Re: ESA OPS-SAT

fyi, this info is visible on the ESA www pages, quote: "Soyuz Flight VS23 / Launch postponed. The new target launch date will be announced as soon as possible." See at www.esa.int. Currently the GNU radio live DVD (nowadays called live SDR), seems it is not updated as a package anymore. I need to pu...

Re: Geminiden 2019

fyi, I recorded some samples of the radio reflections (Ukraine, remote TV station), shortly after maximum in 15 Dec 2019. These all include head echoes, appear as "notch" in front of reflection. It was not possible to make any visual observations, due to clouds.... https://timokuhmonen.smugmug.com/N...

Re: Geminiden 2019

Hi, die Geminiden waren in Anzahl und Intensität denen von 2017 sehr ähnlich. Ich werde noch bis zum 17.12.2019 weiterbeobachten. Am Abend des 16.12.19 erhoffe ich mir ein kleines Nebenmaximum an hellen Sternschnuppen, so war es zumindest 2016, 2017 und 2018. Interested to hear, did you have a know...

Re: Geminiden 2019

In the central Finland, the weather forecast shows all time cloudy sky for this weekend :-( No visual observations, it looks so. I do have echoes receiver for 49.75MHz (TV station at Ukraine), but in generally it is now too late to count for Geminids. Usually I tend to take at least plus minus two w...

Re: 12.09.2019 14:52 Uhr MESZ Tages Feuerkugel & Meteoritenfall

nice to hear that meteorite were found :-) If it's weight is approx 2 grams, I assume then it is not classified as a smallest fragments, maybe a bit above that - am I right ? The winds tend to move smaller fragments more easily during freefall...

Re: Alpha-Monocerotiden 2019 Nov 22

I was not able to see visually Amo meteors. It was cloudy and raining a little bit. I assume the same conditions were for most parts of Finland also. I did have radio observation ongoing at 49.763070 MHz. I have been told this was the TV station on north-eastern part of Ukraine (10kW ERP). Time labe...

Re: Alpha-Monocerotiden 2019 Nov 22

Hi Timo! Which transmitters are You receiving on 49,xxxMHz? I think, the very last remaining analogue band 1 TV transmitters in Ukraine and Russia, have already ceased operation, or will be switched off very very soon?

Re: Alpha-Monocerotiden 2019 Nov 22

Anyone planning to make radio observations on this ? I had done preliminary check for few days and situation does not look good. There is only two possible stations that my receiver setup can hear in central Finland at 49.75MHz area. The raw radio data is not best quality then (each frequency - low ...

Re: Alpha-Monocerotiden 2019 Nov 22

I knew this topic, since Esko wrote about it on finnish astronomy forum. He said that it could be possible to detect it also on radio meteor echoes counting. If all goes ok, I could setup 49.75MHz receive system. Some of the frequencies I typically follow on Russia in that TV-band have disappeared (...

possible electric arc on meteor camera (high voltage line)

Couple of days ago, two records I noticed on my meteor camera. UFO capture regognised two bright flash on nigth sky. I assume these are originated from electric arc, and light is bounced back from lower clouds. There is nearby 20kV power distribution line. On that evening & night, there was windy co...
