April 4 TGE – mostly electrons! Ne/Ngamma ~ 2!!!! 3 hours long TGE at low energies STAND1 MAKET – under deep snow! EFM 100 GAMMA – very large disturbances IS it possible to make energy spectra from ASNT1 and NaI3? Why ASNT 10 do not show signal, and ASNT 01 show 5 sigma?

MAKET EFM and STAND3 upper

STAND1 SKL and STAND1 MAKET under the snow

Long-Long TGE: STAND1 SKL

MAKET 5 and 60 cm thick

Cube with/without Veto

Cloud-to-ground Lightning at 16:00:45 Surge of the count rate of 3 cm STAND-SKL after lightning at 16:00:45 is = 91; Equivalent to 91/27 ~ 3.4σ

Lightnings detected at Aragats and Nor Amberd at 16:00:45 and 16:08:15 Distance to first lightning by MAKET and SKL 5.5 and 10.8; from Nor Amberd – 14.8 Distance to second lightning by MAKET and SKL 5.9 and 10.7; from Nor Amberd – 8.8 Yerevan – 14.8
