Many thanks to SWLing Post contributor, Richard Langley, who writes:

As monitored here in NB on 15 MHz today (31 January), WWV ended the National Weather Service Atlantic and Pacific marine high-seas and storm warnings after 19:00 UTC. Before that time, announcements about the ending of the warnings were transmitted during minutes 4 and 7 after the hour with the Atlantic information in minutes 8 and 9 and the Pacific information in minute 10. So, the last storm warnings were during the 18:00 UTC hour. After 19:00 UTC, the announcements in minutes 4 and 7 were discontinued and the storm warnings in minutes 8, 9, and 10 were replaced with an announcement about the ending of the warnings. Presumably, there was a similar transition on WWVH.

Thanks for the report, Richard!

In terms of an overall update about WWV in the 2019 NIST budget, there has been no real news to report. It seems the funding level for the Laboratory Programs (where the radio stations reside) will be funded at the same level as it was in 2018. Of course, NIST can internally-allocate many of their funds as they wish. Many thanks to SWLing Post contributor, Richard Cuff, who’s been keeping an eye on this budget process.

I must admit that I find it interesting WWV, WWVH and WWVB all continued to operate as normal during the Federal Government Shutdown.

Subject: Discontinuation of NWS High Seas and Storm Warnings
over NIST Time Frequency Broadcasts Effective January 31, 2019

Effective Thursday, January 31, 2019, at 200 pm Eastern Standard Time (EST) or 1800 Coordinated Universal Time (UTC), the NWS will discontinue dissemination of High Seas and Storm Warnings portion of the National Institutes of Science and Technology (NIST) time frequency broadcasts as issued by WWV and WWVH “shortwave” radio covering the Atlantic, Gulf of Mexico and the Pacific.

This service is being terminated because weather information in the current broadcast format does not support frequent enough updates for changes in marine weather and cannot provide enough detail in the allotted window required by mariners to avoid hazardous weather. Additionally, alternative technologies and numerous media outlets that provide weather information in various formats have overtaken the need for providing weather information through the NIST frequency signals.

Other sources of marine weather and high seas alerts and detailed forecasts are available over satellite, telephone, the Internet, Marine Fax, Radio Fax and VHF radio. Currently the NWS, U.S. Coast Guard (USCG), and the U.S. Navy (USN) provide multiple dissemination methods for storm positioning, high sea areas, observations, forecasts, outlooks and warnings for both coastal and oceanic marine zones near the United States using Navigational Telex (NAVTEX), Global Maritime Distress and Safety System (GMDSS) and High Seas SImplex Teletype Over Radio (HFSITOR) in compliance with World Meteorological Organization (WMO) policies and the International Safety of Life at Sea (SOLAS) Convention.

WWV & WWVH marine storm warning announcements continue

Many thanks to SWLing Post contributor, Richard Langley, who notes that WWV & WWVH marine storm warning announcements continue despite a recent announcement that they would end.

Richard has been monitoring WWV/WWVH broadcasts and shared the following note earlier this month:

The weather broadcasts (storm information) were still there at 8, 9, and 10 minutes past 0:00 UTC on 1 November on WWV as monitored here in NB. Haven’t had a chance to check them since. Are they actually gone? If so, when were the last ones broadcast. The warning at the 4-minute mark hadn’t been heard for days. I’m wondering if the decision to terminate the broadcasts was reversed.

Yesterday, Richard added the following:

[…]And still there on WWV (and presumably WWVH) on 16 November at 03:08 UTC on 10 MHz. So I guess this conclusively means that the proposal to cancel the broadcasts has been rescinded at least for the time being.

Thanks for sharing this, Richard.

Your observation prompted me to check the NOAA Marine Forecast page. I discovered that it has been updated it since the notice to stop marine forecasts was first announced last month.

Before, it stated that the “end of the high seas warnings [is] scheduled for October 31, 2017.” Either NOAA made the decision to end the the forecasts in 2017 and never followed through, else the individual who posted the announcement mistakenly noted 2017 instead of 2018.

NOAA does not note edit dates on this page, so there’s no way of knowing when the page was updated. Regardless, there is no longer a firm termination date mentioned on the page. Now the National Weather Service simply states:

“the NWS is considering a proposal to discontinue this service.”

So I believe, Richard, you are correct: the NWS has at least temporarily rescinded cancellation of the service.

Thanks for following this development, Richard!

WWV & WWVH to drop NOAA marine storm warning announcements October 31, 2018

Many thanks to SWLing Post contributor, Dave Zantow (N9EWO), who notes that WWV and WWVH are announcing the end of marine storm warning announcements on October 31, 2018.

