The detection of traveling wave disturbances manifested in the 630 nm atomic oxygen airglow caused by the effect of the SURA facility was the goal of this analysis. Except for two cases, no differences were found between periods with and without the effect of radio emissions from the SURA facility on the ionosphere. On August 7 and 10, 2021, weak wave structures similar in form and subsequent behavior were detected; they were moving in opposite directions from the SURA facility site with a length of at least 400 km. On August 7, 2021, the estimated front velocity was ∼104 m/s to the southwest and ∼127 m/s to the northeast. On August 10, 2021, the front velocity was ∼71 m/s and ∼142 m/s along the same directions, respectively. No such structures with such behavior were recorded by us before. The complex analysis of the heliogeomagnetic and ionospheric data for the experimental session in August 2021, including the days when traveling wave structures were detected, is presented in the paper. Unfortunately, we cannot unambiguously associate the detected traveling wave structures with the pumping regime of the SURA facility at that time. The source of these wave structures is still unclear.</p>","PeriodicalId":46751,"journal":{"name":"Atmospheric and Oceanic Optics","volume":"37 1 supplement","pages":"S199 - S207"},"PeriodicalIF":0.9,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Levin and other scientists. The results significantly contributed to hydrooptics and ensured progress in the development of technical means for observing underwater objects and the aquatic environment.
