Southward propagating LSTID were detected last night over Europe by the @obsebre HF Interferometry method. Visit @Tech_TIDE Warning System for more details.
Federico Da Dalt from @rheagroup for @esa presents an introduction to the ESA S2P Space Weather Service Network and TIDs detection highly related with @Tech_TIDE products. Visit http://swe.ssa.esa.int/
Klaus Sievers, from @vcockpit, presents Satnav issues and Space Weather for aviation. Very interesting contributio for @Tech_TIDE. See http://techtide.space.noa.gr/wp-content/uploads/2020/06/Techtide_KS.pdf
The past Saturday 8 of June of 2019, SWPC/NOAA issued a warning for a minor Geomagnetic Storm, NOAA Level G1, at 18:47 UTC. Preliminary local K index of Ebro Station reached a value of 5 for the two consecutive three-hourly intervals 15 – 21.
The real-time HF-Interferometry method of TechTIDE detected a TID with a dominant period of about 125 minutes for the northernmost stations. The TID propagated dominantly southward and lasted from 20:00 (UT) of 8 of June to 4:00 (UT) of 9 of June.
The research group of Astronomy and GEomatics (gAGE/UPC) from UPC has analysed this specific event using the AATR index. AATR values (in TECUs/min) are shown in the attached figures to this post, for four different receivers (KIRU, ARJ, UME6 and VIS0).
As a conclusion, AATR index detects ionospheric activity during the last hours of day 159 (June 8th) in the auroral region.
