TO:  All GCN Notice recipients
RE:  LVC EARLY WARNING Notice type is available
DT:  30 May 2020

The LVC is now producing a new notice type.  They are adding the LVC_EARLY_WARNING
to the already available LVC_PRELIMINARY, LVC_INITIAL, LVC_UPDATE, and LVC_RETRACTION types.
Like all GCN Notices, this new type is available via the socket, email, and voevent methods.
And the voevent format is available via the 8 voevent servers as vetted or anonimous connection.

Briefly, this notice type is now the earliest in the time sequence of LVC notices
for for L-V GW events.  Please see LVC User's Guide at  https://emfollow.docs.ligo.org/  (ver 16).

L-V will be producing this notice type in a week-long experiment run starting ~ June 9th.

If you want to receive this notice new type, please return this email with a simple statement
something like "Yes, I want this new type" (along with the attached copy of your current configuration
which is how I will identify you).  And your configuration will have the LVC_EARLY_WARNING
added to list of notice types you receive.
