Aurora Borealis Observing
When I first became
interested in astronomy as a teenager, I read everything I could find
about all the different types of astronomical phenomenae, aurorae among
them. They seemed fascinating yet out of reach being most visible at
very high latitudes.
In early March 2015, I visited Tromsø for some bucket list aurora observing.
We attempted observing on 5
nights Mar 12-16. Two nights were clear and had visible aurora
events. Two nights were cloudy the other partly clear but quiet with no
aurora. In an area that experiences 90% cloud cover most of the
year, we consider ourselves very fortunate.
The results are presented as
flash slide shows. These shows have a lot of images in them. The
best way to view these is to press the play button and leave the slide
show playing in the background, walk away or do something else on the
computer. Then after the show has played through once, all the
images will be in your cache. Use the forward backward buttons and skip
through the images quickly.
Mar 12th : Drove
to the Finland border from Tromsø. There were occasional patches
of clear sky through cloud and heavy snow falls but no aurora evens
Mar 13th, 14th, 15th : We
stayed at Yggdrasiltunet farm on Kvaløya. Great success on Saturday
14th. Cloudy other nights.
Mar 16th we drove from our
hotel in Tromsø back to the farm at Kvaløya for the evening (at
the owners kind invitation). That night turned out to be our second
successful night. Lower intensity display than Mar 14th but with

Notes for those planning Aurora observing tours to Tromsø
I a not an expert on
Tromsø nor is this a comprehensive report. It is based on
my limited experiences during a one week visit to the Tromsø
For those of us from middle
latitudes, there are a couple of things we are not accustomed to, that
we should keep in mind when planning any aurora observing at high
The Tromsø region is a
few degrees north of the Arctic Circle. Therefore, it
doesn’t become “astronomical dark” (Sun>18o below the horizon) at any point during the night if the Sun’s declination is greater than +3o
(March 30-September 14). The number of night hours change rapidly
throughout the colder months. See diagram. So the observing window for
latitudes near the Arctic circle is not before early October through to early March.
Graph showing the number of hours of darkness (time between astronomical twilights) throughout the year.
The data I generated for this plot was for 2015 but it will apply equally to any year. As you can see, hours
of dark reduces from 6hrs to nothing between March 11 and March 26 and increases from nothing to 6hrs
between September 14 and October 6. Plan any visits after mid-October and before early March.
New Moon can last for 2
weeks! What’s that you say? Have I gone mad? At those high
latitudes, the southern ecliptic doesn’t rise much. The last
quarter moon is in the southern hemisphere during March and at
such high latitudes only rises around the time of astronomical
twilight. During October/November, first quarter Moon is in the south
and likewise does not rise so you get most of the, admittedly short,
night free of the Moon.
So for a October visit, plan
your visit across New moon and first quarter, for a Feb,March try to
visit last quarter to New Moon.
Costs around Tromsø
All of Norway is expensive
compared to most countries in the world. With few exceptions, expect
prices to be about double what you pay in Australia.
Tromsø is certainly no exception.
Hotels are not double
but perhaps 50% more than Australia. Car rental is more than
double and taxi’s cost 6-7 times more. Batteries on the other
hand are cheaper. A take away meal like a pizza or burger will cost
Where to observe aurora?
You can see very bright
displays from Tromsø but there is a lot of light pollution and
as with all things astronomical, it’s much better to observe
aurorae from dark skies.
Commercial Northern lights tours
One night aurora all
inclusive tours ranged from AUD120 per person up to about AUD250
per night. These often included some sort of meal at an outdoor
campfire + transport. You can also hire tripods from some tour
companies for extra costs. I didn't take a tour. These
company’s travel long distances to the islands or to the Finland
border in search of clear skies. The Finland border is only 150km from
Tromsø so this is not as extreme as you might think. These
companies have big fire pits near the border and take the tours their
One night when I drove
our rental car to the Finland border, many of the northern lights tour
drivers I encountered were driving unsafely, even allowing for the snow
tyres. I was driving the roads out near the Finish border in our rental
car. On the way home, I was driving at the posted speed limit. During
the return trip, three different tour vans were tailgating us at
different points and then making unsafe and stupid overtaking moves.
Hitting moose weighing 450-650kg or reindeer (100-300kg) is a common
occurrence on those roads. My friend Geoff Sims hit one while we were
both there. Had we hit one, the tour van tailgating us would have
then crunched us from behind. For this reason alone, I cannot
recommend these tours.
