timestamp that is visible on Taivaanvahti observation title (together with date), that is current local time. Now it is UTC+3h (summertime). If there is timelabel on images, on most cases it is UTC time (not 100% still). This case was seen at 20:03 UTC.

just wondering, has anyone observed this ? I have not visited yet in Germany, I assume you still have more distant areas, that have less human created noises ? here is two samples of flying mammals sounds :-) http://timokuhmonen.kuvat.fi/audio/spectrograms/2020-08-20_zoom-H5_audio0002_spectrogram001...

Lieto / Finland at 6.9.2020 (both 3rd and 4th order bows) https://www.taivaanvahti.fi/observations/show/93429 Elmar, if referring third image in this observation, how did you see traces of possible (?) 5th order... I tried to increase heavily saturation and also put strong USM sharpening at GIMP. (...

Okay...some crude calculations from the limited image data available: hello, Did you make the analysis, with common known equations, or do you have a specific software or tools ? I know there is already more precise analysis done here in Finland. That data is currently available to only members of ...

The third image seems to show a trace of the 5th order, too.

Observation from Kurenpolvi, Finland (31.8.2020). There is only a small fragment visible (primary reflection bow) https://www.taivaanvahti.fi/observations/show/93277 fyi. I forgot to mention, that this observation has also weak secondary reflection bow (in addition to primary reflection bow). There...

fyi, Last night there was some magnetic activity. At least the SGO diagrams did show about 700nT changes. In central Finland, the sky was cloudy. No visual observations then... On hamradio band there would be possible to monitor aurora, like Swedish beacons (SK4MPI) of the radio reflections. I do no...

I did not get Perseids observed by best way, some cloud coverage prevented that during maximum time. One fireball I got couple of days after maximum. This was typically more bright than average. Bright spot on the left side (at wooden window frame) is the meteor light reflection from painted wood su...

..thanks for info. Estimates of the brightness are huge...

fyi. Looks like the auroral imaging season has started in Finland. I've missed this one last night.... I can see approx 250...300nT changes on the SGO magnetogram scale last night at 23 UTC https://www.taivaanvahti.fi/observations/show/92981 If NLC and aurora present at the same time, might be still...
