Koul 1 Lalmani (drlalmani@yahoo.com) 1 Physics Department, National Institute of Technology, Hazratbal, Srinagar, Kashmir (INDIA) <p style="text-align: justify;">Different types of whistlers and VLF emissions recorded during day and night times are reported at our newly set-up ground station Srinagar (geomag. lat. 24^o 10^/ N). Dispersion analysis of whistlers recorded during March- June 2009 shows that the dispersion of the whistlers recorded during daytime is higher than those recorded during nighttime. Daytime whistlers are found to appear during very restricted hours in the late afternoon. On the other hand, nighttime whistlers are observed over a wide time interval but generally peak in the early morning, and their dispersion is widely distributed. Further our data analysis shows the occurrence of different types of VLF emissions during day and night times.</p> https://ultraphysicalsciences.org/paper/1167/ Experimentalof observations Whistlers and VLF emissions at Srinagar
