Bengt Arne Alfredsson (1962-2019)
A LIFE WELL TRAVELLED
by Joe Cali
Bengt
Arne Alfredsson was born in Vanersborg Sweden in January 1962. He
attended school in Vanersborg and then moved to Goteborg in 1981 at the
age of 19 and working for Hasselblad for 2 years assembling the iconic
6x6cm square medium format 500 series camera bodies. He left Hasselblad
and completed his compulsory military service before completing a
degree in Physics.
He chased his first eclipse in Finland in 1990. This effort,
unfortunately, was unrewarded, with heavy rain washing out the event.
He tried again in 1991 with a trip to Sayulito, Mexico just north of
Pueto Vallarta on an expedition organized by the late Tom Van Flandern.
The expedition was an edge expedition where the group went close to the
southern limit where only 2min 6 seconds of totality was visible.
At the centre line, close to 7 minutes totality was possible.
While this type of observation may well be interesting for experts,
Bengt always regretted his decision feeling that for this first
successful eclipse, he wasted 5 minutes of totality due to his lack of
understanding of the type of expedition he joined. He said later that
if he knew then what he knew later, he would have caught a taxi north
further into the umbra from the groups observing site and picked up a
minute or more of totality. Instead it was a brief but spectacular
enough experience that it whet his appetite for more.

After
1991, Bengt took a long break from eclipse chasing while he completed
his M. Sc. in radiophysics at the Onsala Radio Observatory in Sweden.
His thesis topic was originally related to GPS and communication and
tracking of high-flying scientific balloons. This project didn't work
out and so he switched to a thesis where he created a computer network
at Onsala to assist with porting radio telescope receiver data from
mini main frames to Macintosh computers for post analysis and
publication.
Just after finishing up his masters thesis he decided to catch the
Trans-Siberian Railway to Chita, Siberia, west of Lake Baikal, to
observe the March 1997 total solar eclipse. Prior to leaving Sweden and
while planning the trip, he wrote to a university physics department in
Chita on Onsala Observatory letterhead. It wasn't a deliberate
deception, but they formed the impression that he was a distinguished
senior academic from Onsala observatory. On arrival at Chita, they
rolled out the red carpet for him. At Chita during this eclipse,
Bengt met Glenn Schneider, Joel Moskowitz, and Craig Small for the
first time.
Following this eclipse, he chased two more, travelling to El Vinculo,
Venezuela in February 1998 and then to the Black Sea Coast at a resort
north of Varna, Bulgaria in August 1999. In Bulgaria, Bengt was
surprised that, at the location he chose, not only were there no
eclipse chasers, but that nobody on the beach at the resort was even
aware that the eclipse was in progress until he showed them through his
eclipse glasses.
Professionally and
personally, he had now taken up residence in Goteborg, Sweden's second
largest city and using his background in communications technology,
began working for a private company that designed and built security
& communication systems for large scale facilities such as mines,
ports, & factories.
In May 2001, Bengt made a post to the solar eclipse mailing list asking
if anybody wanted to team up with him in Zambia. I was in the midst of
making a late decision to chase this eclipse and replied to his post.
We met up for the first time in Zambia, observed an amazing eclipse and
our friendship was forged.

In
2002, Bengt came to Australia, we observed a remarkable sunset eclipse
from Cameron Corner and after the eclipse, toured through the South
Australian wine regions and the Great Ocean Road in Victoria. This set
the framework for our eclipse chasing and our long friendship. One of
the keys to our friendship was a synergy in outlook. Neither of us were
the types to fly across the world, watch an eclipse, then fly home.
Every trip had some interesting travel tacked on before or after the
event.

though he had a license, he didn't like to drive preferring to navigate and drive his GPS.

Bengt was posing for this photo he was telling me to hurry up because he was
burning his arm on the hot car hood.

Over the next two
decades, we formed a very successful eclipse chasing partnership and
even firmer friendship. We chased total solar eclipses in 2001, 2002,
2006, 2008, 2009, 2010, 2012, 2013, 2015, 2016, 2017 being clouded out
just once in 2009 in Shanghai. We also observed an amazing sunrise
annular eclipse in May 2013. When eclipses were not on we did some
other travels. Bengt loved Australia and so in 2007, we explored far
north Queensland then took my Hilux to beautiful Fraser Island.

I
think for both of us, a few experiences really stand out, the first
eclipse we chased together in Zambia with hundreds of villagers
chanting singing and dancing around us for its rich cultural
experience. For sheer natural beauty and isolation, the eclipses
on Tatakoto Atoll in 2010 and Svalbard in 2015. We also spent a week
exploring the amazing Yellowstone National Park, not so isolated, with
thousands of other people in August 2017.

Upon
receiving his grim diagnosis late in 2017, we had some very frank
discussions. I asked him if I could come and visit him or if he wanted
me to come through Sweden and collect him and we could go somewhere
else to escape the Swedish winter. I asked him to think about the place
he most wanted to go since this would probably be his last opportunity
before becoming too ill to travel. He didn't hesitate to select the
iconic national parks of central and northern Australia, Kakadu, Uluru,
Kata Tjuta and the MacDonald Ranges. I remember he described them
as his last dark place on Earth meaning the one place he had not seen
but wanted to explore. He had previously attempted to work a
visit to these parks into each of his prior trips to Australia but
something always got in the way. In recent years, we had often
talked of visiting them together as an extended road trip before and
after the 2028 total eclipse when we would both be retired and have
time on our hands.
Early in 2018, he came to Australia and we went to Uluru, Kata Tjuta,
MacDonald Ranges and Kakadu. It was clear that we only had a
short window in which to do this before he would be unable to travel at
all. I had visited these parks on several occasions in the past
and so using that local knowledge, I was able to plan the trip in such
a way that it wasn't too difficult for him to manage.
