[igrav-steering] Amaldi14 and iGrav satellite meeting

Wed Jun 2 18:23:42 UTC 2021

I was thinking it was time for another meeting to work on meeting details anyway so maybe we should get on a call next week and flush out what we need to do. I have put together a doodle please.

Hi all

Sorry for the multiple emails.  I’ve had a further reply from Susan Scott…

It looks like those last two blacked out rectangles in the Amaldi programme are going to be needed for parallel sessions, since there were so many abstracts submitted. (Susan had mentioned this already in a previous email and I missed it).

So we should think about when to shift our proposed IGRAV slots too, in order to avoid Amaldi.  (At least now we know how the Amaldi calendar is calibrated).

Any suggestions?

Cheers
Martin

Hi all

I had to iterate with our Amaldi colleagues to answer Chris’ question, mainly because I don’t think I phrased it clearly enough first time…

I think it boils down to this.

In the programme at https://www.amaldi14.org/program.html there are five columns, headed 19/07, 20/07, 21/07, 22/07, 23/07.

In the 19/07 column, for example (containing Session 1, in yellow) we want to know if this session take place on 19/07 in Melbourne, Tokyo, Mumbai and Rome, and on *18/07* in New York and Los Angeles.  (Chris, did I get that right? This is what I’ve re-asked Erin et al).

I was fairly sure that the above is the case, since e.g. Block 3 (Session 2, in orange) on 19/07 then really does take place on 19/07 in all the timezones.   Susan Scott has just confirmed that is indeed the case.

So now we know that the calendar is calibrated to Melbourne.  Hence Block 1 takes place on the previous day to the date listed at the head of the column in Mumbai, Rome, New York and Los Angeles, and Block 2 takes place on the previous day to the date listed at the head of the column in New York and Los Angeles.

So does that mean our proposed IGRAV slots would be the following? (Again please correct me if I’ve got this wrong…)

  1.  During Amaldi Block 2 in the Thursday 22/07 column (this is a black rectangle so doesn’t clash):

This means it would take place 2300-0100 UTC (i.e. starting on Wed 21/07 UTC); 0100-0300 CEST on 22/07;

1600-1800 PDT on 21/07; 0900-1100 AEDT on 22/07.

  1.  During Amaldi Block 1 in the Friday 23/07 column (this is also a black rectangle so doesn’t clash):

This means it would take place 1500-1700 UTC on 22/07; 1700-1900 CEST on 22/07; 0800-1000 PDT on 22/07;

0100-0300 AEDT on 23/07

The above two IGRAV slots don’t clash with any Amaldi slots.

Cheers
Martin

Hi Martin,

The proposal (which is in the current version of the registration form<https://forms.gle/EVq3kBRqunJ6oCUB7>) was that we meet:

Thursday 22 July 2021 Block 2:  2300-0100 UTC (0100-0300 CEST / 1600-1800 PDT / 0900-1100 AEDT)
Friday 23 July 2021 Block 1: 1500-1700 UTC (1700-1900 CEST / 0800-1000 PDT / 0100-0300 AEDT)

Based on skipping Amaldi sessions https://www.amaldi14.org/program.html

However, there's an issue of timezones and dates - specifically whether the date is for Australia (AEDT) or UTC, as those are different. If the dates are for the time/date in Melbourne, then the UTC date is actually the day before - so in Europe & North America the sessions would actually be night of Weds 21st and afternoon of Thursday 22nd (but in Australia morning of 22nd, and early hours of 23rd).

Basically - the table in the link above needs to have the exact spacetime coordinates specified (either by specifying that the date is for a particular timezone, or labelling the left column with "+1 day" or "1 day" as appropriate.

If you have a line to Amaldi organisers, could you ask?

Once that's known, we can add the link to the registration form to https://www.igrav.org/ and advertise to igrav-announce and our other networks.

Cheers,
Chris

Hi all

I’ve been liaising with the Amaldi Organisers on getting a link to our IGRAV meeting onto the Amaldi website, and on when best to schedule our meeting too.

At first Susan Scott (on behalf of the Amaldi LOC) was offering to *embed* our meeting within the Amaldi program, which was a generous offer but not that useful really since it would have made it harder – not easier – to avoid clashes.  So I iterated on that a bit, thanking Susan for offering to do this, but confirming that we really just wanted to make sure we avoided the Amaldi sessions (and especially the EPO ones) – i.e. our meeting was a “satellite” meeting of Amaldi (but unlike last time we were *also* trying to avoid scheduling it on a weekend),

So below is a new update from Erin O’Grady confirming the Amaldi schedule, but also that there may not a single EPO session for IGrav’s meeting to avoid!

I guess our best plan, then, is to seek to avoid the Amaldi sessions all together: I’ve forgotten when we were tentatively aiming to schedule the IGrav sessions, but am hoping we can do that….

As soon as we’re happy with the IGrav meeting registration page (sorry I’ve not followed the recent emails; maybe it’s all fine already?) we can let Amaldi know and they’ll include a link to us.

Cheers

Martin

Dear Martin

Susan Scott  has lopped us in regarding adding iGrav meeting details to the amldi14 website as a satellite event.

  *   If you already have an iGrav meeting webpage please send me the link and I am can add this to our amaldi14 website
  *   We are aiming to give speakers a talk time that is time zone friendly to where they are from,  so it may not be possible to schedule all EPO talks in one single session
  *   A possible solution would be if iGrav scheduled talks outside the 6 hours of time that that the Amaldi14 conference will be using (see table below), this would guarantee no overlap with any Amaldi EPO talks.
  *   Once we have finalised the Amaldi program of talks we could include the session times you allocate to iGrav talks in the program, and simply add a link to the iGrav website for further details about the talks.
