Magnitude X8 X-ray Flare of Sept 9 2017 (2nd Biggest in Cycle 24)
The sun erupted with an X8 solar flare, one of the largest of the current solar cycle (Sept. 10, 2017). Its source was the same sunspot region that produced an X9 flare last week. We show this in two wavelengths of extreme ultraviolet light at the same time, and each reveals different features. Both are colorized to identify in which wavelength they were observed. The coils of loops after the flare are the magnetic field lines reorganizing themselves after the eruption. The video clip covers about six hours.
FCC Opens 630/2200 Meters Amateur Band; Pre-Registration Required!
Yes, the headlines read, “FCC OPENS 630/2200 METERS TO AMATEUR USE AS OF OCTOBER 16, 2017; PRE-REGISTRATION REQUIRED.”
The FCC has authorized amateur radio use of the 630 and 2200-meter bands, effective October 16, 2017, providing registration procedures have been followed and no objections are received within 30 days.
The PLC (Power Line Communications) database is live and hams may begin registering immediately. They may begin operating on 472 kHz (630 meters) and 137 kHz (2200 meters) as early as October 16 if they register today and receive no objection in the next 30 days. Hams may not operate on the bands without going through this process.
Please fill out the UPC Form, today, to register your station, even if you don’t have any plans on transmitting on these new bands.
It is imperative that all amateurs register, even if they don’t plan to use these bands in the near future, as the FCC rules prohibit UTC (the Utilities Technology Council) from deploying PLC in these bands closer than one (1) kilometer from registered stations. Registration now will protect your ability to use our new MF/LF bands in the future.
