives late, that would be a good thing because it would…

Aurora May Drop By Your New Year’s Eve Party

Big sunspot group 2473 cut loose a long-lasting M-class flare earlier today. The explosion produced a fast-moving bubble of plasma directed toward Earth. Plasma, a hot mix of negatively-charged electrons and positively-charged ions (atoms that have lost an electron) may look like a gas but it behaves differently enough to be considered its own state of…

More Aurora? Enough Already!

I’ve been tempted to blog about the northern lights the past two nights. This morning I caved. The past two nights we’ve had weak displays here in Duluth, Minn. Too little to move the needle mostly because they’ve been low and faint. But I find that the more northern lights I see, the more I…
