HAM RADIO ACTIVE DURING ECLIPSE

Millions of people across the United States got to see a rare solar
eclipse on Monday, April 8, 2024.

The path of totality -- the line of darkness where the moon fully
occluded the sun -- stretched through the South Pacific, Mexico,
central Texas, the Ozarks, the Midwest, the Rust Belt area, and to New
England through the Maritimes. In all, 14 ARRL Sections were impacted
directly and several more were on the fringes of the solar umbra.

Radio Serves

Amateur radio was active throughout the areas of impact. Most ARRL
Sections in the path had been developing a plan with their served
agencies for months or years beforehand.

Traffic was expected to be significant, with up to 3.7 million
people forecast to travel to areas within the path of totality.

Radio amateurs were activated in many locations.

In Paris, Texas, hams split shifts at the Lamar County Emergency
Operations Center (EOC). Teams of two operators volunteered for 4-hour
shifts. The activation doubled as a training opportunity and an
equipment test.

The ARRL Indiana Section was in full force with their Amateur Radio
Emergency Service® (ARES®) member-volunteers providing radio coverage
on HF, VHF, and UHF amateur bands and utilizing GMRS. Using a mobile
command center dubbed "Big Blue," the ARES team in Lake County set up
on an overpass above Interstate 65 and was staffed in part by father
and son volunteer team Chris Lattimer, N9MMR, and Tavas Lattimer,
KD9NSC. The Section also utilized Winlink VARA HF to establish a
digital connection with the incident command system.

In Hamilton County, Indiana, ARES members volunteered with the county
emergency management teams. They fanned out across EOCs, parks, and
other locations. One ARES member, who is also active in the Civil Air
Patrol, monitored traffic and crowds from an airplane.

Section Emergency Coordinator of the ARRL Maine Section Keith Anoe,
KE4UCW, held hourly check - ins via radio with the Maine Emergency
Management Agency and other served agencies in case one of them needed
to activate the Maine Emergency Communication Net.

Social media posts throughout the amateur radio space hold anecdotes of
146.52 MHz being extremely active during the post-eclipse traffic jam.

Radio Gathers

In Vermont, several ARRL members, who also happen to be pilots,
gathered at the Northeast Kingdom International Airport in Newport to
watch the eclipse.

Outside ARRL Headquarters in Newington, Connecticut, staff members and headquarters volunteers took the opportunity to observe the 92% visible
eclipse using a solar viewer built by W1AW Station Manager Joe Carcia,
NJ1Q.

Radio Studies

Across the world, radio amateurs participated in the HamSCI Solar
Eclipse QSO Party. It involved operating before, during, and after the
eclipse to gather log data. Those logs will be studied by researchers
in the coming years to further investigate the sun's impact on the
ionosphere.

HamSCI's program leader Dr. Nathaniel Frissell, W2NAF, was active from
The University of Scranton Amateur Radio Club station. "I'm happy to
report that we had an excellent day at W3USR in Scranton and believe
that we both had fun and collected good data," he wrote in a message to
the HamSCI team.

The organizers request that those who operated in the event upload
their logs. If you used N1MM+ or N3FJP loggers, there's a setting
called Solar Eclipse QSO Party. Participants can also submit a Cabrillo
or ADIF file of their activity. All logs should go to https://seqp.contesting.com/seqpsubmitlog.php.

AMATEUR RADIO SAVES FAMILY IN DEATH VALLEY NATIONAL PARK

Death Valley National Park is in a remote desert in southern
California, where mobile phone networks are spotty at best. On
Saturday, April 6, a radio amateur and his family were enjoying the
park when their vehicle became stuck in mud in a dangerous area.
Without access to a cell network, the ham called for help on the
10-meter band.

According to a news release from the Black Swamp Amateur Radio Club,
Caleb Gustwiller, KD8TGB, jumped into action.

Gustwiller was monitoring from Ohio when he picked up the distress
call. He was able to hear the call sign and the general location of the
ham in distress. He lost the signal to the noise, so he wrote a post in
the Parks on the Air® Facebook group asking for other hams to listen
for the calls.

Several hams contacted emergency officials in southern California,
which led to the ham and their family being rescued within a few hours
by park rangers. The club stated in their Facebook post: "Without Caleb
hearing this distress call, it could have quickly become a very deadly situation for the operator and his family."

