DX Weather week 37/2026: flux rising against the NOAA table, CME impact on Tuesday
The 27-day table says 95 to 100 for this week. The flux is already at 111 and has been climbing since Tuesday. The reason sits on the left of the lead image: the new regions are arriving from the east limb.
DX Weather Week 36/2026: SFI slides from 143 to 116 — but equinox season is starting
From 143 to 116 in one week: the two regions that carried the flux are rotating over the west limb, and little is coming up from the east. NOAA sees 95 by the weekend. The good news is in the calendar.
DX Weather Week 35/2026: SFI 124 and a Quiet Field — but the Flare Risk Is Rising
A whole week between 124 and 129: the solar flux has settled, the geomagnetic field is quiet, no CME in sight. The catch lies elsewhere — Region 4513 is turning towards us, and for the first time in weeks SWPC sees a chance of M-flares again.
DX Weather Week 34/2026: SFI Back at 117 — The Bands Recover, the Field Wobbles at the Start of the Week
Six days, plus 23 flux points: after the slump to 94 the solar flux is back at 117 and the X-ray background has nearly quadrupled. The price is a CME at the start of the week. The outlook for week 34.
