When will BYD fix this scaling issue for all type of different power outputs?
I never see the redline there because the dial scaled for AWD power output... So 170 KW is a little bit above eco blue to power red.
I'm a photographer from Türkiye, not a local. I've made 11 winter trips north since 2013, most of them to Northern Norway in February–March. The same worries come up here every autumn, so here's what the numbers say for Tromsø specifically.
Kp is rarely the problem. Tromsø sits at about 67° geomagnetic latitude, under the auroral oval. Around Kp 1 is enough for a glow low in the north, and around Kp 3 for aurora overhead. In the last 12 months the planetary Kp reached 1 or more on 360 of 365 days and 3 or more on 228 (GFZ's definitive record). Kp is also a three-hour planetary average, so don't stay in on a clear night because an app says "Kp 2". My Lyngenfjord frame in the book was shot at Kp 2.67, with the curtain overhead.
Cloud is the problem. Tromsø is coastal, and the weather comes off the sea. On ten years of reanalysis data (ERA5, 2015–2024), the area averages about 80% cloud cover in October, January and March, and 86–88% in November and December. Averages hide the gaps, and the gaps are what you're hunting, but it's why one-night trips strike out so often. Inland, behind the mountains (the Skibotn valley, or Kilpisjärvi on the Finnish border about 2.5 h away), it's often clearer when the coast is socked in. That's where chase tours go on bad nights. If the coast is clear, nobody needs to drive anywhere.
Darkness sets the season. It's dark enough for a bright display from about 1 September to about 10 April, and fully dark from mid-September to late March. Polar night (27 Nov to 15 Jan) means no sunrise, not 24 hours of dark. There's blue twilight around midday, and in mid-December it's dark enough to watch from about 15:30 to 07:45.
The moon matters less than people think. A full moon washes out faint aurora, not a strong one. If your dates are flexible, this season's new moons fall around 10 Oct, 9 Nov, 9 Dec, 7 Jan, 6 Feb and 8 Mar.
More nights beat a perfect night. A front can sit on the coast for two or three days, so four or five nights give you several separate shots at a gap. If you can, keep your tour night movable and pick it 2–3 days out, when cloud forecasts start to mean something.
Be a good guest.
Disclosure: I turned my aurora book into a free website, Chasing Pink. Its Tromsø page:
No account, no email, no ads. The site also sells the printed book and prints, but nothing here links to that. It's odds, not a guarantee, and it can't see through cloud any better than Yr can. Locals especially: if anything is wrong for Tromsø, tell me and I'll fix it.
Give it a try. I only focus on solid trance releases.
Comment if you have source request.
I seem to remember that this CD was made available for free in April 2006 by the talented Sensorica. It's one of those rare albums that successfully combines a variety of genres, from uplifting to psychedelic trance and from progressive to melodic. Discogs claims that it was released in February 2007, but I haven't been able to locate the album anyplace else. I'm sure you'll like hearing it.
