El dijous 13 de Febrer els alumnes de tercer vam anar a l\u2019Observatori de l\u2019Ebre.<\/p>\n

Cada grup va fer la visita guiada amb un monitor. Vam poder con\u00e8ixer els \u00a0pavellons centenaris de sismologia, meteorologia i astronomia on hi vam veure els instruments actuals i hist\u00f2rics que contenen.<\/p>\n

Ens van explicar que l\u2019Observatori es va fundar el 1904 per la Companyia de Jes\u00fas per estudiar les relacions Sol-Terra.<\/p>\n

Fa 116 anys que est\u00e0 en funcionament!<\/strong><\/p>\n

<\/h3>\n

EL PAVELL\u00d3 S\u00cdSMIC<\/strong><\/h3>\n

Aquest pavell\u00f3 va ser la primera estaci\u00f3 s\u00edsmica de Catalunya. En el pavell\u00f3 hi hem vist el sism\u00f2graf Mainka modificat, que va estar operatiu entre 1942 i 1965.<\/p>\n

El pavell\u00f3 compta amb una exposici\u00f3 sobre els terratr\u00e8mols i la propagaci\u00f3 de les ones mec\u00e0niques per l\u2019interior de la Terra.<\/p>\n

\"\"<\/a><\/p>\n

En una columna de la sala de l\u2019exposici\u00f3 hi ha els registres de tres grans terratr\u00e8mols d\u2019arreu del m\u00f3n: el de la ciutat de San Francisco del 1906, el de Xile del 1960 i el de la costa de Tarragona del 1995.<\/p>\n

\"\"<\/a><\/p>\n

Avui en dia els sensors moderns d\u2019aquest pavell\u00f3 s\u2019uneixen a d\u2019altres estacions remotes per conformar la xarxa s\u00edsmica local.<\/p>\n

PAVELL\u00d3 METEOROL\u00d2GIC<\/h3>\n

El pavell\u00f3 i el jard\u00ed meteorol\u00f2gics contenen l\u2019estaci\u00f3 meteorol\u00f2gica i una exposici\u00f3 d\u2019instruments antics. L\u2019estaci\u00f3 meteorol\u00f2gica forma part de\u00a0l\u2019Agencia Estatal de Meteorologia<\/em>\u00a0(AEMET)<\/em>.<\/p>\n

\"\"<\/a>Tots els dies de l\u2019any un observador realitza, almenys 7 cops al dia, mesures de temperatura, humitat relativa, pressi\u00f3 atmosf\u00e8rica, precipitaci\u00f3, velocitat i direcci\u00f3 del vent, evaporaci\u00f3, insolaci\u00f3, cobertura i tipus de n\u00favols, visibilitat, aix\u00ed com<\/span>\u00a0l\u2019anotaci\u00f3 d\u2019aquells fen\u00f2mens que no es quantifiquen per\u00f2 s\u00ed s\u2019observen, com ara la pres\u00e8ncia de calima, boira, rosada, arc de San Mar<\/span>t\u00ed, tempesta, etc…<\/p>\n

Vam veure com un observador prenia les dades.<\/p>\n

 <\/p>\n

\"\"<\/a><\/p>\n

Aquestes dades s\u00f3n necess\u00e0ries per a la realitzaci\u00f3 de la previsi\u00f3 meteorol\u00f2gica.<\/p>\n

El recull de les mateixes al llarg de m\u00e9s d\u2019un segle s\u00f3n, avui en dia, un referent per a l\u2019estudi del canvi clim\u00e0tic.<\/p>\n

PAVELL\u00d3 ASTRON\u00d2MIC<\/h3>\n

\"\"<\/a>Aquest pavell\u00f3 cont\u00e9 el telescopi solar, un telescopi astron\u00f2mic utilitzat per a la divulgaci\u00f3 cient\u00edfica, una exposici\u00f3 sobre el sol i telescopis i instruments antics. Un dels telescopis antics va ser cedit per la NASA i va ser uns dels que es van emprar quan l\u2019home va arribar a la Lluna.<\/p>\n

Ens van explicar que, cada dia que les condicions meteorol\u00f2giques ho permeten, es fotografia la fotosfera del Sol amb un telescopi solar. Aix\u00ed es fa el seguiment d\u2019una de les manifestacions m\u00e9s caracter\u00edstiques de la seva activitat: les taques solars, que apareixen sobre la seva superf\u00edcie, varien de dia en dia i tenen una vida mitjana de entre dies i setmanes. Aproximadament cada onze anys el seu nombre passa per un m\u00e0xim. Les taques solars s\u00f3n regions del Sol amb intensitats de camp magn\u00e8tic milers de vegades m\u00e9s fort que el camp magn\u00e8tic de la Terra.<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

Vam poder veure com la c\u00fapula del pavell\u00f3 s\u2019obre per poder fotografiar el Sol i com es pot moure, girant sobre ella mateixa, per orientar el telescopi a la posici\u00f3 del Sol.<\/p>\n

Va ser una ll\u00e0stima que el dia estigu\u00e9s ennuvolat i no pogu\u00e9ssim veure les taques solars en directe amb el cel\u00f2stat!<\/p>\n

Cliqueu aqu\u00ed<\/a> per veure m\u00e9s fotos.<\/p>\n

En acabar la visita vam esmorzar a la zona que envolta el pavell\u00f3 s\u00edsmic.<\/p>\n

Vam aprendre molt i ens ho vam passar molt b\u00e9.<\/p>\n

Moltes gr\u00e0cies a tots els monitors!!!!<\/h3>\n","protected":false},"excerpt":{"rendered":"
