abstract of observational proposal

Main Objective: Support the commissioning activities for SPICE and EUI with complementary Hinode observations, including co-alignment and relative intensity.

Scientific Justification: Solar Orbiter SPICE and EUI will undertake near Earth commissioning activities during spring 2020 when there will be good opportunities to observe simultaneously with Hinode, enabling a relative intensity calibration between EIS and EUI in Fe IX/X and He II 304 (FSI) and 256 (EIS). A full spectral atlas for taken at sun centre provides similar opportunities for SPICE, while EIS raster studies provide co-alignment opportunities with the SPICE dumbells.

To support SOU-60 and SOU-70:

atlas_120 OR atlas_60

atlas_120:
Duration: 2h 8m
Compression: DPCM
Data volume: 257 Mbit
Exposure time: 120s
Slit: 2"
Pointing: sun centre

atlas_60:
Duration: 1h 5m
Compression: DPCM
Data volume: 257 Mbit
Exposure time: 60s
Slit: 2"
Pointing: sun centre

EUI calibration: 13-19 May

HPW021VEL260x512v2
EXPOSURE TIME: 40s
RASTER: Scanning
SLIT: 2"
STEP SIZE: 3"
FOV: 260"x512"
RASTER DURATION: 1h3m45s
VOLUME: 122 Mbits
RATE: 37 kbits/s
COMPRESSION: JPEG85

Pointing: once at Sun centre, once each E/W limb

Prior to RSC-00 co-alignment: 30-31 May:

dhb_007 full disk scan,
RASTER DURATION: 1h9m
VOLUME: 72 Mbits
RATE: 17 kbits/s
COMPRESSION: JPEG90
Pointing:
For the full disk scan, the HOP 130 positions are rearranged to ensure a smoother overlap between
adjacent positions. David Brooks has software to calculate the pointings/timings. The full Sun scan takes
around 40 hours.

IRIS requests:
IRIS should follow all EIS pointings (that are not full-disk) with:

High datarate
3600259477 | Very large dense 320-step raster 105.3x175 320s Si IV Mg II h/k Dee | 3050.88 | 7383.29 | 1.65 | 9.5+/-0.2 | 3051+/-0 | 0.0+/-0.0 | 19.1+/-0.0 | 19.1+/-0.0 | 0.0+/-0.0

Low datarate alternative
3600109477 | Very large dense 320-step raster 105.3x175 320s Si IV Mg II h/k Dee | 2960.64 | 2476.28 | 0.57 | 9.3+/-0.1 | 2961+/-0 | 0.0+/-0.0 | 18.5+/-0.0 | 18.5+/-0.0 | 0.0+/-0.0

IRIS should also join the EIS full-disk scan.

Additional instrument coordination: Solar Orbiter SPICE and EUI.
