Some cool lightning facts

Some Cool Lightning Facts


Lightning strikes

Lightning Strikes


What are vlf and elf waves

What are VLF and ELF Waves?

VLF waves recorded at Siena College


Vlf waves at about 24 8 khz

VLF Waves at About 24.8 KHz

Amplitude (Peak-to-Peak)

 Radio Signal 

1 Cycle = 7.5 Miles (12 KM)

 Distance traveled over time 

How to make this Computation?

Speed of light:c = 186,000 Miles/Sec (300,000 KM/Sec)

Frequency:f = 24,800 Cycles/Sec

Wave Length: = c / f Miles (or KM) / Cycle


Lighting vlf studies in antarctica

Lighting-VLF Studies in Antarctica?


Ground based vlf monitors

SID

Low Cost (~$150)

Single band

1 sample/5 seconds

Preassembled & tuned

Students build antenna

Available free to underserved schools from Stanford University.

AWESOME

Moderate cost (~$3000)

Broadband; sample rate of 100kHz on each channel

Capture ELF/VLF frequencies

~30 Hz - 50kHz

Dual use system:

Daytime: monitor solar activity

Nighttime: monitor atmospheric phenomena (e.g. lightning)

So sensitive that nearly any signal above the ambient Earth noise floor can be detected

Data useable for ionospheric and solar researchers

Ground-basedVLF Monitors

Winter in NY 

Summer in NY 


The firefly satellite mission at siena

Firefly will employ on-board and ground-based VLF measurements.

The Firefly Satellite Mission

  • Student Profile

  • Undergraduate physics major Robert Carroll was the student lead on the lightning photodetector design.

  • A primary task was to calculate the field of view of the photodetector and the overlap function.

  • Minimum and maximum field of view were calculated based on the geometry of the photo detector and collimator.
