Geomagnetic storm on the way

[Slowpoke]

Will this effect skip positively or negatively?

A strong geomagnetic storm is heading toward Earth, space forecasters say

NOAA's Space Weather Prediction Center has issued a geomagnetic storm watch triggered by "coronal mass ejections" that may briefly disrupt satellite communications — and create a stunning aurora display — this week.

All geomagnetic storms upset radio propagation. Usually HF dies while VHF and UHF are enhanced via Aurora propagation.

Well, ok then! Thank you. Do the effects last long?

Sometimes a few hours, sometimes a day or two. It depends on the strength of the storm and whether it hits us head-on or a glancing blow. I have been on the air with a noisy band and within a couple minutes ALL DX signals fade and drop out. You would swear the world just ended. Eerie. Later things eventually come back.

captain killowatt. this morning at 5 am cst my radio would pick up hash then drop it several times ,is that it?

Same here in SoCal…raging until around 7pm.

Solar Activity

.24 hr. Summary...
Solar activity reached moderate levels following an impulsive M2 flare
at 17/1345 UTC followed quickly by an M1 flare, both from region 3078
(S24W42, Dac/beta-gamma-delta). The region also produced an impulsive M1
flare at 18/1009 UTC and a M1 at 18/1055 UTC with Type II (749 km/s
S.V.) and Type IV radio sweeps. The region continued to be the most
active and magnetically complex spot group on the visible disk producing
numerous C-class flares as well as the M-class activity.
2022 Aug 18 1454 UTC
Synoptic Period: 1500-1800 UTC

Active Warning: No
NOAA Scale: G1 - Minor

NOAA Space Weather Scale descriptions can be found at
www.swpc.noaa.gov/noaa-scales-explanation

Potential Impacts: Area of impact primarily poleward of 60 degrees Geomagnetic Latitude.
Induced Currents - Weak power grid fluctuations can occur.
Spacecraft - Minor impact on satellite operations possible.
Aurora - Aurora may be visible at high latitudes, i.e., northern tier of the U.S. such as northern Michigan and Maine.

ALERT: Type II Radio Emission
Begin Time: 2022 Aug 18, 1049, UTC
Estimated Velocity: 749 km/s
Description: Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event. (Temp BLACKOUT)

Geomagnetic Field and Aurora

Past 24 Hours: Storm

Aurora was seen last night as far SOUTH as North Central Indiana

.Forecast..
Solar activity is expected to be low with a
chance for M-class flares (R1-R2 Minor-Moderate radio blackouts) and a slight chance for X-class flares (R3-Strong radio blackouts) on 18-20 Aug.

It's weird as heck when that happens. Usually it's when my back is turned, typing on the PC keyboard, listening to whatever DX there is and then...silence... Even now, after being a veteran of many solar storms, it'll still get to me ("Arrrrgh...it broke)

Tasmania and Florida coming into SoCal. Kinda weird…not much in between.
