Chromospheric magnetic field observing campaigns

The observed targets are small magnetic features (mostly pores as of April 2010) on the solar disk.

Date Observing program InstrumentsLink to dataStatus
20 May 2008 impromptul IBIS, Hinode, TRACE online data Fully processed, comparison of IBIS and Hinode SP spectropolarimetry reported in Judge et al. (2010). Judge is working on two more papers: magnetic field diagnosis; photosphere-chromosphere-corona connections
4 May 2009 HOP 117 IBIS, Hinode, TRACE limited success, see the summary
2-9 Sep 2009 impromptu IBIS, Hinode, TRACE includes fast cadence (< 20s) IBIS data, partly reduced, see the observation log
27 Jan-6 Feb 2010 HOP 153 IBIS, FIRS, Hinode, TRACE Some joint FIRS/IBIS scans obtained. Slower cadence IBIS data with 18 minute FIRS rasters see the observation log
3-14 Jun 2010 HOP 153? IBIS+FIRS

IBIS+FIRS

3 June 2010. Good but variable seeing.

Some joint FIRS/IBIS scans obtained. 36s cadence IBIS data with 24 minute FIRS rasters of NOAA 11076 . See the observation log. One map of entire region (2 FIRS 4 slit rasters)
White light raw images of the two pointings.

IBIS+FIRS online data

4 June 2010. Good seeing.

More FIRS/IBIS scans obtained. 36s cadence IBIS data with 24 minute FIRS rasters of NOAA 11076 . See the observation log. FOUR maps of entire region (4 FIRS 4-slit rasters) for a total of about 4 hours of nice data (13:30-17:30 UT).

Full calibration set acquired for FIRS and IBIS (IBIS last table rotation had to be re-started).

5 June 2010. Excellent variable seeing.

NOAA 11076 . See the observation log. Data were acquired over 4 hours, 2 complete scans of NOAA 11076 (2x2 pointings), one of W43, N19 (2 pointings) started 16:18UT, of several pores, 1 more complete scan of NOAA 11076.

6 June 2010. Excellent variable seeing.

NOAA 11076 . See the observation log. Data were acquired over 3 hours, several scans of NOAA 11076. Clouds intervened during IBIS flats (only 20 acquired). Interesting limb data acquired at end of run.

IBIS+FIRS

8 June 2010. Clouds early, excellent variable seeing.

Targets: 1. limb N19 W 85 (with no AO), remnant of NOAO 11077; 2. AR near W42 S19, later named NOAA 11078. See the observation log. Interesting limb data acquired at beginning of the run.

IBIS+FIRS

9 June 2010. Cirrus early, excellent seeing.

Targets: W58 S21, NOAA 11078. See the observation log.
G band NOAA 11078, W58 S21 G band NOAA 11078, W53 S21
Small bipolar loop system at W32 S26 . See the observation log. G band, W32 S26
IBIS+FIRS

10 June 2010, some high level seeing.

Targets: NOAA 11078, 11079. Observations by DST observers (Judge traveling). See the DST observers observation log (pdf). Full polarization sequences obtained, but IBIS polcals had clouds.
IBIS+FIRS

11 June 2010. So-so seeing.

Targets: NOAA 11080. See the observation log. Full polarization sequences obtained.
IBIS+FIRS online data

12 June 2010.

Bad seeing early. Some cross-limb data were acquired early afternoon NOAA 11079 appear good, using off-pointing of AO. Probably the best off-limb data set of T864.
SDO AIA context
19-27 Nov 2010 T882 IBIS+FIRS + SDO

19 and 22 November, IBIS polcals only

23 November, IBIS+FIRS NOAA 11127 N24 W 15.3

Variable seeing, full set of cals (no polcal for IBIS). Both leader spot and followers mapped.

26 November, IBIS+FIRS NOAA 11128 S15 W E55

Variable seeing, full set of cals. IBIS scans made with Fe-Ca-H and Fe-Na-H, IBIS polcal done as well.
