Goes 19 Outage - Update Space weather data and weather images are flowing again from Goes 19 following an outage lasting nearly 24 hours. Xray flux data restarted at around 16h UT today. #spaceweather #noaa #goes19 #g7izu

Goes-18 Outage This message from NOAA regarding Goes-19 (aka Goes East)

Climate report: The State of UK Climate in 2025 "Climate extremes are becoming the new 'normal' for the UK." "The climate of the 20th Century has now gone." Long read:

Ship AIS Decoding I've been trying to decode and upload Ship AIS messages to seven or eight ship tracking websites for a number of years, but have always had issues with AIS aggregators such as AIS Dispatcher crashing many times per day, requiring manual restarts and a lot of frustration. This is p

Radio Propagation FM Band 2 is open between Scandinavia and UK/Ireland this evening via sporadic-E. #radiopropagation #fmdx #g7izu

Space Weather The fast solar wind from a trans-equatorial coronal hole is now hitting Earth. The speed has been increasing most of today and is now at around 600km/s.

Space Weather The geomagnetic storm of the last few days has subsided and HF radio conditions are now recovering. GPS disruption due to scintillation has also reduced.

Space Weather Further to the X1.3 flare, a 10cm radio burst was recorded with a peak flux of 890sfu lasting seven minutes. A type II radio emission was detected with an estimated velocity of 2,714 km/s, which is incredibly fast, and may be an error in detection.

Space Weather An X1.3 flare peaked at 20h41 UT 04 July. A strong R3 radio blackout is affecting North and Central America and the eastern Pacific Ocean. #spaceweather #g7izu

Space Weather STRONG G3 GEOMAGNETIC STORM in progress. For the first time in a long time we're being treated to the "core" of a coronal mass ejection. Disturbed conditions will continue for many hours.

Space Weather Geomagnetic Activity: A G2 geomagnetic storm is in progress. #spaceweather #aurora #g6izu

Space Weather An M6.3 flare peaked at 18h59 UT. A moderate R2 radio blackout briefly affected North and Central America. This is the second large flare within an hour. #spaceweather #g7izu

Space Weather An M6.7 solar flare peaked at 18h10 UT 03 July. A 10cm radio burst was detected, suggesting the release of another coronal mass ejection.

Space Weather Still waiting for a CME arrival at Earth. This one is taking its time! #spaceweather #g7izu

Space Weather CME "Sudden Impulse" Detected The first CME in a train of CMEs is almost upon us.

Space Weather We're in for a couple of days of solar storms, starting tomorrow (03 June) as the CME from the X1.1 flare on the 30th and several smaller CMEs reach us.

Space Weather The sun is unsettled today following from yesterday's X1.1 flare. This morning the X-ray flux has risen above M-level on no less than seven... no, eight (and counting) occasions.

Space Weather Major X flare in progress, peaking at X1.1. A strong R3 radio blackout is affecting the eastern Pacific and North American regions. The flare is now reducing. Standby for updates. #spaceweather #g7izu

Space Weather An M5.7 solar flare peaked at 12h51 UT 30 June. A moderate R2 radio blackout is affecting Europe and North Atlantic regions, impacting trans-Atlantic HF radio propagation. The radio bands will recover over the next hour or so. #spaceweather #g7izu

Terrestrial Weather Thunderheads are now visible on the cameras. #weather #g7izu

Terrestrial Weather The heat before the storm... Still bright sunshine in Plymouth and 30°C. The initial storms look like they'll be heading a bit west of me into Cornwall, but the following ones may be drifting more eastwards. #weather #g7izu

Terrestrial Weather Supercell thunderstorms are now en-route from Brittany across the channel to south-west England, ETA at Plymouth roughly 16h UT. #weather #g7izu

Terrestrial Weather Convective (thunderstorm) outlook for the UK and Ireland until 06h Friday. Most of the UK and Ireland are within the black "severe" boundary. #weather #g7izu

Space Weather The fast solar wind from a coronal hole is hitting Earth. A minor G1 geomagnetic storm hit overnight and is in progress. The solar wind speed is 650km/s. DST ring current is strongly negative but the Bz is neutral. #spaceweather #g7izu

Radio Propagation How to spot a sporadic-E signal in the melee of tropo signals? Look for the rapid signal fading. This is Radio marcia in Mallorca again. #radiopropagation #amateurradio #g7izu

Radio Propagation Under the heat dome of Europe, very good tropospheric propagation across the north and north-west. Here, the FM band is jammed with tropo signals from France. The capture shows my full FM band. #radiopropagation #amateurradio #g7izu

Space Weather A trans-equatorial coronal hole is facing Earth, along with another coronal hole in the northern hemisphere. An increase in the solar wind speed should be reaching us in a few days, causing an uptick in geomagnetic activity. #spaceweather #g7izu

Space Weather An approx. M7.0 flare peaked at 19h29 UT 21 June. A moderate R2 radio blackout affected North and Central America. A type II radio emission was also detected, indicating the possible release of a CME. #spaceweather #g7izu

Space Weather Our sun is very quiet this week. The solar wind speed has dropped from 450 to ~350km/s today. The F10.7 solar flux is low at 111sfu, meaning poorer HF radio propagation due to less ionization of the ionosphere.

Space Weather Ops Another update today for the Space Weather Ops dashboard. A couple of important changes: The path estimator matrix has been overhauled to reduce the amount of chaotic flashing. Please check the colour key at the bottom of the panel for the changed indicator states.
