Do Something Region

Today’s Sun – 5th June 2025

There are currently four sunspot regions doing their thing on the Sun:

4105, 4106, 4100 (yep, the one that gave us those epic Auroras a few nights back), and 4099.

If you’re hoping for another round of magical sky lights, here’s the deal:

For a CME (Coronal Mass Ejection) to be Earth-directed, it needs to come from the centre stage of the Sun — the “Earth-facing zone.” Think of it like a game of solar darts: the bullseye is the middle of the Sun’s face, and that’s where flares have the best shot at hitting Earth. If everything else lines up — like fast solar wind and a south-pointing magnetic field (a grumpy Bz) — boom, we might get auroras!

What’s a Sunspot Region Anyway?

A sunspot region (or active region) is basically a cosmic tantrum happening on the Sun’s surface. It’s where intense magnetic fields twist and tangle so much, they mess with the surface temperature, making parts of it cooler and look darker — like bruises on the Sun’s skin.

These sunspots are also where all the action starts — flares, CMEs, and all the wild solar drama.

But Wait… Why Is East on the Left?

Ah yes, the Sun playing mind games again.

East and west on solar images are flipped compared to Earth maps — but don’t blame NASA. It’s all about perspective.

When we look at the Sun, we’re seeing it face-on. So just like when you look at a friend, their left is your right, and vice versa.

So:

When sunspots first show up, they appear on the left of the image (that’s called solar east).

And when they rotate out of view, they exit stage right (a.k.a. solar west).
