HF #Propagation News - Earth has entered a high-speed stream of solar wind flowing from an equatorial coronal hole. #spaceweather #hamradio #hamr

HF #Propagation Report - Geomagnetic activity will become unsettled to active (Kp 3-4), with possible G1/minor storms (Kp 5). Solar activity has been low over the past 24 hours, little change is expected (M15% X01% Proton 01%). On Sunday, propagation will be disturbed. #spaceweather #hamradio #hamr

HF #Propagation Report - Geomagnetic activity is predominantly quiet, later becoming unsettled to active. Solar activity is moderate (M 25% X 05% Proton 05%). During the course of Sunday, HF propagation will be disturbed by fast solar winds from a coronal hole. #spaceweather #hamradio #hamr

HF #Propagation News - On the sun's side facing Earth, a powerful coronal hole extends along the equator. Depending on the orientation of the interplanetary magnetic field (IMF), we can expect geomagnetic disturbances from late weekend onwards. #spaceweather #hamradio #hamr

HF #Propagation Report - Geomagnetic activity is predominantly quiet. Solar activity is also expected to be predominantly low (M 10%, X 01%, Proton 05%). The same applies to tomorrow. #spaceweather #hamradio #hamr

HF #Propagation Report - Periods of active to weak stormy geomagnetic activity are still to be expected as two slow-moving CMEs pass the Earth. Solar activity will remain low with the possibility of isolated M-flares (M 35% X 10% Proton 05%). Moderate propagation condx. #spaceweather #hamradio #hamr

HF #Propagation Report - CMEs are expected to arrive this evening. Geomagnetic activity will first be quiet to unsettled, later active, with possible stormy periods. Solar activity remains low, with the possibility of isolated M-class flares (M 40% X 10% Proton 10%). #spaceweather #hamradio #hamr

HF #Propagation Report - Solar wind speeds will continue to decrease. Geomagnetic activity is quiet to unsettled until the arrival of a CME, later storm intervals are possible. Solar activity are low. Isolated M flares are still likely (M 45% X 10% Proton 10%). #spaceweather #hamradio #hamr

HF #Propagation Report - Fast solar winds are currently around 600 km/s. Therefore, we must expect mostly unsettled to active geomagnetic condx. Solar activity is moderate, with further isolated M-flares likely (M55% X10% Proton05%). HF conditions are moderate to good. #spaceweather #hamradio #hamr

HF #Propagation Report - Fast solar wind continues to cause mostly unsettled to active geomagnetic activity. This has a negative effect on the lower bands. In contrast, solar activity remains low, only isolated M-flares are likely (M 60%, X 15%, proton 05%). #spaceweather #hamrdaio #hamr

HF #Propagation Report - We are observing fast solar winds with speeds of 700 km/s and more, so the NOAA is warning of level G3 (K=7) and higher. Solar activity has been moderate over the last 24 hours with two minor M-flares, further are expected (M60% X15% Proton05%). #spaceweather #hamradio #hamr

HF #Propagation Report - Fast solar winds traveling at speeds of 650 km/s and above are causing ongoing turbulences in the Earth's magnetic field. Solar activity has been moderate over the past 24 hours. Further M-class flares are expected (M 60%, X 15%, proton 05%). #spaceweather #hamradio #hamr

HF #Propagation Report - Geomagnetic activity will remain mainly quiet to unsettled. But, a possible CME influence is to be likely. With two M-flares, solar activity has been moderate over the last 24 hrs. Further flares are to be expected (M 55%, X 10%, proton 01%). #spaceweather #hamradio #hamr

HF #Propagation Report - Geomagnetic activity is expected to be predominantly quiet at first. However, activity is likely to increase over the weekend. Solar activity is moderate, with no change currently in sight (M 30% X 05% Proton 01%), with MUF values >30 MHz. #spaceweather #hamradio #hamr

