Baray paimanay par shamsi bhark uthnay se zameen ke kuch hisson ko radio blackout mein doob jata hai

Media reports ke mutabiq, suraj par phatnay walay suraj ke dhabay se paida hone walay aik baray shamsi shuaalay ne dunya ke kuch hisson bakhshoosan behr-e-oqiyanoos ke ilaqe ko radio blackout mein daal diya.

National Oceanic and Atmospheric Administration (NOAA) ne 30 April ko aik intabaah jaari karte hue kaha ke AR3288 sunspot bohat taizi se barh raha hai jis mein aik ghair mustahkam delta class magnetic field hai. Solar Flare ko M7 class solar flare kaha jata hai.

Khalai mosam ki report ke mutabiq: “Ghair mustahkam sunspot AR3288 aaj 1 May ko 1309 UT par phoot para, jis ne aik mukhtasar lekin shadeed M7 class shamsi shuaala paida kiya. NASA ki Solar Dynamics Observatory ne intehai ultra violet flash ko record kia.”

“Bhark uthnay wali tabkari ne zameen ke mahool ke oopri hisson ko ainaa kiya, neechay sayaray par radio transmission ke mamool ke phelao mein khilal dala.”

“Bahera-oqiyanoos ke ard garad mariners aur him radio operators ne dhamaakay ke baad 30 minute tak 20 mega hertz say neechay signal ka nuqsaan dekha hoga.”

NASA ke mutabiq: “Suraj ke dhabay woh ilaqay hain jo suraj ki surface par siyah nazar atay hain. Woh taareekh nazar atay hain kyonkeh woh suraj ki surface ke dosray hisson say thanday hotay hain.”

Suraj ke dhabon ke qareeb magnetic field ki lakiron dhamaakon ka sabab banti hain jab woh dobara tarteeb pati hain, jis se shamsi shuaala nikalte hain. Yeh khula mein bohat ziyada tabkari chhorta hai. NASA ne kaha ke shadeed shadeed dhamaaka, tabkari jari karta hai jo yahan zameen par hamare radio mawaasilat mein mudakhilat kar sakta hai.

Space Weather dot com ne apne adad o shumar mein bataya ke mukhtasar taul-e-mauj ke radio blackout shumali aur shimal maghribi africa, junoobi america ke shimal mashriqi hisson bhi shamil hue.

Baray asar baher-oqiyanoos ke ilaqe mein mehsoos kie gaye. Blackout ke doran, 20MGZ ke radio signal shamsi dhamaakay ke baad kam az kam 20 minute ke liye zaaya ho gaye, data ne note kia.

Is ke ilawa, ek aur tashweesh shamsi toofan ke waqiat hain jin mein zameen ke maqnetic field se takraane ke liye khala se safar karte hue bari miqdar mein coronal mass ejection (CME) waqea hotay hain.

Un ke asraat geo-magnetic toofanon ko janam de saktay hain. Natijay ke tor par, satellite, mawaslat, internet connectivity, aur GPS mein khalla ya nuqsan ho sakta hai. Yeh power grid ki nakami ka sabab bhi ban sakta hai.

NASA ki solar and heliospheric observatory (SOHO) ki tasweer mein kissi bhi shamsi toofan ke qareeb aane ke bare mein koi hatmi saboot nahi milta jo zameen ke bashindon ke liye rukawaton ka baais ban sakta hai.
