The CME from the X5.1 flare has not arrived yet. Here are the websites I use: https://www.swpc.noaa.gov/ https://www.swpc.noaa.gov/ https://www.swpc.noaa.gov/

- apawloski 10mo agoThat's what I'm most curious about -- how do you see that it hasn't arrived yet when you're looking at SWPC? Here is the SWPC forecast [0] Time_UTC,Nov_12,Nov_13,Nov_14 00-03UT,8.67 (G4),6.67 (G3),4.67 (G1) 03-06UT,8.33 (G4),6.33 (G2),4.00 06-09UT,7.00 (G3),6.00 (G2),3.33 09-12UT,7.00 (G3),4.67 (G1),3.67 12-15UT,6.00 (G2),4.00,3.33 15-18UT,5.67 (G2),3.33,3.00 18-21UT,7.67 (G4),4.33,3.00 21-00UT,6.00 (G2),4.67 (G1),3.33 So I guess 18-21UTC today it'll get around 7.7kP, but that's lower than what hit this morning, when I'd expect X5.1 to be larger? Is that how I should interpret this? [0] https://www.swpc.noaa.gov/communities/space-weather-enthusiasts-dashboard https://www.swpc.noaa.gov/communities/space-weather-enthusia...
- drmpeg 10mo agoYes, you have it correct. However, predicting the effects of solar flares is very difficult. Not only does the particle stream have to hit the Earth, it has to couple with the magnetic field. Large flares can cause small events on Earth and vice versa.
- apawloski 10mo agoThanks for clarifying. I’m bummed that I didn’t prioritize going out last night to observe. I was thinking bigger glare would be better aurora tonight.
