Field-of-View plots tool in the HelioPhysics Archive

This tool provides a way to visualize the Field-of-View (FoV) of the Solar Orbiter EUI/HRI, PHI/HRT, and SPICE instruments,
as seen from Solar Orbiter and from an Earth perspective (when possible). These projections are performed using SunPy.
The full Sun images from a Solar Orbiter perspective are provided by the EUI/FSI instrument (174 Å wavelength) and from
Earth by NASA SDO AIA instrument (171 Å wavelength). This tool also displays the position of Solar Orbiter, Parker Solar
Probe, Bepi Colombo, Stereo-A with respect to Earth and the Sun at any time. Below the top plot, an inventory of the main
datasets produced by these high-resolution sensors with a limited FoV of the Sun is provided.

FoV and inventory plot descriptions

The plots show the FOV(s) for one or several selected sensors. These FOVs are plotted over the EUI/FSI-174 image that is recorded closest in time. The maximum time difference between the FSI image and the shown high-resolution observation is 7.5 minutes. As far as observations are available, the tool contains plots for EUI/HRI, PHI/HRT, and SPICE. In addition to the Solar Orbiter view, the tool also shows the perspective from Earth with the projections of the selected sensor FOVs onto the SDO/AIA-171 image closest in time. The table contains the helioprojective FOV coordinates from both perspectives and the time duration of the shown observations. For the given observation time, the radial and longitudinal coordinates of Earth and Solar Orbiter (as well as Bepi Colombo, Parker Solar Probe and STEREO-A) are depicted in the accompanying overview plot on the left.   

For data overview, the tool contains inventory plots that show the availabilty of observations of EUI/HRI, PHI/HRT, and SPICE for the selected time period. If less than a Carrington Rotation (CR) is selected as time period, the inventory plot contains the whole respective CR. If more than a CR but less than a year is selected, the inventory plot extends to the whole respective year. If more than a year is selected as time period, the inventory plot shows the whole mission duration.

Browsing the plots

The plots can be accessed just by selecting a certain period in the calendar panel on the upper left of the webpage and by using the forward and backward buttons at the center of the page to navigate within this period (see image below, courtesy of H. Middleton, ESA).

• The first available day is 19/11/2020 where first systematic remote-sensing observations were taken.
• The last day is currently 19/01/2025. 

Zooming a FoV plot

For zoom and detailed inspection of the plots, it is recommended to "right-click" on a plot and
to select the option "Magnify Image" (for Microsoft Edge only) in the drop-down menu.

Data download

The field-of-view tool allows direct access to the underlying plot data such as FOV coordinates, spacecraft position, observation times etc. in csv format. Furthermore, direct access to the Solar Orbiter Archive (SOAR) data for the selected instruments and time period is possible.
