@ai6yr@m.ai6yr.org Does that make me a historical artifact too? I was born in '63. Maybe only if I was wedged in a rock for 50 years... 🤔

Space Weather Ops dashboard
The dashboard on my site has been updated so that it's more responsive on mobile displays.
Today I also made a number of refinements, including the addition of sending alerts to a Pushover account (click the Push button above the Event Log panel). A free Pushover account is needed.
The number of parameters that can trigger alerts has also been expanded.

A strong G3 geomagnetic storm is in progress. Aurora may be visible at lower mid-latitudes.
Aurora is being reported by amateur radio operators down to ~52°N over Europe.

Another view of the X1.5 flare, this time with SDO's AIA171 filter. This highlights the magnetic "slinky" expanding from the eruption site.

I've done a final update (for the time-being!) on the Space Weather Ops dashboard.
Numerous fixes for a number of coding errors! Audio and Pushover alerts have been worked on so that alert "flooding" is avoided during major events. I'm hoping that the incoming solar storm will give it a thorough test!

My Space Weather Ops page has been worked on today and had a number of changes bug fixes.
One big update is that there are now double the number of base regions available in the Path Estimator (22 instead of the original 11). There are also new columns for the propagation modes which are active on each path, although I suspect this feature still has some errors, particularly around TEP path estimation.
A small but important change is that the FLARE chip on the very top line now shows the maximum X-ray flux in the last hour instead of the live value as seen in the box below it, so if you've glanced away you can still see the highest flux value reached.
A fault on the D-Rap map background was fixed, along with numerous backend fixes.
Radio Propagation
It's the evening in Australia and Japan, early morning in Western Europe. This is what the 10m band is doing right now, based upon DX CLuster reports.
Radio propagation visualised!

A G2 geomagnetic storm watch is in effect for 17 & 18 April.
Earth will be coming under the influence of a fast solar wind this large coronal hole, which is now facing towards us.
Strong aurora may combine with meteors from the annual Lyrids meteor shower, which peaks on 22 April, making for some stunning phot opportunities!

A ridge of high pressure pushing down the North Sea is creating ideal conditions for some strong tropospheric propagation.

An M3.5 flare peaked at 18h15 UT 02 April. A minor R1 radio blackout affected the Atlantic and Americas.
A G2 geomagnetic storm is in progress, although auroral activity has now calmed down with a Kp of 1-2 being observed in the last few minutes.
The solar wind speed has nearly doubled in 24 hours and just now peaked briefly to 702km/s. We should now be feeling the effects of the fast solar wind coming from the coronal hole, that passed the meridian a couple of days ago. Bz is still negative.

The CME launched by this morning's X1.5 flare is likely to give Earth a glancing blow late on 31 March or early 01 April.

Radio Propagation
While we wait for the sporadic-E season to get going properly, here's a demonstration fly-through of this afternoon's global 10m to 2m band propagation, recorded live from amateur radio DX Cluster data with a five-minute cadence, at 17h07 UT 28 March.
The yellow lines denote 10m contacts. As you can see, there's not much going on above the 10m band at the time of the recording. All the lower bands have been supressed so as to make 10m clearer.
The number of hops and reflection locations any particular signal path makes is estimated and not real, but is based upon real factors such as ionosphere height, propagation mode and the MUF. Different frequencies reach different heights, as future videos will show.

Geomagnetic conditions have calmed and are now at G1 levels.
Solar wind speed is is just under 700km/s with the Bz between 0 and -5nT.

Despite a very strong AE (auroral electrojet) and a solar wind speed of 711km/s, the IMF is now in positive territory, meaning very little or no aurora for the time being 😠

Although a CME shock was detected at L1, we now appear to be brushing the edge of the CME "sheath" and are not fully within the structure.
The full force of the CME passed well to the southeast of Earth during the past 24 hours. The two "legs" of the structure are slowly pushing sideways and one is starting to interact with Earth's magnetosphere. It may take a few more hours for us to see the full geomagnetic effects.
The earlier mentioned coronal hole just to the west of the flare location is retraining the westward extent of the CME. We'll see the fast solar wind from the coronal hole in a couple of days.

Region AR4409 has been busy popping off one moderate and two minor flares in the past 12 hours.
Peak times on 04 April:
M7.5 01h07 UT R2 HF blackout
M1.7 07h56 UT R1 HF blackout
M1.3 12h10 UT R1 HF blackout
On CMEs were observed.

Radio propagation visualised in 3D! Two examples of auroral propagation on the 2m band caught on my Ionospheric Path Monitor just now.

A small eruption from AR4403 at 22h20 UT 01 March caused this small flare and CME. An even smaller eruption from AR4407 to the east is also visible in this video from NASA/SDO AIA304. Neither flare exceeded C5.8.
A type II radio emission was detected, confirming a CME that went northwards.
Meanwhile at Earth, we're still in the ragged edge of the previous CME which started affecting us yesterday. Geomagnetic conditions have fluctuated overnight with brief G1-G2 conditions being observed. Minor aurora affected higher latitudes.

Radio Propagation
The VHF/UHF FT8 Activity Contest kicked off at 18h UT. See the contesters on this flythrough aver Europe. 2m band contacts are the red lines, and as the contacts are mostly tropospheric, the signals are hugging the surface of the planet within a few km.
It's fitting that Dave, G7RAU (and author of LiveMUF) is one of the contacts seen in this video (at the bottom end of Cornwall).

@scott It requires LiveMUF on the same machine, collecting spots from a number of DX clusters. Data is saved to an SQLite database. A small Python client feeds the spots from the database to the html front-end which displays the maps. Any hard-end number crunching and display calculations are done in the web browser! Keyframes can be stored and recalled to create the fly-through paths.

NASA & ESA's Artemis 2 crew will be fighting a slight crosswind as it approaches reentry.
The solar wind speed has increased to around 600km/s, but the density if very low, so it's not actually any problem.
A G1 geomagnetic storm watch is in effect until the end of 11 April (UT).
