Senator Ted Cruz, in this pre-Memorial-Day message, thanks amateur (ham) radio volunteers who serve the public through emergency communications, readiness to meet public communications needs, and are ever-ready technical assets.

Senator Ted Cruz Highlights Amateur Radio Public Service (Memorial Weekend 2026)

Sen. Cruz highlights the role these amateur radio FCC-licensed volunteers have in providing essential communications when violent storms knock out communications in local and regional areas, when power is out, cellular communications limited or overwhelmed, and communications services are stressed beyond capacity. Senator Cruz notes that these ham radio operators step forward to provide first-response communications in many situations, and gives examples of such in recent years, such as the 2017 Hurricane Harvey emergency when the catastrophic flooding across Texas took so many lives, and ham radio was there providing critical emergency communications. This was again demonstrated in the horrible Camp Mystic floods. He emphasized that as the United States of America prepares for yet another Summer Season, ham radio volunteers are ready to step up and provide these essential amateur emergency communications services. His comments also reflect growing Congressional recognition of the value Amateur Radio Operators bring to communities across the country.

Senator Cruz is Chairman of the Senate Committee on Commerce, Science, and Transportation. His comments align with the ARRL’s ongoing efforts to strengthen and protect Amateur Radio’s role in emergency preparedness and public service communications. As a member of ARRL, I applaud the Senator’s acknowledgement of the service we amateur radio operators provide our communities.

My first QSO (and, yeah, it was with Morse code) was petrifying and…

What’s your story of your first QSO?

While many are talking about how Solar Cycle 24 is the weakest since the Maunder Minimum (the period starting in about 1645 and continuing to about 1715 when sunspots became exceedingly rare, as noted by solar observers of the time — see this Wiki entry), there are moments when activity on the Sun strongly increases, providing brief moments of excitement.

Here is a case in point, witnessed by the Solar Dynamics Observatory (SDO; see SDO Mission) on June 7, 2011, when the Sun unleashed a magnitude M2 (a medium-sized) solar flare with a spectacular coronal mass ejection (CME). The large cloud of particles mushroomed up and fell back down looking as if it covered an area almost half the solar surface.

SDO observed the flare’s peak at 1:41 AM ET. SDO recorded these images in extreme ultraviolet light that show a very large eruption of cool gas. It is somewhat unique because at many places in the eruption there seems to be even cooler material — at temperatures less than 80,000 K.

This video uses the full-resolution 4096 x 4096 pixel images at a one minute time cadence to provide the highest quality, finest detail version possible.  The color is artificial, as the actual images are capturing Extreme Ultraviolet light.

It is interesting to compare the event in different wavelengths because they each see different temperatures of plasma.