HF #Propagation Report - Geomagnetic conditions are expected to be predominantly quiet. Solar activity is moderate, with further isolated M-flares likely (M 35%, X 01%, Proton 01%). With MUF values above 30 MHz, we have elevated HF conditions. #spaceweather #hamradio #hamr

HF #Propagation Report - Coronal solar wind is still blowing, but has little effect on the Earth's magnetic field (Bz +). Geomagnetic activity is therefore expected to be calm, with occasional periods of turbulence. Solar activity is moderate (M 35% X 01% Proton 01%). #spaceweather #hamradio #hamr

HF #Propagation Report - The fast coronal solar wind (> 500 km/s) will decrease during the day. Quiet to unsettled geomagnetic activity is then expected. Solar activity remains low, but could increase moderately due to isolated M-flares (M 35% X 01% Proton 01%). #spaceweather #hamradio #hamr

HF #Propagation Report - A fast wind (> 600 km/s) from a coronal hole is expected shortly, which will lead to a active to stormy geomagnetic conditions. Solar activity is low, nevertheless, there is still a possibility of M-flares (M 40% X 05% Proton 05%). #spaceweather #hamradio #hamr

HF #Propagation Report - Geomagnetic activity is expected to remain mostly quiet to unsettled (Kp 1-3) over the next three days. In general, solar activity is expected to remain low, but there is a possibility of isolated M-class flares (M 35% X 01% Proton 01%). #spaceweather #hamradio #hamr

HF #Propagation Report - Geomagnetic activity will remain quiet to unsettled, with the possibility of active intervals. Low solar activity is expected. By increasing magnetic complexity of sunspots, there is a possibility of isolated M-flares (M 35% X 01% Proton 01%). #spaceweather #hamradio #hamr

HF #Propagation Report - Geomagnetic activity is expected to be quiet to unsettled, with the possibility of active intervals. Solar activity is low, with isolated M-flares increasingly possible (M 30%, X 01%, proton 01%). #spaceweather #hamradio #hamr

HF #Propagation Report - Fast solar wind (>750 km/s) continues to flow toward Earth from a coronal hole. Geomagnetic activity is unsettled to active (Kp3-4), with the possibility of further stormy intervals. Solar activity is low (M 30% X 05% Proton 01%). #spaceweather #hamradio #hamr

HF #Propagation Report - A little later than expected: a strong geomagnetic storm (G3) occurred during last night. The speed of the solar wind reached ~750 km/s. Solar activity is low, with a possibility of an M-class flare (M 25% X 01% Proton 01%). Bad HF band condx. #spaceweather #hamradio #hamr

HF #Propagation Report - Geomagnetic activity will be mostly quiet. On Sunday an increase (active to stormy / G1) is expected. The occurrence of M-flares is rather unlikely (M 20% X 01% Proton 01%). Moderate to good propagation conditions during undisturbed phases. #spaceweather #hamradio #hamr

A plasma movement in the southern heliosphere has triggered a southward-directed CME (11/1026 UTC) that could graze the Earth on Sunday. Amplified by fast solar wind from a large coronal hole, this CME could interfere with the WAE DX Contest on September 13/14. #spaceweather #hamradio #hamr

HF #Propagation Report - The solar wind speed is waning. Geomagnetic activity will be predominantly quiet until Sept 14, with possible isolated periods of disturbance. Solar activity will be predominantly low, with isolated M-flares possible (M 30%, X 01%, proton 01%). #spaceweather #hamradio #hamr

A huge hole has formed in the sun's atmosphere, from which fast solar wind (HSS) is flowing toward Earth. This will have a negative impact on propagation conditions, most likely as early as September 13/14. G1 magnetic storms are then possible. (Photo: SDO/AIA) #spaceweather #hamradio #hamr

HF #Propagation Report - Geomagnetic activity is expected to be predominantly quiet to unsettled, active intervals are possible when Bz value is negative for a longer period. Solar activity is weak, with only a low probability of isolated M-flares (M25% X01% Proton01%). #spaceweather #hamradio #hamr
