Neutrino May day 13 Madison USA2+ 26 events
If 10-12 of the 28
events are atmosphericthan the 7 muon tracks must be mostly of those family.. But why the remaining 18 or 16events are muon free..?

Somehow the 28 are puzzling
• No GZK..otherwise peak at EeV no PeV
• No Fermi power -2: more PeVs events otherwise..NEED of a CUTOFF
• No Prompt neutrinos: too many and too few muon neutrinos: expected 1:1..we have 1:4
• No Extragalactic or Galactic points..but
smeared areas ..maybe like TeVs ones
Puzzling muon paucity or absence

The Flavor Sorpasso revolution
• The high energy atmospheric neutrinos are ruled by muon ones leading to tracks
• CC Electrons, CC Tau and NC neutrino may lead to spherical shower events: Cascade Shower, a ball of lights
• The 28 events are 21 Cascade (Shower)• While only 7 muon tracks: so most
atmospheric ones..making muon poor the extraterrestrial ones

Atmospheric neutrino Pollution makes life impossible for other 18 neutrino
• If among 28 events 10 are polluted muon or muon neutrino then: all 7 tracks are among these 10 atmospheric ones
• Assuming an oscillated neutrino flavor 1:1:1 Not the relic 18 where most or all are electron or tau
• The probability of the muon non appearencenon appearence in 18 events is: 0.00067..if just one muon is extraterrestrial the probability is 0.1%...
• Therefore IT IS MUCH BETTER TO IMAGINE ALMOST ALL neutrino as extra terrestrial:
• But we need A SHARP CHANGE in spectra• Already from 100 keV energy..

Conclusions
• We are seing a new Neutrino Astronomy • Puzzled by the flavor transition..Our solution assume
already at 10 TeVs an extraterrestrial presence• The Galactic origin is favored by mild correlations in
maps (UHECR,Neutrinos)• Extragalactic component may overcome CMB opacity
and it may accumulate because a better visibility than gamma PeV photons;
• Vela, Cygnus X3, Galactic Center maybe first sources• UHECR doublet correlation with W49B and W44 rises• Horizontal muon tracks conting may calibrate
atmospheric neutrinos• Tau airshowers in horizons may see first airshowers

About Analemma
• Exposures were made at the same time of day (9:00am local time), capturing the Sun's position on dates from January 7 through December 20, 2003. The multiple suns trace an intersecting curve known as an analemma. A foreground base exposure of the Temple of Apollo in ancient Corinth, Greece, appropriate for an analemma, was digitally merged with the film image. Equinox dates correspond to the middle points (not the intersection point) of the analemma. The curve is oriented at the corresponding direction and altitude for the temple, so the Sun's position for the September equinox is at the upper midpoint near picture center. Summer and winter solstices are at analemma top and bottom.

Where is the answer?
• If the extraterrestrial highest hundreds TeV neutrinos are also muons then, around the cubic km, muons must be born and they (if inclined or horizontal) must cross the detector at a rate of 20-40 each year: Just at horizons—they maybe a meter of flavor
• The atmosphere and the Horizontal ice itself maybe source of horizontal.upgoing air-shower at a rate observable as Cherenkov lights in Antartic dark nights
