Sunspots Numbers for September 2019

Sunspot191007

In the last four months the Sun has produced practically no sunspots. There were two in June, two in July, and one in August. The September graph, (above)  shows that the past month was as weak as August, with only one sunspot again.

A periodic solar event called a "grand minimum" could overtake the sun perhaps as soon as 2020 and lasting through 2070, resulting in diminished magnetism, infrequent sunspot production and less ultraviolet (UV) radiation reaching Earth — all bringing a cooler period to the planet that may span 50 years.

Department of Defense Message Prompts Listeners to Take WWV/WWVH Survey

2010MarsLogo

Through Saturday, August 24, WWV and WWVH will transmit a US Department of Defense (DOD) message in conjunction with the COMEX 19-3 interoperability exercise in Tennessee. The broadcast also urges listeners to complete a surveyon WWV/WWVH listenership and listening habits. The messages are broadcast on WWV at 10 minutes past the hour and on WWVH at 50 minutes past the hour. WWV and WWVH transmit on 2.5, 5, 10, 15, 20, and 25 MHz.

Following a proof of concept this year, DOD anticipates making use of the WWV/WWVH broadcast time slot full time, all year.

Concern arose in 2018 after WWV and WWVH were included on a list of proposed cuts in the Administration’s Fiscal Year 2019 budget request for NIST.

NIST FY 2019 Budget Would Eliminate WWV and WWVH

The National Institute of Standards and Technology (NIST) FY 2019 budget request includes shutting down “NIST radio stations in Colorado and Hawaii” — in other words, WWV and WWVH. Radio amateurs, HF listeners, and others around the world routinely make use of the time and frequency standard signals, which also include propagation information. NIST said eliminating funding currently “supporting fundamental measurement dissemination” would include putting WWV and WWVH off the air for a saving of $6.3 million. The NIST FY 2019 budget request for efforts related to Fundamental Measurement, Quantum Science and Measurement Dissemination is $127 million, which, the agency said, is a net decrease of $49 million from FY 2018 levels. The Administration's overall NIST budget request is more than $629 million.

“The proposed reductions will allow NIST to consolidate and focus on narrower core [fundamental] measurement programs while meeting budget levels,” the agency said in its FY 2019 budget summary. “NIST will focus on basic research while reducing funding for efforts applying some of its breakthroughs into new measurement applications.

NOAA Space Weather

Latest
The NOAA Space Weather Scales were introduced as a way to communicate to the general public the current and future space weather conditions and their possible effects on people and systems. Many of the SWPC products describe the space environment, but few have described the effects that can be experienced as the result of environmental disturbances. These scales are useful to users of our products and those who are interested in space weather effects. The scales describe the environmental disturbances for three event types: geomagnetic storms, solar radiation storms, and radio blackouts. The scales have numbered levels, analogous to hurricanes, tornadoes, and earthquakes that convey severity. They list possible effects at each level. They also show how often such events happen, and give a measure of the intensity of the physical causes.

Light Up 2 Meters Night, an FM Simplex Event

Most Amateur Radio Operators today start out with a radio capable of operating FM on the 2 meter band, so, you probably already have the minimum equipment necessary to participate. The objective is simple - make 2 meter FM simplex contacts, challenge your operating limits, and just get on the air and have some fun.


The suggested frequency for this event is 146.55 MHz, if calling on 146.52 MHz, please be considerate of other operators. Your local band plan may differ, so feel free to share with suggested frequencies that would be best in your local area.

Now all you have to do is get on the air! Of course, you don't have to stop there, maybe your station needs an upgrade, whether it’s a handheld needing a better antenna, to the 100' of 30 year old RG8X to your 2 meter vertical on the tower needing replaced, or maybe, a new mobile rig has been on your shopping list.

2 Meter Tropo, August 11, 2018

Good Tropo on 2 meters again this morning. Not quite the band conditions of the previous two nights but still not too shabby.
