Plan for the Field Trip Week
Plan for the Field Trip Week
We will arrange a Field Trip Week in 2025 to do a collective effort and set up equipment all over the valley.
We want to dedicate an entire week to field observations.
Fred Pallesen - CEO of Project Hessdalen
We are in the planning mode!
Do Sign up to get information when we have meetings or new information to share about our plans for the Field Trip
We need your help to plan this!
Do you have any instruments we could deploy in the valley.
Can you help us get equipment or funding to buy more cameras, sensors and computers?
Do you want to help in organizing this event?
When
When
From August 30 to September 7
The team will meet the first week of September
September is a good time for a Field Trip:
Not too cold, but starting to be darker.
Where
Where
Hessdalen, Norway
The "easiest" is to travel via Trondheim.
The valley is some hours south.
How
How
By car, bus or train
Rent a car in Trondheim.
Then you can get around in Hessdalen

- or check on airbnb.
Meeting minutes: from February 5th (public meeting)

The Field Trip Week 2025 will be
from August 30 (Saturday) until September 7 (Sunday).
This year, people must take responsibility for their own transportation to and from their accommodation and to the mountain hikes they choose to go on.
Unless you are volunteering for a specific task that requires your presence all week, people are welcome to come for just a weekend or a few days.
We will coordinate where and when we meet and where the different groups go and what they do - on discord
We are planning for cameras that can record a 360 view time lapse for 5 days (one image every three seconds) in a number of locations.
See "5 days time lapse" below for details.
We are planning for trail cameras / wildlife cameras along the river.
See "wildlife cameras" below for details.
We hope to test some Scientific Cameras ...
We should try to set up some Mupas systems in some cabin or houses (where there is power and internet)
See "Mupas systems" below for details.
We should try create a Mobile Mupas systems to be place out in the wild (with power from solar panels and batteries and a mobile internet connection)
See "Mobile Mupas systems" below for details.
Meeting minutes: from February 12th (internal meeting)
Meeting minutes: from February 12th (internal meeting)
We should prioritize equipment that could operate all year, not only during the Field Trip Week - because a lot of the work will be to create a weather proof casing with a power station (solar + battery) and internet connection.
Why not just set this as a goal.
Then we had a number of stations: rooftop / backpack / mountaintop - that we hope to build and test - before we get to the valley (at home) and then stress-test during the field trip.
This will be presented during the next Monthly Status Meeting ...

Objective
Objective
To develop a modern Anomaly Detection System (ADS) for Project Hessdalen by deploying compact, off-grid measurement stations with all-sky cameras and environmental sensors to detect and categorize anomalous events in real time.
Background
Background
Project Hessdalen has operated an ADS at the BlueBox in Hessdalen since 1998. In September 2024, the system was upgraded with two Enhanced Night Color 4K cameras. The next field trip in September 2025 will serve as a testing ground for new cameras and sensors.
Phase 1 (2025): Proof of Concept (PoC) Plan
Phase 1 (2025): Proof of Concept (PoC) Plan
The PoC aims to develop an effective ADS by deploying:
Mini BlueBox: A small, off-grid hub featuring a 24/7 streaming all-sky camera, environmental sensors, and a microcontroller for real-time anomaly detection.
Mobile MUPAS: A variant of the Mini BlueBox housing a MUPAS system for deployment on mountaintops with 4G/5G coverage.
Both units will transmit data to the cloud for storage, monitoring, and AI-assisted categorization.
Locations for new equipment
Locations for new equipment
These are the locations we would like to put out cameras that can record for at least 5 days - during the Field Trip:
We know that some of these locations are within the Forollhogna national park - and we need to get permission to put out the equipment. We'll find out!

New Anomaly Detection Systems
New Anomaly Detection Systems
All systems, whether temporary or permanent, require
waterproofing, condensation management and temperature control.
Why not make permanent solution?
We initially planned to build small systems to record a five-day time-lapse of the sky during the field trip. However, since any system requires waterproofing, condensation management, and temperature control, why not design permanent stations that can remain on mountaintops year-round?
Instead of dismantling everything after just five days, we could invest in long-term solutions. While permanent stations would require additional equipment—such as solar panels, batteries, and a larger enclosure—they would eliminate the need for frequent redeployment. Although carrying the equipment up the mountains, securing it against wind and weather, and performing maintenance would be demanding, the effort could be justified by the long-term benefits.
The added weight of a permanent setup might require just two additional team members or an extra trip to transport everything. Given the advantages of continuous data collection, this could be a worthwhile trade-off.
Off-Grid Power & Internet Hub
Off-Grid Power & Internet Hub
We need different configurations for the ADS stations: they all need a solar panel and a battery and a 4G/5G internet router. Some need more power - some less. We need to calculate the energy needed - and build some Off-Grid communication boxes.
Off-Grid Mini Hub
Off-Grid Mini Hub
The Mini Hub should be able to work as a waterproof enclosure for a microcontroller with a number of sensors sending data over the internet

The Mini Hub should work as an enclosure for a MUPAS system that will work as a mobile system.

Hidden in a "rock".
Is it possible to put sensors in a "rock" with solar panel - to work all year? (or close to)
How can we create this?
What sensors do we need:
Compass
Humidity
GPS
(what more?)
We would need help to
make this system
store the data
analyze the data
make an alert system
We could make this kind of "rock" ourselves, by using some boxes, chicken wire, concrete and creativity!
Goal: Test scientific cameras
Goal: Test scientific cameras
Downsides of current cameras: compression and dynamic range
We have and can get some scientific cameras - but we need to figure out how to build a waterproof enclosure and cable mount.
We need to attach the cameras to the mast and test the software for the cameras in the Blue Box.
We need to evaluate the best camera setting and create and test a trigger system.
