Dates: We request support for calibration and scientific activities during the HRT high-resolution observations on 18 to 21 March 2022 : HRT will perform 20 minutes of high-resolution observations at one-minute cadence in each of the four days. Time window: The SO/PHI-HRT observations will take place on (year is 2022, time is UT) March 18th, from 10:10 to 10:30 March 19th, from 10:36 to 10:56 March 20th, from 11:27 to 11:47 March 21st, from 11:36 to 11:56 It is important to take into account that the specific times (UT) above may be subject to slight changes, and are still to be confirmed. Exact times will be fixed around two weeks (worst case) prior observation starts. Target(s) of interest: HRT will point at an AR, which will be identified, at the latest, three days in advance of the first observation on March 18th. The same AR is expected to be tracked during the 4 days of required co-observation. SO position on the relevant days is (Ecliptic longitude and latitude distance from Earth) March 18th, at 10:10, 31.558 degrees, 1.762 degrees March 19th, at 10:36, 35.936 degrees, 1.525 degrees March 20th, at 11:27, 40.672 degrees, 1.256 degrees March 21st, at 11:36, 45.537 degrees, 0.970 degrees
Additional remarks: We do not include here any request for other Hinode instruments in order to maximize the telemetry available for the requested SOT/SP maps. Pointing requires special coordination between SO/PHI and Hinode teams. The exact pointing coordinates (AR) will be provided about three days in advance of the requested Hinode/SP observation. |