ACTIVE HURRICANE SEASON PREDICTED FOR 2024

Colorado State University (CSU) hurricane researchers predict an active Atlantic hurricane season (June 1 to November 30) in their initial 2024 forecast.

ARRL Director of Emergency Management Josh Johnston, KE5MHV,
attended the National Hurricane Conference in Florida in late March,
where the CSU prediction was issued. "The common discussion at the
National Hurricane Conference this year was the potential for a very
active year, and the forecast from CSU enforces that thought," said
Johnston. "Several of the forecasters were pointing to indications that
we are moving from an El Niño to a La Niña and that could potentially
cause a more active season."

The CSU Tropical Weather & Climate Research team <https://tropical.colostate.edu/> predicts 23 named storms during the
Atlantic hurricane season. Of those, researchers forecast that 11 will
become hurricanes and five will reach major hurricane strength, as
measured by the Saffir-Simpson Hurricane Wind Scale <https://www.nhc.noaa.gov/aboutsshws.php>, with sustained winds of 111
mph or greater. The prediction is above the 30-year average for
hurricanes and storms and is above the total of 20 storms, seven
hurricanes, and three Category 3 or higher hurricanes in 2023.

Senior Research Scientist in the Department of Atmospheric Science at
CSU and the lead author of the report Phil Klotzbach said, "So far, the
2024 hurricane season is exhibiting characteristics similar to 1878,
1926, 1998, 2010, and 2020. Our analog seasons were all very active
Atlantic hurricane seasons."

The team predicts that 2024 hurricane activity will be about 170% of
the average season from 1991 - 2020. By comparison, 2023's hurricane
activity was about 120% of the average season. The report also includes
the probability of major hurricanes making landfall, including a 62% probability for the entire US coastline. The average landfall from 1880
- 2020 was 43%.

The report also indicates increased landfall probabilities of 34% for
the East Coast of the US, including the Florida peninsula (the average
from 1880 - 2020 was 21%); 42% for the Gulf Coast, from the Florida
panhandle westward to Brownsville (the average from 1880 - 2020 was
27%), and 66% for the Caribbean (the average from 1880 - 2020 was 47%).

The National Weather Service (NWS), National Hurricane Center (NHC),
and Hurricane Watch Net (HWN) are prepared for an active hurricane
season. Amateur radio operators can take part in activations on 14.325
MHz during the day and on 7.268 kHz at night. As propagation changes,
the HWN may operate both frequencies simultaneously.

At the Florida conference, Johnston also highlighted the relationship
between ARRL and the Federal Emergency Management Agency (FEMA) <https://www.arrl.org/news/arrl-and-fema-sign-agreement-ham-radio-is-as-relevant-as-ever>,

as well as ARRL's position as a net control station within the SHAred
RESources High Frequency Radio Program (SHARES) <https://www.cisa.gov/resources-tools/programs/shared-resources-shares-high-frequency-hf-radio-program>

managed by the Cybersecurity and Infrastructure Security Agency.

"Now is the time to prepare for emergencies of any type by building relationships, training and refreshing skills, and testing and
preparing equipment," added Johnston.

ARRL TEACHERS INSTITUTE ON WIRELESS TECHNOLOGY APPLICATIONS DUE

BEFORE MAY 1

The ARRL Teachers Institute (TI) on Wireless Technology is a
donor-funded program created to train and equip educators to
incorporate amateur radio into science, technology, engineering, and mathematics (STEM) education in their classrooms. Hundreds of success
stories continue to emerge from the program. The next cohort of
teachers is forming now, and applications are due before May 1. A new
video allows prospective educators to hear from those who have already participated in the program. Click here <https://www.youtube.com/watch?v=ouvdYosSVM0> or on the image below to

WORLD AMATEUR RADIO DAY 2024

World Amateur Radio Day <https://www.iaru.org/on-the-air/world-amateur-radio-day/> (WARD) is
celebrated each year on April 18.

The theme for 2024 is, "A Century of Connections: Celebrating 100 Years
of Amateur Radio Innovation, Community, and Advocacy." The global event
covers all of the International Amateur Radio Union
<https://www.iaru.org/> (IARU) regions and spans 2 days: Thursday,
April 18, 2024, 0000 UTC to Friday, April 19, 2024, 0000 UTC.

