One hour measurements were taken in several locations close to the places in dip equator till a place with field variations less than 400 nanotesla is found. The installation requires metal free construction of two cement enclosures each of 1.2 x 1.2 x 0.5 m size pit, one for the magnetometer and other for the amplifier (about 5 m away from the magnetometer) in an open land with no house or a road with moving vehicles at least 200 m away from the location. Magnetometer to be aligned to get minimum errors on X, Y and Z components of the magnetic field. A cable from the amplifier will be 200 m long and it will be connected to a data logger inside a safe place in a house with electricity supply. A 4G router will be connect to the data logger for continuous uploading of data to MAGDAS world network. 12V car battery to be connected for continues uninterrupted uploading of data and the functioning of the instrument I power failures. Surge protectors (SPDs) to be fixed to the power supply to prevent lightning damages. A GPS instrument to be mounted on the roof top of the house and connect to the data logger for location and accurate timing of transmitting data. Once our data are supplied to the international network we can share data from other stations in the world. Data analysis will be done to study the magnetic field variation patterns and to understand the influence of solar activity on those variation<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"kc-elm kc-css-994655 kc_col-sm-6 kc_column kc_col-sm-6\">\n<div class=\"kc-col-container\">\n<div class=\"kc-elm kc-css-263723 kc_text_block\">\n<h2>Objectives<\/h2>\n<p><b>General Objectives<\/b><\/p>\n<p>The main objectives of this research program will be<\/p>\n<p>\uf0b7 Establishment of a geomagnetic filed measuring station in Sri Lanka close to the dip equator to provide valuable geomagnetic field data to strengthen the world data base by continuous streaming of data to MAGDAS world data base.<\/p>\n<p>\uf0b7 Study the position and movement of the equatorial electro jet over Sri Lanka<\/p>\n<p>\uf0b7 Investigate the relationship between EEJ variation and solar activity will be studied.<\/p>\n<p>\uf0b7 Understand the causative mechanism of counter electrojet and the parameters involved in the day-to-day variability of electrojet strength.<\/p>\n<p><b>Specific Objective<\/b><\/p>\n<p>\uf0b7 Establishment of a geomagnetic filed measuring station in Sri Lanka close to the dip equator to provide valuable geomagnetic field data to strengthen the world data base by continuous streaming of data to MAGDAS world data base while strengthening the postgraduate research capabilities within the field of space science in Sri Lanka related to geomagnetism.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n<section class=\"kc-elm kc-css-921721 kc_row\">\n<div class=\"kc-row-container  kc-container\">\n<div class=\"kc-wrap-columns\">\n<div class=\"kc-elm kc-css-682271 kc_col-sm-12 kc_column kc_col-sm-12\">\n<div class=\"kc-col-container\">\n<div class=\"kc-elm kc-css-71108\" style=\"height: 20px; clear: both; width:100%;\"><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n<section class=\"kc-elm kc-css-643684 kc_row\">\n<div class=\"kc-row-container  kc-container\">\n<div class=\"kc-wrap-columns\">\n<div class=\"kc-elm kc-css-84469 kc_col-sm-12 kc_column kc_col-sm-12\">\n<div class=\"kc-col-container\"><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Establishment of a geomagnetic filed measuring station in Sri Lanka NRC Grant No:&nbsp; &nbsp; 16-098&nbsp;&nbsp; Research Institute:&nbsp; University of Colombo Area of Research: Atmospheric Physics &amp; Lightning Physics; Astronomy Status:&nbsp; Ongoing Principal Investigator Prof. K.P.S.Chandana Jayaratne Department of Physics University of Colombo chandana@phys.cmb.ac.lk chandanajayaratne@gmail.com Summary The magnetic data acquisition system(MAGDAS) given to Colombo University on [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":250,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"class_list":["post-5722","page","type-page","status-publish","has-post-thumbnail","hentry"],"_links":{"self":[{"href":"https:\/\/www.nrc.gov.lk\/index.php\/wp-json\/wp\/v2\/pages\/5722","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.nrc.gov.lk\/index.php\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.nrc.gov.lk\/index.php\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.nrc.gov.lk\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.nrc.gov.lk\/index.php\/wp-json\/wp\/v2\/comments?post=5722"}],"version-history":[{"count":3,"href":"https:\/\/www.nrc.gov.lk\/index.php\/wp-json\/wp\/v2\/pages\/5722\/revisions"}],"predecessor-version":[{"id":5726,"href":"https:\/\/www.nrc.gov.lk\/index.php\/wp-json\/wp\/v2\/pages\/5722\/revisions\/5726"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.nrc.gov.lk\/index.php\/wp-json\/wp\/v2\/media\/250"}],"wp:attachment":[{"href":"https:\/\/www.nrc.gov.lk\/index.php\/wp-json\/wp\/v2\/media?parent=5722"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
