The distance of the lightning strikes is way off?

The local weather radar is showing lightning strikes about 30-50 miles from my location and the Acurite shows them as 5-12

Strikes 30-50 miles away are outside the 25 mile range of the detector, so they probably aren't what is setting it off.

Thanks for the reply. I thought of that, but it's been up for a couple of weeks and no strikes until today when there was lightning for the first time.  And lightning has moved out of the area and the strikes have stopped registering...too much to be a coincidence,

Steved13,

I believe your sensor is reporting what it calculates as distance to a storm front, which is different from distance to a lighting strike.

Hmm, it is showing at the bottom of the display as a lightning strike.  It shows the count on the left and the distance of the last strike on the right.  At least I'm pretty sure that's what it means?  It is definitely the lightning strike sensor window?

I'm pretty sure the sensor uses a chip receiver/signal processor known as AS3935 "Franklin", like Ben and his kite.

George N. opened up a sensor last fall and posted that designation on wxforum.net .
It would be great if he joined this discussion with what more he knows about this device.

That chip uses a proprietary algorithm to assess signals from lightning strikes, calculate their energy, infer distance to a strike, and construct an estimate of distance to the storm front, which is then presented to the user.

Pretty neat!

postscript: I thought this was so sweet I just bought a portable detector for use on the lake.

Hello Everyone,

The lightening detector detects electromagnetic fields.It will show the distance to a lightning strike. Steved13, make sure the detector is placed at least 3 feet (.9 m) away from electronics that may cause interference (such as TVs, microwaves, fluorescent lights, computers, laptops, refrigerators, cordless phones, USB-powered devices like webcams & keyboards, car electronics, etc.). If you still believe the lightening detector is not functioning as designed please contact our AcuRite Loyalty Team at 262-249-3259. Thank you.
