Space Weather An M6.5 flare peaked at 15h48 UT 08 Oct. A moderate R2 radio blackout affected South and Central America, and southern parts of North America. #spaceweather #g7izu

Space Weather Two incoming CMEs (Coronal Mass Ejections) caused by Earth-facing eruptions are expected to reach Earth on Friday 09 Oct. The first (and weaker) of these may arrive by 04h on the 9th. NOAA has issued a warning of G1-G2 level geomagnetic storm conditions on 09 Oct. #spaceweather

Space Weather A minor G1 geomagnetic storm is continuing. #spaceweather #aurora #g7izu

Space Weather A minor G1 geomagnetic storm is in progress. Aurora may be visible down to upper mid-latitudes before the moon rises (before midnight), assuming you have a clear sky and if the Bz swings negative (it's currently positive at +8nT). Substorms may cause local auroral enhancements.

Space Weather NOAA has issued a G1 geomagnetic storm watch for Friday 02 Oct and Sunday 04 Oct. There is no watch issued for Saturday 03 Oct. #spaceweather #g7izu

Space Weather A large west-side filament eruption that erupted yesterday (28 Sept) has produced a solar storm that will cause us a glancing blow in a few days. Additionally, the fast solar wind from a large trans-equatorial coronal hole will become geo-effective in three to four days.

UK & Ireland Grid Monitor The grid monitor received another update today to fix a fault with Rep of Ireland power cuts reporting. New features also allow mouse over notes, giving details for each power cut on the map, and a new plot showing "customers off by operator".

New Horizons is now *three days away* from shutting off its two heliophysics instruments, simply because NASA has not provided the $2M in funding it had promised to the mission last year or this year. There is no science basis for shutting these off. Our earlier coverage:

NASA’s New Horizons mission may shut down two instruments over lack of funding

UK & Ireland Grid Monitor - UPDATE The grid monitor is had some major updates since the last version.

UK Electricity Grid The UK grid is flirting with a higher than normal operating frequency this morning with frequent short excursions above the normal operational limit of 50.2 Hz, indicating too much generation for the current load.

Space Weather Sudden Storm Commencement: The DST (Disturbance Storm Time Index) spiked to +24nT at 13h UT, suggesting imminent geomagnetic storm conditions, which could follow within hours. The solar wind density is gradually increasing, but is still quite low.

Radio Propagation High pressure across northern Europe is again producing good tropo propagation on VHF. Ship AIS is being received from over 200nm into the Bay of Biscay from Plymouth, UK. #shipais #radiopropagation #amateurradio #g7izu

UK Electricity Imported electricity is currently the largest provider of the UK's energy mix. https://www.tvcomm.co.uk/g7izu/software/

UK & Ireland Electricity A major power cut has hit Northern Ireland. Over 130,000 customers have lost power this morning. #ukgrid #NIE #g7izu Video: https://universeodon.com/@g7izu/117291525820335637

Space Weather A minor G1 geomagnetic storm watch is in effect today. Last night saw very minor auroral activity at high-latitudes. Storm conditions now appear to be subsiding, although the solar wind speed (blue line on the graph) remains steady at around 550km/s. #spaceweather #g7izu

Space Weather A very fast solar wind stream is starting to hit at L1 (and soon the Earth) . This may be the fast wind from two coronal holes that have just passed the solar meridian. #spaceweather #g7izu

Radio Propagation High pressure over Northern Europe is producing tropospheric ducting, extending the range of VHF and UHF signals. My AIS station in Plymouth is receiving ship AIS signals from over 250nm (460km) away across the English Channel and into the Bay of Biscay. #shipais

Space Weather Proton and electron fluxes are rising following a filament eruption.

G7IZU RRD Website - down for maintenance My website at https://tvcomm.co.uk/g7izu is currently down as I work through a PHP upgrade that went south and broke the site. Users may see a message "There has been a critical error on this website."

Space Weather A G1 (minor) geomagnetic storm is continuing. A G2 watch is in effect for tomorrow (09 Sept).

Space Weather The geomagnetic storm strength reached G1 (minor) level at 07h30 UT this morning. Further bursts of substorm activity will continue as this storm progresses, giving further opportunities to see aurora at the higher latitudes. #spaceweather #aurora #g7izu

Space Weather: Geomagnetic Storm Update Geomagnetic activity is continuing to build as a number of CMEs reach Earth. Aurora has been seen at high latitudes.

Space Weather Disturbed geomagnetic conditions are continuing. Significant solar wind dynamic pressure of 30 cm^3 is being recorded at L1, along with a marked negative Bz swing to ~ -12nT.

Space Weather CME arrival: The first CME in a potential series has arrived overnight - somewhat earlier than predicted. IMF Bz is strongly southward and substorms are now hitting polar regions. HF radio will be degraded at high latitude and polar regions - aurora is possible.

Space Weather Incoming Solar Storms: In recent days several active regions on the sun have launched many CMEs (coronal mass ejections). Only a small number of these appear to be Earth-directed. AR4520 launched an M1.0 flare which produced yesterday's high-energy proton storm.

Space Weather Strong proton event just starting #spaceweather #g7izu

GB Grid Monitor: One for the data geeks! You may know that I recently created an energy and environment dashboard that's available to download on Github.

Space Weather An M3.0 flare peaked at 19h21 UT 02 Sep. Type II and IV radio emissions were observed, with a CME being observed in imagery. The flare originated on the east limb so the CME will not be Earth-directed. #spaceweather #g7izu
