[vsnet-chat 306] Re: Early SN detection via neutrinos

G'day Alec (and vsnetters..),

A Supernova Neutrino Alarm?  An excellent idea!


My comments:

How accurate (and precise) a position would be provided by this
system?  Would an Alarm Report read "possible SN in Centaurus" or
"possible SN at RA 13h19m11s +/-5s  Dec -55d20'09" +/-02"  ?

Would the system give any indication of expected visual magnitude?  Even
an approximate guess would help; for example, a 50000-neutrino pulse
should be a brilliant SN, but a 50-neutrino pulse would warn us to get
the binoculars and starcharts out...

How many hours/days between the neutrino pulse and the visual outburst?
Or is this piece of information one of the things you hope to discover
from this project?


You should post any Alarm Report into vsnet-alert and the International
Supernova Network (isn@mbox.queen.it).  A lot of astronomers and
institutions subscribe to these two mailers.  On numerous occasions,
these have spread some vital news worldwide before any official messages
from CBAT.

As for notifying me, a personal email or a posting to vsnet-alert will
suffice.  Like many vsnetters, I don't have a 24-hour Internet link but
I do collect my email regularly.

SN Eta Carinae would do me nicely.  I have a pair of sunglasses within
reach... <g>
