A strong radio burst reaching upto approx 11GHz was observed by the Owens Valley Solar Array at 22h48 UT 29 Mar.

An M1.4 flare peaked at 21h42 UT so the radio burst was probably associated with that.

An M1.9 flare peaked at 22h58 UT.

A space weather inspired pub sign :-)
I check the swpc.noaa website quite often as I like to see what the sun's 'face' looks like, what the auras are up to and I find the solar wind prediction model incredibly soothing... A bit like the BBC shipping forecast.

This is (faux) gold leaf and gold enamel paint. Commissions taken - get in touch if you want it, or something similar.

An X1.1 flare erupted from a new active region on the east limb, peaking at 15h20 UT 28 Mar (not 15h35 UT as previously stated).

After 1.5 hours the XRay flux is still above M-level, but is falling. The flare appears to be a filament eruption.

An R3 radio blackout affected the Caribbean, Central America and northern S America.

10cm, type II and type IV radio emissions and a coronal mass ejection were observed.

This flare marks the end of couple of fairly quiet weeks on the sun!

A large coronal hole is facing Earth, sending a fast stream of solar wind towards us.

But DON'T PANIC! It should be mostly harmless.

The magnetic polarity of the wind from this hole matches Earth's, so at most is likely just to cause a little "buffeting" to our magnetosphere, rather than produce huge spectacular auroral lights down to the equator or knock out electricity grids.

View from my driveway tonight. With these auroral bands, you have a maximum level of energy that is stored in the earths magnetic field. When these maximum levels are reached, it creates a breakup, or otherwise known as a corona. Where the magnetic bands swirl and break apart, releasing the concentrated energy into a more broad, mist like auroral haze.
But for those few minutes of eye watering wonder, it’s quite a good time.

The BGS (British Geological Survey) has issued a rare geomagnetic storm forecast covering the period until midnight UT 23 March. Note that this forecast does not account for the increased activity we saw this afternoon at mid-latitudes, which could have been the storm arriving very early!

BGS: Yesterday afternoon a faint but fast Earth-directed CME was observed. The source was a filament eruption from a central location on the solar disk, associated with a M1 solar flare from a nearby active region.

BGS: Models suggest this may arrive in the first forecast interval (late 22, or early 23). The combination of CME impacts and a high-speed solar wind stream from a coronal hole may result in STORM activity.

BGS: As we are near the equinox, when the Earth is more susceptible to solar activity, it is possible geomagnetic activity could reach STORM G3.
