abstract of observational proposal

Main Objective:
A HOP to support ALMA observations in cycle 4 for those proposers that do not have their own specific HOP request.

Scientific Justification:
The Atacama Large Millimeter/Submillimeter Array (ALMA) has recently accepted 15 proposals to observe the Sun in Band 3 and Band 6 during cycle 4 (observing from ~September 2016 ~ September 2017). These observations will provide high-resolution (~1-2", 2s cadence) observations of the solar chromosphere. The observations will cover an array of different science topics encompassing this region, where ALMA can serve as a sort of linear thermometer to probe these regions. Here we propose a set of generic observations for those studies, which do not make specific requests to Hinode.

request to XRT

XRT: Observations will vary based on target and telemetry and consist of:
- AR: Al-poly & thin-Be, better than 3 mins cadence, FoV: 128” x128”
- QR: Al-mesh & thin-Be, better than 3 mins cadence, FoV: 128” x128”
- Limb: Al-mesh & thin-Be, better than 3 mins cadence, FoV: 128” x128”
- Filters will be adjusted to accommodate current instrument and solar conditions

other participating instruments

IRIS:
Discussion with Bart De Pontieu, who recommends:
3620008063 | Medium dense 96-step raster 31.35x60 96s Deep x 8 | 912.38 | 661.89 | 0.5 | 9.5+/-0.1 | 912+/-0 | 38.0+/-0.0 | 38.0+/-0.0 | 38.0+/-0.0 | 38.0+/-0.0

ALMA
BBSO, NST
Tenerife as timing and weather allows

remarks

Dates: TBD - As many as 13 of these proposals may be observed from December 8-28 (weather and instrument dependent), with those remaining after the 28th to be observed from April 14 - 29, when the array is again in the correct configuration for those observations. 1 or 2 proposals will be observed from Jan 3 - Feb 1, and 1 or 2 proposals will be observed from March 1 - April 4. Details on the exact timings of the observations will be relayed as soon as possible.

Time Window:
Observations will take place during ALMA day:
13 ~ 20 UT in December 13:30 ~ 19:30 UT otherwise

Target(s) of interest: There are a variety of desired targets for this HOP, and it is understood that instruments may need to adjust their observing accordingly.
