Aurora was visible from Reykjavik city around 10:00 PM, we head towards National park to have a proper dark and avoid city light pollution. However the horizon was lit till 11:30PM due to late Spring.
Our bus went into Þingvellir National Park which has a prominent feature volcanic and tectonic activity, where the promontory creates an extraordinary natural amphitheatre. The site was the home of Iceland's parliament, the Alþing, which was first convened in 930.
Þingvellir National Park has the juncture of the North American continental plate and a smaller plate (approx. 10,000 km2) called the Hreppar Microplate (Hreppaflekinn)
We stopped at the tourist visitor centre overlooking at plates' junction down overlooking at lake and Iceland's parliament and in background is ice capped mountain.
Aurora activity reached at its peak by 11:00 and show was at max on mid-night time and lasted for long time. This day we had a KP index of 5.33+ and whole sky was lit by green colour and different hues of pink, purple, a bit of blue which is rare was visible to naked eyes. Dance was amazing and that is also captured in time lapse.
