Sondehunting at winter! My first of the this year. -17 degC, recovered by skiing in the forest for an hour. Lots of snow. Everything at ground. Wooden spool with party-balloon and eco strings. Graw DFM17 #23063112.

This seems to be tradition for Latvian sondes. Latvian sondes all want to to flying perfect circle over a terrorist country. (Hint: this is actually GPS spoofing). This one was V2010811.

Yet another Latvia radisonde that hit pretty advanced GPS / GNSS jamming. Hint: radiosondes do not supposed to fly perfect circle for such time.

Quite advanced GNSS spoofing today on radiosonde V2010625. It was launched from Latvia but suddenly jumped and started to fly circle near Smolensk.
My guess this is related to Ukraines drone attack to Moscow oil refinery.

First sight of Vaisala RS41-SGPE ? Serial U2130583 sent from Vaisala office. https://www.vaisala.com/en/products/weather-environmental-sensors/upper-air-radiosondes-rs41-rs41-e-models #radiosonde #sonde #vaisala
Sonde Sunday (tm) find from field! #sonde #sondesunday #radiosonde #sondi #saapallo
Could this be first non-test-flight of Vaisala RS41radiosonde with the new PCB (RS424) ? https://sondehub.org/#!mt=Mapnik&mz=13&qm=3h&f=V2421144&q=V2421144

Last night midnight radiosonde (V1630925) in Finland had pretty abnormal ascent/descent speeds. It went up much slower than normally (probably wet or under-fill) and came down even slower most of the flight, about -2m/s. Our club receiver got first packet at elevation 0deg and last packet at -0.4 deg (334km) which is wayyy behind the radio horizon. #radiosonde #sonde #vaisala #weatherballoon
Sonde Sunday! Found four, searched for six. No deer keds (hirvikärpänen) at all. Autumn colors were nice. Fields were harvested so much easier to pick paths. #radiosonde #sonde #radiosondi #sääilmapallo
