 abstract of observational proposal
Main Objective:
To find the magnetic and chromospheric signatures of the onset of cycle 25.

Scientific Justification:
Small magnetic features and coronal bright points have been shown to indicate the bands of activity associated with the solar cycle. The precise location of these bands is important for predicting the timing of solar minimum and, more generally, the long-term variability of the Sun.

Recently, the onset of the activity bands of solar cycle 25 have been observed at high latitudes (McIntosh et al. 2014, McIntosh & Leamon 2017). These authors found a periodicity within the activity bands that is on the order of the solar rotation rate, but offset between the north and south.

To date, the signatures of solar cycle 25 have been measured by SDO/AIA and SDO/HMI. However, these instruments do not allow us to measure the spectral signatures of these features nor their vector magnetic field. Hinode SP measurements will give us high resolution vector field data, and IRIS will show the chromospheric spectral signature of the bright points.

 request to SOT
(Updated: September 2019)

---------- general instructions -----------

ID: 0x1ce (Normal 320"x82")

One full resolution, full width, half slit (512 px), normal map centered at longitude 0W and latitude 35N for the northern hemisphere. The spacecraft pointing in arcsec (after correcting for the SOT offset) can be computed with SSWIDL commands similar to the following:

offset=[22,39] ; SOT offset
print, ( 60.*hel2arcmin(35.,0.,date='2019/09/16 22:00:00') )-offset ; HOP 336 north

Additionally, one full resolution, full width, half slit (512 px), normal map centered at longitude 0W and latitude 40S for the southern hemisphere. The spacecraft pointing in arcsec (after correcting for the SOT offset) can be computed with SSWIDL commands similar to the following:

offset=[22,39] ; SOT offset
print, ( 60.*hel2arcmin(-40.,0.,date='2019/09/16 22:00:00') )-offset ; HOP 336 south

Although tracking curves are preferred for these observations, if there are not enough available, then either or both maps may be run with fixed pointing.

---------- additional instructions (for eclipse season) -----------

ID: 0x12c (Fast Map, Full FOV)

During eclipse season, please run a full width, full height fast map at the same pointings, instead of the normal maps. Each of these should run twice, in 2 consecutive orbits, for redundancy. Full height is requested because SOT offsets in Y are large and slightly uncertain during eclipse season.

---------- historical pointing list-----------

longitudes: centered on central meridian for both scans
latitudes:
centered on 37.5N and 37.5S (until Sept. 2019)
centered on 35N and 40S (Sept. 2019 to present)

 request to XRT

IRIS Requests:
Each observation requires 4 pointings for each raster. Northern hemisphere pointings: [-150, 640], [-50,640], [50, 640], [150,640]. Southern hemisphere pointings: [-150, -695], [-50, -695], [50, -695], [150, -695].

Timing should follow the Hinode pointing as closely as possible, but at the least we request all rasters span no more than 12 hours. Avoid SAAs if possible.

High data rate:
3620258076 | Large dense 320-step raster 105.3x120 320s Deep x 8 FUV spectrally | 2993.20 | 3785.93 | 0.9 | 9.4+/-0.1 | 2993+/-0 | 37.4+/-0.0 | 37.4+/-0.0 | 37.4+/-0.0 | 37.4+/-0.0

Low data rate:
3620108076 | Large dense 320-step raster 105.3x120 320s Deep x 8 Spatial x 2, Spe | 2932.08 | 1268.12 | 0.3 | 9.2+/-0.1 | 2932+/-0 | 36.7+/-0.0 | 36.7+/-0.0 | 36.7+/-0.0 | 36.7+/-

 remarks
Requirements and desires: weekly observations of a high latitude band in the northern hemisphere are required. A similar set of observations in the Southern hemisphere is desired.

Time window: coordination with IRIS is desired, within the same 24 hour interval is required. Short interruptions (eclipse season or other) are allowed.

Target(s) of interest: High latitude bands (600h wide, centered around the central meridian) of quiet Sun, one in the Northern and one in the Southern hemisphere. IRIS should use the same latitudes as Hinode.

Additional Remarks:
This IHOP is concerned with detecting the bright point signals of solar cycle 25. These bright points have been shown to be periodic with a period close to the rotation rate, and confined to narrow latitude bands. Therefore, we request the observations be performed ~weekly at specific locations in the northern and southern hemispheres, on precise dates selected by the proposer. The periodicity and locations of the BPs differs between the northern and southern hemispheres. Our primary science goal is to measure the northern hemisphere. If time/telemetry allows, we wish to measure the southern hemisphere separately.
