Re: Druckwelle der Eruption des Tonga-Vulkans in Deutschland messbar
FYI. I attach sample of my images here, from central Finland. Needed to use database browser (SQLite) for this, since BlueAstro USB weather stick program does not allow custom plots. There data is saved to db3 -format. Both weather sticks are saving measurements to same database. In my example I hav...

Re: Druckwelle der Eruption des Tonga-Vulkans in Deutschland messbar
FYI. I have included my set of data here, atmospheric pressure measured at Vesanto, central Finland. Although the measurement is made inside, I assume the small atmospheric pressure increase (or decrease) should be still the correct one...

Interesting thread here... I do have had my two BlueAstro USB weather stick measuring atmospheric pressure (on central Finland). There is two sharper "notch" visible . I'll took a screen captures next... One observation is already documented on Taivaanvahti (Artjärvi, Finland) https://www....

Re: (Sammelthread) Polarlicht-Vorwarnungen 2022
fyi. There is some glow visible on my meteor cameras (Vesanto, at central Finland) on low northern horizon. Cannot be yet sure, if that is aurora or not. Moonlight disturbs a bit. I have put a timelapse sequence active on the meteor camera for this night...

Re: ? Polarlicht 2022-01-08/01-09
fyi.
View from my fireball camera (Watec 910, peak hold image) yesterday at central Finland. The time label is in UTC format. Auroras were also clearly visible by naked eye. I was not all time outside, so it could be possible that moment of the brightest auroras had been missed.

Re: Frage zu "!"-Bildfehlern
I do not have full 100% explanation that particular image, since I do not know your camera system. Assume you have Nikon camera, what model is it ? I have seen straight lines, on the video clips of my fireball camera (Watec 910HX, 25fps, monocrome sensor). Line (or dual lines near each other) are on...

Re: Geminiden und andere Meteore Dezember 2021
thanks a lot for info. Looks like a work is ahead with google translator :-) Also here HDSDR used, is not very stable. That most propably is not HDSDR fault, I assume Ext IO DLL (between device drivers and HDSDR) is not fully compatible with HDSDR. At least that Ext IO DLL has possibility to route I...

Re: Geminiden und andere Meteore Dezember 2021
Hello, for those using HDSDR ansd SpectrumLab - how do you define the calculation settings in SpectrumLab, so that it could detect signal based on amplitude going above pre-defined level ? I have a both programs running. Could be nice to try also, since HROFFT is not stable on long term use in my PC...

Re: Geminiden und andere Meteore Dezember 2021
fyi, Geminds observation here on central Finland with meteor camera has been limited. There was longer duration cloud coverage. Yesterday evening was clear at time AKM meeting. Following night seems also clear sky. Bright moonlight could cause weak meteor trails to disappear on camera...

Split sun pillar, Taivaanvahti (Inari / Finland, 12.11.2021)
I have not seen similar like this before... Any ideas what could cause splitting of pillar? https://www.taivaanvahti.fi/observations/show/102316 In practise it may be possible, that in the middle of sun disk there is dense cloud blocking sunrays? Would be practical reason ? Also the sun is not a poi...

Re: (Sammelthread) Polarlicht-Vorwarnungen 2021
FYI. For visual aurora observations, weather conditions do not look good at central Finland. Sky is cloudy for this night, also the same forecast to next night. I am at least following the RF aurora propagation at 6m band, so I have more chances to see (or hear) something :-) EDIT1 (30.10.2021, 18:4...
