We present 57 photometric epochs of superluminous SN 2017egm in NGC3191, covering the period of 285 days, and 36 epochs of peculiar object AT 2018cow, for which observations lasted 69 days. UBV RI photometry was carried out with 7 telescopes at 5 locations, including the 2.5-m telescope at the Caucasus Mountain Observatory of the Sternberg Astronomical Institute. The light and color curves of SN 2017egm were compared to several well-studied objects of similar type. The light curves of SN 2017egm show definite undulations: a shoulder at phase 114 days past maximum and a plateau lasting for a phase interval 155–235 days. We determined the basic parameters of the light curves for SN 2017egm and AT 2018cow: dates and magnitudes of maximum light, rates of decline at different stages of evolution in different bands.","PeriodicalId":50617,"journal":{"name":"Contributions of the Astronomical Observatory Skalnate Pleso","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45535126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we carry out by utilizing the distance equation with providing some basic descriptive statistics for both apparent and absolute magnitudes, the distances of some open clusters (i.e., Hyades, Pleiades, IC 2391, Koposov 12, Koposov 43, NGC 1348, NGC 2112, NGC 4337, SAI 24, and SAI 94) with the assumption that all members N are scattering around a mean absolute magnitude in a Gaussian distribution. Our numerical obtained results are in good agreement with previously calculated values. In the second part of the paper, we have calculated the luminosity function of Hyades open cluster by Salpeter’s normalized function Ψ( M V ) due to frequency distribution function Φ( M V ), on this way, we have got a very significant relationship between them with absolute magnitudes M V (i.e., the linear correlation coefficient ∼ 0.995), and the error analysis are also given.","PeriodicalId":50617,"journal":{"name":"Contributions of the Astronomical Observatory Skalnate Pleso","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43920679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The improvements of classical CCD are moving toward improving quantum efficiency in UV, development of the new anti-reflection coatings and multilayer UV filters with enhanced red leak suppression. CMOS with a very small pixel (3-5μm) of more than 20 Mpixel format allows to improve sampling and to increase the price/performance ratio of a small aperture telescope.","PeriodicalId":50617,"journal":{"name":"Contributions of the Astronomical Observatory Skalnate Pleso","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49311550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A comparative analysis showed a significant increase in the number of registrations due to the processing of meteors that are weaker with signal-tonoise ratio. The seasonal and daily dependencies of the meteor number for the period 2016-2019 are given. The obtained distributions of entry meteor speeds and their dependencies by seasons and heights of meteor trails are separately considered.

Similar ACP spears have all stars with planetary systems in the Galaxy. Since such stars are part of the open clusters population, they scatter and form the ACPS spears. In this paper, we performed numerical modeling of the ACP and ASPC spears and estimated their parameters, such as length, width, and time of formation.","PeriodicalId":50617,"journal":{"name":"Contributions of the Astronomical Observatory Skalnate Pleso","volume":"10 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70009902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
