In reference to the x-ray flux graph below:
"Sharp eyes might have noticed a very abrupt drop on the solar X-rays graph today. What happened to the Sun? It went into cardiac arrest? Nope. Today, December 9, the NOAA SWPC has switched to GOES-16 as the primary satellite for geostationary space weather observations. What does that mean?"

17:27 WA4LDU-JOE: hearing WB8PMD on CW
17:34 K5HFG: copy KG0VL SSB 58
17:37 K4FI-DOUG: KW4DE is strong here, KP2AE is up and down
17:37 K5HFG: Jeff, I heard you but it faded to noise. I can hear peaks but no copy
17:40 W4DEX-DEX: KG0VL Q5 S5 SSB, 579 CW
17:41 K4FI-DOUG: KG0VL Very weak on CW
17:42 K5HFG: copy KG0VL 549 solid
17:42 WA4LDU-JOE: could see KG0VL signal in the noise on the scope at the beginning of his CW but no copy
17:42 W4DEX-DEX: KG0VL CW very little if any QSB
17:43 W4DEX-DEX: K5HFG CW 539
17:43 KP2AE-JOE: locals strong today...some copy of KG0VL
17:43 W4DEX-DEX: K5HFG CW QSB into the noise
17:44 W4DEX-DEX: WA4LDU 589
17:45 KG0VL-JEFF: Heard K5HFG 519 for about the first 20 seconds and then gone. Reappeared for the final 20 seconds in the same fashion.
17:46 K5HFG: no copy on WA4LDU. I see his sig on scope and hear occasional tone but no copy
17:46 KG0VL-JEFF: WA4LDU just above noise, but heard for the duration.
17:46 WA4LDU-JOE: K5HFG very light copy at first in the noise but then faded out
17:47 WA4LDU-JOE: W4DEX CW 599
17:48 K5HFG: copy W4DEX 519/529 solid
17:48 WB4WCJ-PAUL: CW wa4ldu w4dex
17:50 KG0VL-JEFF: W4DEX 579 good CW signal
17:55 K5HFG: Dex, I hear you 51 and returned but you cant hear me
17:56 W4DEX-DEX: You were heard by KW4DE
17:56 K5HFG: I had to use the narrow filter to hear you DEX, atmospheric noise here is loud
17:57 K5HFG: Strange propagation
17:58 K5HFG: Also had to use headphones
17:59 W4DEX-DEX: K5HFG, your signal was good enough during the CW peak for an SSB exchange, just didn't last long
18:01 K5HFG: SSB very light this morning. I can copy bits and pieces
18:01 W4DEX-DEX: KW4DE and I heard you but just barely
18:03 W4DEX-DEX: KP2AE also detected your signal Don