On April 18, 1925, the IARU was formed in Paris and will celebrate its centenary in 2025. American Radio Relay League (ARRL) Co-Founder Hiram
Percy Maxim was the organization's first president.

All radio amateurs are invited to take to the airwaves to enjoy the
global friendship with other amateurs and to show their skills and
capabilities to the public. WARD is not a contest but rather an
opportunity to talk about the value of amateur radio with the public
and fellow amateur colleagues. It is also a great opportunity to talk
about local radio clubs and amateur radio in local media as a lead-up
to ARRL Field Day <http://arrl.org/field-day>, which is held each year
during the fourth full weekend in June. You can also promote your
personal WARD activities on social media platforms like X and Facebook
by using the hashtag #WorldAmateurRadioDay.

IN BRIEF...

Recipients of the 2023 Cass Awards have been announced. Dima Zhikharev,
RA9USU, received the Single-Operator Cass Award by working 13,784
unique stations during his 14-day, one-man DXpedition to Yemen's
Socotra Island, 7O73T -- a new record for this award category. The
Unlimited Cass Award was awarded to the Russian DXpedition Team, 9X5RU
(Vasily Pinchuk, R7AL; Leo Berezhnoy, RW9JZ; Slav Rodin, OK8AU; Victor Filimonov, UA3QLC; Nick Tolkunov, R5EC, and Mike Alekseev, RU3UR), for contacting 40,959 unique stations from Rwanda, setting a new record for
the Unlimited Cass Award category. Presented annually, these awards
honor past ARRL Pacific Division Vice Director and San Francisco
Section Communications Manager Hugh "Cass" Cassidy, WA6AUD (SK), from
San Rafael, California, who published the West Coast DX Bulletin
(WCDXB) for 11 years. These awards encourage DXpeditions to maximize
the number of DXers contacted by awarding plaques to the
Single-Operator DXpedition that contacts the most unique call signs
during a 2-week interval and to the Unlimited DXpedition that contacts
the most unique call signs during a 4-week period. The rules for each
award are defined at http://www.cassaward.com.

THE K7RA SOLAR UPDATE

Tad Cook, K7RA, of Seattle, Washington, reports for this week's ARRL Propagation Bulletin, ARLP0015:

This solar disk image was taken on April 11, 2024. [Photo courtesy of
NASA SDO/HMI]

I did not see last Monday's eclipse, except for on television. In
the Pacific Northwest, there was only a 20% exposure, and skies were
overcast. As reports from across the country displayed successive
totality, I noticed the prominence on the edge of the disk. There were
always between one and three little red spots at the edge.

Solar activity over the past reporting week, April 4 - 10, remains
weak.

The average daily sunspot number rose from 60 to 67.9, but the average
solar flux declined from 136.9 to 123.2.

Seven new sunspot groups emerged this week: one on April 4, three on
April 5, one on April 6, one on April 8, and one on April 10.

Here is the outlook for the next few weeks, which does not seem
promising. The solar flux will peak at 150 over the next week.

Predicted solar flux is 132, 140, and 145 on April 11 - 13; 150 on
April 14 - 17; 140 on April 18 - 20; 135 on April 21 - 22; 140 and 145
on April 23 - 24; 140 on April 25 - 26; 135, 125, and 120 on April 27 -
29, and 125 on April 30 through May 10.

Predicted planetary A index is 10, 5, 8, and 10 on April 11 - 14; 5 on
April 15 - 18; 8 and 10 on April 19 - 20; 8 on April 21 - 23; 5 on
April 24 - 27; 8, 8, and 7 on April 28 - 30; 10 on May 1 - 3; 5 on May
4 - 5; 8 on May 6 - 8, and 5 on May 9 - 15.

and 54, with a mean of 67.9. The 10.7-centimeter flux was 113.7, 120.5,
122.9, 124.6, 124.8, 124.4, and 131.2, with a mean of 123.2. Estimated planetary A indices were 12, 12, 10, 6, 8, 11, and 8, with a mean of
9.6. The middle latitude A index was 33, 10, 8, 5, 8, 10, and 7, with a
mean of 11.6.
