Geomagnetic activity has increased to a G1 storm (Kp5) due to a phase of negative Bz. This is expected to persist for a while before subsiding to quiet to unsettled (Kp2-3) on Tuesday. The M-flare risk is currently 5%. Conditions will be partly quite favorable tomorrow. #spaceweather #hamradio #hamr
Strong solar winds from a coronal hole will persist for a while longer on Monday but will gradually subside. Geomagnetic activity is expected to be mostly unsettled to active (Kp 3-4). Solar flux is rising slightly (~110 units), and the risk of M-class flares is 10-15%. #spaceweather #hamradio #hamr

The solar wind speed is slightly elevated (~500 km/s) as a fast solar wind is currently arriving from a coronal hole. Geomagnetic activity is expected to be initially unsettled to active (Kp 3–4), before developing into a G1/G2 geomagnetic storm. Solar activity is low. #spaceweather #hamradio #hamr
Geomagnetic activity will initially be very quiet (Kp 0–1) before rising to active to stormy levels (Kp 4–5) late in the evening due to a high-speed stream (HSS) from a coronal hole, with stormier phases (Kp 6–7) possible at times. The risk of an M-class flare is 25%. #spaceweather #hamradio #hamr
Bluesky has been struggling with an outage since Thursday morning. It is unclear whether Bluesky has already identified the underlying issues and when they will be finally resolved. No current information on the status can be found at the moment. I'm very sorry abt. this inconveniance. Tom DF5JL
Magnetic Storm Warning — A large hole has formed in the Sun’s atmosphere, pointing directly toward Earth. Fast solar wind is expected to arrive during the night of April 17–18 (UTC) and may trigger G2-class (Kp 6) geomagnetic storms. Credit: SDO/AIA #spaceweather #hamradio #hamr
Geomagnetic activity is quiet to active (Kp 0–3). Solar activity is also expected to remain at a low level (M-flare risk 30%). However, geomagnetic conditions will become stormy from April 17 to 18 (UTC). Until then, propagation conditions will be fair to good. #spaceweather #hamradio #hamr
The solar wind speed is currently at background levels. Geomagnetic activity is expected to be mostly quiet, though periods of unrest are possible. Solar activity is very low, with a 10% risk of M-class flares. SFI 101, the MUF3000 is just barely reaching the 12m band. #spaceweather #hamradio #hamr
The solar wind has weakened. Geomagnetic activity is expected to be mostly calm, though some periods of activity are possible (Kp 1–3). Solar activity will remain at a low level; isolated M-class flares are not very likely (10%). Will the SFI break the 100 mark today? #spaceweather #hamradio #hamr
Once again, our forecast (max. MUF ~21 MHz) turned out to be correct today. Why? We evaluate more than a dozen different sources daily, incl. NASA, NOAA, WDC Kyoto, UK Met Office, KMI, GFZ, IAP and many others. So thank you for your interest. (Credit: propquest.co.uk) #spaceweather #hamradio #hamr
Solar activity remains low; M-class flares are unlikely. The solar wind is gradually subsiding. Geomagnetic activity will be mostly quiet, with occasional periods of activity (Kp 1–3). Conditions are good on the lower/mid bands, fair to good on 17/15m. Max. MUF ~21 MHz. #spaceweather #hamradio #hamr
Geomagnetic activity is mostly moderate to active (Kp 3–4), but the activity will subside on Sunday. Solar activity is low. The cutoff frequency for 3000 km paths will hover around the 28 MHz mark during the day but will often remain stable in the 21 to 24 MHz range. #spaceweather #hamradio #hamr
Geomagnetic activity is mostly quiet to unsettled (Kp 2–3) with occasional active to stormy intervals (Kp 3–5). Solar flux <100 keeps 20m and 17m stably open all day, 15m good at midday, 10m likely marginal. 40/80m may show stronger fading (QSB) and increased noise. #spaceweather #hamradio #hamr
Solar activity is low (M 35%), geomagnetic activity will initially be mostly quiet to unsettled (Kp 1–3). However, strong solar winds from a coronal hole may arrive later and trigger an active to stormy phase (Kp 4–5). Till than, conditions are fair to good (15/17/20m). #spaceweather #hamradio #hamr
During the day the solar flux of ~105 units is promising good DX on 15/12m. Starting in the evening, 40m becomes the global DX band; 160/80m promising good conditions by quiet geomagnetic activity (Kp1-2). Disturbances due to coronal holes are not forecast until Friday. #spaceweather #hamradio #hamr
#spaceweather #hamradio #hamr Geomagnetic activity continues to subside and will range from quiet to unsettled (Kp 2–3). Solar activity is low, the solar flux index will be around 115 units. 15 to 20 m are opening reliably, with the 30/40 m bands offering intercontinental DX during the night.
*SpaceWX* Tomorrow is an excellent day for DX on the upper bands. The ionosphere has recovered from the “Easter storm,” and the MUF(F2) will break the 28 MHz mark. A sudden “radio blackout” cannot be completely ruled out, the probability of M-class flares is 55 percent. #spaceweather #hamradio #hamr
HF #Propagation Report (SA-MO) - Earth remains initially affected by a high-speed solar wind stream (HSS) and CMEs. Small chance of stormy intervals. Solar activity is moderate; further M‑flares are likely (M 55% X 15% Proton 15%). HF conditions are expected to recover. #spaceweather #hamradio #hamr
HF #Propagation Report - Because of high‑speed solar wind (HSS, ≥650 km/s) geomagnetic activity is likely unsettled to stormy (Kp 3–6); solar activity is moderate (M3.5 02/1815 UTC). Further M-flares are likely (M 55 % X 15 % Proton 10 %), HF conditions are degraded. #spaceweather #hamradio #hamr
Between 1630 and 1730 UTC, the K-index exceeded 6. #spaceweather #hamradio #hamr
HF #Propagation Report - Due of CME and coronal wind effects, geomagnetic activity is unstable to active, with likely stormy intervals. Solar activity is moderate (M3.5 02/1816 UT), and the risk of flares is elevated (M 55% X 15% Proton 10%). HF conditions are poor. #spaceweather #hamradio #hamr
HF #Propagation Report - We are still expecting a CME to arrive. Geomagnetic activity will remain mostly quiet; upon the CME’s arrival, G1–G2-class storms (Kp 5–6) are possible.