This morning, I made the following recording of the announcement via WWV 5 MHz at 4 minutes past the hour:

Last year this time NOAA announced the end of the high seas warnings scheduled for October 31, 2017.

IEEE Spectrum: “Long-Running U.S. Federal Radio Stations, Beloved by Hams, in Danger of Shutdown”

A WWV Time Code Generator

(Source: IEEE Spectrum Magazine)

Several public radio stations that have broadcast the time of day continuously for nearly 100 years are on the chopping block

By Julianne Pepitone

Starting in May 1920, the U.S. federal WWV radio stations have broadcast the official time without fail. For ham radio fans, hearing the friendly “National Institute of Standards and Technology Time!” announcement is a comforting old refrain. For others, it’s a service they’ve never heard of—yet in the background, it’s what keeps the clocks and appliances in their daily lives automatically ticking along on time.

But after 98 years, this constant companion could soon go off the air. The proposed 2019 U.S. presidential budget calls for a 34 percent cut in NIST funding; in response, the Institute compiled a budget-use plan that would eliminate the WWV stations.

At first blush it might sound like the natural end to a quaint public service from a bygone era. Do we really need radio-broadcast time signals in an era of Internet-connected devices and GPS?

Many would argue: Yes, we really do. More than 50 million devices in the United States—including wall clocks, wristwatches, and industrial appliances—keep time through the signal from NIST’s WWVB station, operating from a site near Fort Collins, Colo., where it reads the time directly from an atomic clock. These radio-equipped clocks are permanently tuned to WWVB’s low-frequency 60 kHz signal.

“WWVB is the pacemaker for the world around us, even if we don’t realize it,” says Thomas Witherspoon, editor of shortwave radio news site The SWLing Post. “It’s why factory workers and schools don’t need to drag out the stepladder every time we switch between Daylight and Standard Time. Without WWVB, these devices won’t magically update themselves.”[…]

Marketplace: “Time may be up for timekeeping radio stations”

The Trump administration wants to shut down two shortwave radio stations that broadcast time signals from the nation’s master clock.

The administration’s budget proposal would eliminate nearly $27 million in funding from the National Institute of Standards and Technology for the two stations. WWV, based in Fort Collins, Colorado, has been transmitting one rock-steady pulse per second for more than 80 years. Its sister station, Hawaii’s WWVH, has been extending the time signal across the Pacific for nearly 70 years. WWV is also the world’s longest continuously-broadcasting radio station. (NIST doesn’t stream the stations online because signals are often delayed as they stream over the internet. But you can hear the stations by calling (303) 499-7111 for WWV or (808) 335-4363 for WWVH . There are also online recordings of the stations’ gentle announcements.)[…]

If you feel strongly about keeping the atomic clock signals on the air, I urge you to contact your local representatives,and sign this White House petition.

Astronomers organizing to save WWV

As an amateur astronomer, I knew it was only a matter of time before the astronomical community became involved to save WWV.  Specifically, it’s a group of mostly amateur astronomers who observe and record occultations.

What’s an occultation?  It’s the term when a solar system object passes in front of, and blocks out a star.  Why is this important to observe?  Lunar occultations are the easiest to observe (if the star is bright enough, one can do a crude observation with binoculars or even the unaided eye).  But there is very valuable science to be had with smaller objects.  When a dwarf planet [like Pluto] or an asteroid – passes in front of, and “blinks” out or blocks the light of a star – measurements can be taken that reveal the dwarf planet or asteroid’s size/diameter.  We can even determine if an object is round/oval – or maybe cigar-shaped when multiple ground observers record and accurately time how long the star “blinks” (or if the star doesn’t get covered by the asteroid in some locations but does in others). Okay, that is Occultations 101 (if you are interested in learning more, see the link).

Note 2: Multiple occultation observations involving the dwarf planet Pluto (and its next target – a “KBO”) are helping scientists navigate the New Horizons space probe (and to identify hazards) as it speeds through space to its next target – nicknamed Ultima Thule – beyond Pluto (on January 1st, 2019).

Equipment used to record and document these fleeting events (some graze occultations only last fractions of a second) requires – you guessed it – time stamped video devices.  Back in the old days before video and other advanced equipment, astronomers would sit a shortwave radio next to the telescope with a tape recorder to audibly capture & record the time signal with the observer noting the start/stop of the event (we’ve come a long way since then – time stamped equipment has advanced this from “approximately” to “exact science”!).

The main point of this blog entry: astronomers have been asked to sign the White House petition to maintain NIST stations funding. Sky & Telescope Magazine, if they haven’t already, will be posting an article with an interview that they conducted with one of the leading occultation observers that includes a link to the petition on their web site.

Let’s hope this momentum continues to build – and that it makes a difference!
