ESA Archival Research Visitor Programme
15:30-16:00     Wrap-up discussion on Solar MACH (All)

Solar MACH 
Solar MACH is for the moment a single Jupyter Notebook available at
It allows to visually magnetically connect a number of ESA and NASA spacecraft in the inner heliosphere to the Sun.
Particularly useful for Solar Energetic Particles (SEP) wide spread events on multiple spacecraft to better understand SEP transport

This Jupyter notebook provides a rough overview, a kind of quicklook tool for SEP widespread event to check from which spacecraft data shall be further analysed. Solar wind speed is fixed at 400 km/h by default and can be manually changed.

  • Improve accuracy
    + Implement a live access to solar wind measurements from L1 monitors (SOHO, ACE, WIND or DSCOVR) but also STEREO, Solo (from Heliopy)
    + Connectivity with the Parker spiral is not really the magnetic connectivity: inclusion of PFSS modelling, connection to CCMC tools?
    + PFSS modelling: one group in San Diego to contact, and MADWAG and IRAP team in Toulouse, PFSS is good for Earth not for backside observers

  • Inclusion of more spacecraft
    + Helios but spice kernel missing to be interacted with people at JPL or in Toulouse
    + WIND (no spice kernel but CDPP in Toulouse generated one and could be requested)

  • Other scientific interests
    + Preparation of Solar Orbiter out of the ecliptic measurements
    + Re-visit older events with Ulysses
    + Stereoscopic helioseismology

  • Jupyter notebook new functionalities (wish list)

+ Using the archives to display videos of the Sun (SOHO EIT, SDO AIA, Proba-2 SWAP+EUI eventually) + HMI/MDI (PHI eventually) + Lasco during the time period requested
+ Using the archive to display of selected measurements from the spacecraft chosen (at Mars, cosmic ray detector)
+ Latitudinal view
+ Zoom in 
+ Separation angle for Stereoscopic helioseismology (already implemented for a single time)

  • Eventually
    Inclusion of this work in SunPy or HelioPy for instance

This Jupyter notebook will be advertised to the Solar Orbiter MADAWG community through Alexi Rouillard, SEP groups in the US to involve early career scientists to participate and maybe develop similar Jupyter Notebooks based on this one and/or further develop its functionalities

New SOHO archive at ESAC (in development, not public)
Wish list of new functionalities

+ Time series visualisation

  • Quicklook plots and on-demand generation of Energetic particles intensities and CELIAS proton monitor solar wind speeds, density, temp.
    Wish to combine different instruments? further discussions needed with the proposer (N. Dresing)
  • Share times series through the HAPI (Heliophysics API) interface

                Requires to develop a Parser that could be used for SOHO and the other archives 
                +metadata curation of SOHO data to fit standard HAPI header
                Hands-on workshop proposed by B. Cecconi

Data delivery

  • Data shall be delivered within a time period at certain cadence such as very 12h or every 24h, to be further discussed with the proposer (A. Veronig) 

CDS data visualisation

  • CDS: Quicklook plot visualisation of intensity image with one emission line
    These intensity maps are calculated from the spectra and are available on the RAL website
    L. Harra to contact RAL if those could be transferred to ESAC

+ Increase SOHO data distribution and visibility

  • SOHO SSA availability through VESPA with the implementation of EPN-TAP,  further discussions needed with the proposer (B. Cecconi)
  • SOHO SSA availability through Solarnet, Solar Virtual Observatory (SVO), link to this virtual observatory, further discussions needed with the proposer (M. Roth)

+ Movie generation of EIT, LASCO and MDI

  • Alternative solution to Youtube: science media platform
  • Bernhard Fleck: Video generation is not a priority and can/shall be done through JHelioviewer

  • No labels
