What sort of effects does this have in reality please?
Yesterday (Feb 23rd here in Australia) I was back at a job I'd done some RTK work on in Decemebr last year and i had some rather mixed results on points I checked to.
Both time conditions were 'ideal'. Low PDOP, 8+ satellites (not Glonass) and clear skys out in the middle of a farming area (no trees).
I set up on same base and proceded from there over about 2.5km radius.
I'd let it take sets of 5 observations and then mean those.
Measurements on some varied by 50mm which was not what I'd come to expect.
Others were 15-20mm which I could wear over 2km.
I did check some lines with total station and am still working through those of yesterday but Dec 12th ones were about cm or less which I was happy with.
I use Field Genius software.
I read this on SpaceWeather
SOLAR TSUNAMI: Tangled magnetic fields on the sun's NW limb erupted today, February 23th, producing a solar tsunami. You can see the shadowy yet powerful wave rippling away from the blast site in this move from the Solar Dynamics Observatory:
Hi Richard
This is a useful page to check the 'space weather', not a forecast but handy for an 'aftercast'.

The solar storm you mentioned hasn't reached here yet, it's usually 18-24 hours before the earth is affected. Fairly quiet on the 23rd as well. One of these solar bursts doesn't always mean we experience disruption either, depending on the polarity it can be deflected away rather than flowing into our magnetic field.
Checked the bubbles on your base and rover?
The Worst Interference I Have Seen
Was with satellites that were between me and the sun. Residuals out the wazoo. Removing those satelites allowed a close solution. Fortunately I have not experienced the full sky electrostatic mess up that is possible.
Mess up can be random and irregular, best advice for RTK, do everything 3 times, check into multiple control hourly and then redo the worst field points.

The Worst Interference I Have Seen
yes bubbles OK thanks.
I was aware of suns shenanigans but never understood when and where and how.
I was concerned the software could influence the results (regardless of what the sun is spitting out) but seeing I had same settings both days i would not assume (hope) that would misbehave.
Back in the good old days one could read and reread and then double measure for check and be happy to go home with a result.
Never felt entirely comfortable with devices that spit out figures electronically.
But then I never doubt my total station 😉
