Reports from the Projects

Argentina-NOVA

ArVO

• The 7th Byurakan International Summer School (7BISS) for Young Astronomers
• The Astronomical Surveys and Big Data 2 (ASBD-2)

AstroGrid

Australia-VO (ASVO)

The five nodes of the ASVO has been very active in the last few months. Here are some of the highlights:

• AAO Data Central

1. Developed and deployed a new SIAv2 service (written in python)
2. Implementing ObsCoreDM for the Anglo-Australian Telescope archive (data going back to 1974)
3. Developing automated data reduction pipeline, to be available to all hosted telescope archives
4. Developing an SSA service, integrated with telescope archive service, so that reduced spectra are available
5. Working on grant proposal to fund SimDM development effort

• SkyMapper

1. Data Release 2 of the Southern Sky Survey now world accessible through TAP and SIA
2. Data Release 4 to be release in around 2-3 months, with rebuilt SIA service backend

• Theoretical Astrophysical Observatory

1. Developing 3D visualisation system for simulated data (light cones etc)
2. New Genesis premade catalogues now available in the system: SHARK, Meraxes, SAGE & Dark SAGE

• MWA

1. Web portal rebuilt and released into production, including SSO service linked to Data Central
2. Evaluating Rucio, which is CERN's distributed data management system; unclear if VOSpace can sit on top of this system
3. Data in archive is coming up against 40PB allocation; need to do some cleaning up

• CASDA

1. Updated casda_vo_tools package on Github, including bug fixes and minor changes
2. Implemented astroquery.casda module, which includes region queries
3. Ingesting large amounts of ASKAP data, including POSSUM, WALLABY, GASKAP, and RACS
4. Last week CASDA ran a series of tutorials on using the system, including TAP, SIA and astroquery.casda

BRAVO

China-VO

• The new portal of National Astronomical Data Center both in Chinese and in English are online after re-design.
• Invited by AAS Journals, Chenzhou Cui introduced the PaperData service at AAS Publications Committee Meeting. Several VO projects contributed talks to the meeting.

ChiVO

CVO

Euro_VO

Euro VO activities continue in the ESCAPE project which is coming up for mid-term review in Q3 2020. This project is facilitating the development and implementation of VO technologies in the large astronomy infrastructures (labelled ESFRI in Europe). The training activities have been impacted by COVID-19 which has prevented the hands-on VO school being held. Options for a virtual event are being investigated. A list of activities can be found one the ESCAPE WP4 wiki pages (https://wiki.escape2020.de/index.php/WP4_-_CEVO).

Report from the TCG

• From last meeting
  • DM : Meas/Coords models and preparing for RFC2
    • Long discussion at TCG meeting on Jun 11; reinforced need for software implementation of DMs before REC approval; Shows reviewers that models are designed in support of a problem it is meant to solve
    • Request of the Exec is to make resources available who are able to prototype code exercising data models in applications utilities. These resources can work either directly with the data model teams, or via the applications working group.
• Fall Interop -
  • Sent Summer notice and Post-summer reminder to Interop email group - Save the date
    • One change for fall we plan to make is to allow >1 contributed talk in a session (~20 min category)

  • We suggest starting Monday night/Tuesday and running until Wed night/Thursday.

    That would be "night" west coast since dateline is in pacific. So late Mon to late Wed for west coast, morning T-Th for Europe, and late afternoon T-Th for Asia/Aus. That's mostly T-Th.

The meeting organization will be similar to our May Interop meeting. We will use Zoom as our shared remote service, and Etherpad for live notes and questions. We are planning to keep presentations to a single thread (no parallel sessions) and save a good amount of the time for your input and discussion. Sessions will be recorded and posted so that if you miss a session you can go back and view it. We will work to schedule sessions with reasonable times during the day for 2 of the 3 sessions a day in your time zone.

We envision asking the community for topics/presentations as we did last time and welcome your participation. We plan to make a slight adjustment to the Northern spring meeting and welcome the option of smaller presentations with >1 presenter in a session.

We are meeting now and will followup with more details in a few weeks.

We look forward to another engaging IVOA meeting in November.

Best Regards,
-Janet & Pat
(for the IVOA TCG)

Report from the Working Groups

EduIG

The first EduIG VM was held successfully on Aug 31. At the virtual meeting we want to exchange experiences we made with remote teaching during the COVID-19 pandemic around the globe. Roughly following the COVID-19 outbreak timeline, 7 speakers were invited from 5 different continents to share their experiences and feelings. Feedback for the VM are very positive. It was the result of close collaboration among IVOA EduIG, IAU DAEPO WG and IAU OAD office. Further collaboration projects were initiated at the workshop. The following discussion has started.
