• Using the free TeamSpeak software: Download from here and install the software, preferably in advance. Please use either an anti-echo USB speakerphone (e.g. a "Phoenix box") or headphones to prevent echoes. At the beginning of the telecon, connect to the server at zam.mit.edu and use the password la$er. (Note to LVC members: this is not the usual LVC telecon server.) Once you are connected to the server, drag your name down to the "LV-EM Forum" channel. For more details and usage advice, see TeamSpeakInfo.
• Telephone: Dial the access numbers 1-800-704-9804 (toll free in the US; possibly accessible toll-free via skype from outside the US too) and internationally 1-404-920-6604 with participant code 8295093# . To mute/unmute your line, press *6 .Please note this telecon, agenda, and minutes are not password-protected.

==> Announcements:
Earlier LVEM call @08:00 UTC -- look out for minutes
Monthly OpenLVEM telecon on 3rd Thu of each month;
no meeting in March because of the Town Hall meeting @MIT

==> Town Hall meetings
Walked over wiki @ https://gw-astronomy.org/wiki/OpenLVEM/TownHallMeetings2018
OpenLVEM is in effect as of January 2018; Formal announcement by LIGO-Virgo spokespersons imminent
Survey reponses ~80; Boston, MA March 16/17 and Amsterdam, Netherlands April 12/13.
Please note change of venue in Europe from Italy to Netherlands.
Town Hall registrations @ https://openlvem.mit.edu . Please indicate your attendance ASAP.
Structure of meetings:
(1) LIGO-Virgo status
(2) short presentations from participants
(3) policy on OPA: rate of events, latency, event profile
(4) astronomer preparations
(5) science driven MOUs and collaborations
(6) standardizing records from astrnomical observations
Stefano V: will there be remote participation to the meeting?
Erik K: will do our best but can't guarantee at this point
Steven S: agenda is good; most important is #3.
Need to understand what can be provided and what is wished to be provided.
Steven S: #5 is also valuable. Avoid short presentations on what participants are doing.
Suggest short pre-meetings/parallel meeting to think and discuss on #5.
Erik K: break-out idea for discussing science-based MOUs/collaborations is a good one
Marcos S: will be good to organize science groups under the LVEM umbrella.
These should be separate for the main EM followup of OPAs
Enzo B: #3 and #5 items will need a lot of time
Brad C: echo Steven's comments
Erik K: shall we press ahead with these science groups now or wait
Steven S: it can wait for formal structure but good to get the discussion going 
Erik K: any presentation from the astronomy side in the way of
Colleen: need status/update on the instruments and rates of events

==> O1/O2 event profile discussion:
Added information in O2: Distance information, EM bright classification
Steven S:  p_astro is a very useful thing-- will you provide that?
Erik : most likely
Steven S: OPAs will be at FAR < 1/100 years. What is the rationale for that?
Erik K: slides shown are from previous meetings/statement is a boiler plate one
Erik K: item is in discussion within the collaboration
Erik K: a question for the astronomer colleagues:
what is your preferred FAR for a system that is NOT classified as binary?
Steven : 1/month -1/2mon ; it will depend on the facility
Peter J: second Steven's argument; overall hard question to answer
Enzo B: what was the rate of O2
Erik K: 1/2mon
Steven S: will there be new pipelines producing alerts?
Erik K: to zeroth-order, no. The same 3 CBC and 2 Burst searches that reported
alerts over O2 will continue over O3 too. Please note Bayestar and LALinference
are follow-up pipelines that measure from the data extrinsic and intrinsic source
parameters, most notably the 3D skymap.
