==== CSS Early Career Presentations ====

The Neutrino Frontier is planning to use some of our parallel time at the Seattle Community Summer Study meeting  on talk presentations from **early career participants**.
 
We are hoping for as many of these as possible to be in person, although we will accommodate remote talks.  **You must be registered for the meeting in order to present.**  The time allotted per presentation will depend on the total number of presentations and amount of time available.
 
Please submit abstracts by June 1, here:
 
https://docs.google.com/forms/d/e/1FAIpQLSeGD-4h84Z07RAlKN7_q4nHOFmBagaa0ThW7veN_2PwvA_E_Q/viewform?usp=sf_link
 
If you need confirmation of a talk slot by a particular date, or if you have constraints, please let us know in the comments (although please be aware that we may not be able to provide information about specifics of talk length and scheduling until later in June.)
 
It is okay if your talk presentation content overlaps with poster presentation content.  Any NF-related topic is eligible, including topics overlapping with other frontiers.

=== Past Information ===

===== White Paper Coordination Meetings =====
As we wake up from the pause, we are organizing 1.5-hour "white paper coordination meetings" featuring NF-related white-papers-in-progress.  Each meeting has nominally two 45-minute slots (although there is flexibility for use of them.)   The idea will be to coordinate submissions and get people working together effectively.  You are encouraged to contact the Topical Group conveners if you would like to lead or participate in one of these coordination meetings- for example, you might want to recruit collaborators, or to explore a joint white paper with another group or between Frontiers.   We fully expect some of these to lead to dedicated further meetings on a particular topic.

We have allocated time slots about every two weeks, but we can add more or find different times if there is demand.

**The Zooms for these are sent by email to the NF mailing list and posted in the #neutrino channel in Slack, several days ahead.**

==== Waking Up From the Pause ====

We are planning to resume Neutrino Frontier Snowmass activities towards the end of the month of June 2021.

* The Topical Group conveners will resume regular meetings, starting June 24.

* The dates for the Neutrino Frontier meeting are set:** March 16-18, 2022**.  The meeting will be hosted by ORNL.  We are hoping that it will be in-person, although formal approval of this is not yet possible, so initial plans are for a virtual meeting.

* The pan-Snowmass white paper deadline is March 15, 2022.  We have a [[https://docs.google.com/forms/d/e/1FAIpQLSex-Y5rHdGugIgDuPZEs5Uy3Yv7W8Dqhy_hiiHm0cEMGj3NWw/viewform?usp=sf_link | Google forms link]] where you can submit information about planned NF-related white papers and 
[[https://docs.google.com/spreadsheets/d/1ORQe5LYSaLQ7rsg7UihlD485cUDAxWlb9qZsOlgutIs/edit#gid=0 | a spreadsheet]]
updated around once a week, where you can see what is being planned by community members  (so you can get in touch with them if you wish).

* Starting later in the summer, we will be planning regular NF-community-wide (virtual) meetings featuring planned white papers, based on the submissions via this form.  The idea will be to coordinate submissions and get people working together appropriately. Topical Group conveners will suggest these.  We are happy to get your input about topics to cover.

* Please expect to  hear more from us around the end of June.

==== Snowmass Pause ====
After taking into account input from the Topical Group conveners and the community, we plan to have approximately a **six-month pause** in Snowmass activity for the Neutrino Frontier, with activities restarting up **no earlier than June 2021**.
 
  - The NF meeting planned for mid-March will be rescheduled for 2022 (assuming in person, it will be at ORNL).
  - Some already-scheduled activities will still take place, but no new Snowmass NF workshops and meetings will be scheduled during the pause.  Please see the calendar below for more information.
  - Conversations and collaborative activities can of course still take place on Slack and elsewhere during the pause, as community members wish.
  - [[https://snowmass21.org/submissions/start|Snowmass contributions]] are driven by the community, and of course, work on these can still take place as desired.  
  - We’ll send occasional update pings to the community during the pause, and we will communicate the detailed plan for work following the pause as it is developed.

===== Submitted LOIs (2020)  =====
Letters of Intent submitted to Neutrino Frontier are [[https://www.snowmass21.org/docs/files/?dir=summaries/NF| shown in this link]]. Here is the list of submitted LOIs that include NF as primary or secondary topic. 
 First index before "/"  corresponds to the primary frontier used for the submission.
Please go to the “topical” group to see the LOIs submitted to specific topics. 
<hidden click here to view LoIs submitted to this frontier>
{{url>https://www.snowmass21.org/docs/files/list.php?frontier=NF  border 100%,9500px}}
</hidden>

We have assigned each NF-relevant LOI to one or more NF topical groups, so that the topical group conveners are aware of the content .  [[  https://docs.google.com/spreadsheets/d/1OdolyQU38GrDzUZartKfz0u7f9DiILzQkGecO-HBaMQ/edit?usp=sharing|A spreadsheet with LOI information can be found here ]].

===== Past Information on LOI submission (2020) =====

The topical group conveners need timely input in order to plan activities effectively. **<color #ed1c24>The August 31, 2020 deadline is a hard deadline for NF LOIs.</color>   We will guarantee consideration of LOIs submitted by this date in planning of activities and writeups.**  After this deadline, conveners may still consider LOIs, but there is no guarantee.

You are encouraged to use these templates to [[https://snowmass21.org/loi| submit a Snowmass LOI]].  These are not required, but indicate the information we would like to have.  The checkboxes are especially encouraged in order to route LOIs effectively to the right topical groups.     Text is limited to two pages.  We interpret this limit as referring to the body of the text, and not including title, author list, references, abstract or other preamble material.   We ask you to limit abstracts to 200 words.