Car hire is quite expensive
compared to other countries I've traveled in as is fuel. We
hired a Hyundai i20, fitted with metal studded snow tyres which
make it handle almost like a normal car on the frequently icy
roads. The i20 cost AUD700 for a 6 day hire. The car was
very fuel efficient, just as well, fuel was AUD2.20 per litre. Weather
services give you a good idea where to expect clear skies.
We drove out of Tromsø on 2
nights. The night we went to the Finnish border, we only got brief
glimpses of clear sky and there were no Northern Lights that night, got
back very tired the at 330am the next morning.
The other night, we drove to
a neighbouring island Kvaløya and were rewarded with a moderate
intensity display. Geoff Sims was there with Nelson Quan. They stayed
in Tromsø and were prepared and did drive long distances,
up to 5hrs, to clear skies each night they were there. They had more
success in terms of the number of nights and number of auroral displays
seen but Geoff told me all their time and energy went into the aurora
chasing. They basically slept, ate, drove and observed and not much
We stayed at “Yggdrasiltunet,”
a farm stay on Kvaløya, one of the many islands in the
region. The weather on the islands, is admittedly not as good as
inland however we were not there at the best time, our visit being
governed by the solar eclipse the following week. Maria, the
farms owner, told us that the best time for coming to stay, aurora wise
was November-December when there were more clear nights and long hours
We thought this farm
stay was perfect for us. However this style won’t suit
everyone. The cheapest accommodation on the property are small
cabins that have 2 small bedrooms, 8 sq m each with a double and a
single bed and a narrow passage between. The beds are attached to the
walls so you can store gear under the beds. Each room has
numerous power outlets for recharging all the batteries you’ll
These two rooms share
a small bathroom with one toilet and one basin and an entry/drying
room. The two rooms are rented separately NOK 800 (AUD140) ea per night
so if you don't hire 2 rooms, you'll share the bathroom with
strangers. The rooms are very small and you basically only sleep
in them. Then you have access to a lovely communal house where there is
a communal kitchen, bathroom with shower, toilet basin, and a large
living & dining room with large glass windows looking out on the
fjord. The guests are all very laid back and friendly and so the
communal thing worked well. In addition to the small cabins, there is
also a small apartment with kitchenette and if you have a bigger group
there is a cottage for hire that sleeps 4 & 5.
You can bring
groceries and cook for yourself or Maria can cook and provide meals for
approximately NOK130-300 per meal. Most guests mix it up between
self-catering and ordering meals. You just have to let her know
24 hrs in advance what you want. We ordered dinner one night and
cooked for our selves the rest of the time. The meal, a reindeer
stew with lingonberries was delicious.
It is possible to
catch a public bus out to the farm but carrying groceries, clothes and
equipment for a multi-day stay might be a bit of a handful. This
however avoids the cost of having a renta-car sitting there costing
money. If you do rent a car, there are some tourist drives around
the islands you can take during the days.
Another possibility is that you could catch the bus to the farm with
your luggage, have Maria cater for the first day, then catch the bus
back to the supermarket to do a shop the next day. Allow about 40
mins each way to the supermarket 30km away.
Most people staying at
the farm were there to see aurora so lights out around the farm at
night wasn't really a problem. There are a lot of street lights in the
village of Bakkejord, about 100m away on the road along the coast. The
farm is located up on a hill 40-50m higher than the street lights. At
the back of the property, this was not a problem. One night, a
Russian fishing trawler traveling up the fjord, shone its huge
spotlights on the shore and lit up the whole farm and the hills
surrounding it. But this was an isolated incident, most nights were quite dark.
As far as I can tell,
this property is unique in the region and I recommend this if you want
a more relaxing experience. On the clear nights, we cooked and ate a leisurely meal, then relax or even
nap until 9-10pm then walk outside the cabin to observe until astronomical twilight at 3am retreating inside to warm up any time we felt cold,
fall into bed. Contrast this to the nights we stayed in
Tromsø and drove out of town. There was a rush to have dinner,
hit the road for 1-2hrs, stay out in the cold by the side of the road
only having the car as a warm then a similar long drive back at 3:00am.
If you want to extract every bit of clear sky from your
stay, then stay in Tromsø and then drive out to clear
sky every night. Yggdrasiltunet makes for a relaxing enjoyable
stay balanced between observing and enjoyment of the beautiful
The farm is called
"Yggdrasiltunet" after Yggdrasil, the ash tree from Norse cosmology. It is located in the hamlet of
Bakkejord on the island of Kvaløya about 50km SW of
Tromsø. The host Maria is really lovely and I can
recommend this place to anyone if the communal accommodation style
suites your personal preferences.
A google search on "Yggdrasiltunet" will reveal links to booking engines.
