1. TGEs and atmospheric discharges
Electric mill – EFM-100 short range CG lightning flashes, 38 (22) km;
StormTracker – 4 type of lightning flashes, up to 1200 km;
There is no coherence in EFM and ST distances!
ERL-10 With Coincidence Mode ?
LTS-2 GPS Timestamp ?
Why electric field and lightning detection is very important!

4. BOLTEK news
The Boltek BGW312 Ethernet Serial Server allows an EFM-100 and/or LD-250 to be remotely located any distance from the display computer using Ethernet to relay the data. Adding a long-range Wi-Fi Ethernet bridge also makes wireless operation possible up to several miles.
Storm tracker with LTS-2 GPS Timestamp accuracy – hundreds of nanosec; position ~ 1km

5. ERL-10 Lightning Relay Module for EFM-100
Coincidence Mode
With Coincidence Mode enabled a lightning strike must be
detected by both the EFM-100 and LD-250 for an alarm to
activate. Th is virtually eliminates false alarms that could
be caused by persons, animals or birds coming too near the
EFM-100 lightning sensor. Coincidence Mode is only applicable within the range of the EFM-100 (0-20 miles/0-32 km)

6. Experiment with 3 EFM-100 on Aragats in 2012 and in 2013.
Will be any progress?
