Active Region Guide

 

Please take care with the AR programs that you use for planning. Remember that we want the active region structure to be mostly unsaturated, so if during your DV work, you notice that all images in a particular filter are saturated over the majority of the active region, then it is time to switch programs! 

XOBs should include G-band light-leak image (VLS close,1x1 binned) and G-band image (1x1 binned) at least every hour. Here is a helpful guide for some of the most common "families" of 2-filter active region programs:

 

 

AR (Filter-Ratio with Al/Poly and thin-Be) with PFB, 512x512 at 1064, 1048, thick-Al context with G-band (1ms/1ms leak) XXX cad

These are the programs that resulted in saturation being consistently seen in the Al/Poly images in late 2019. This program utilizes only the AEC 2. This is fine for fainter ARs but results in consistent saturation in the Al/Poly for moderate to bright ARs. These programs should only be used if the AR is known to be faint or if previous observations resulted in under-exposed images.

Members: #1C6C (240s cad), #1C74 (150s cad), #1BDB (120s cad), #1BC4 (90s cad), #1B9D (72s cad), #1C60 (60s cad), #1BCB (30s cad), #1BED (20s cad)

 



AR (Filter-Ratio with Al/Poly and thin-Be long/short pairs) with PFB, 512x512 at 1064 1048, thick-Al context with G-band (1ms/1ms leak) XXX cad


These programs take images in long (AEC 2) and short (AEC 3) pairs. The loop structure is set up so that the majority of the images are taken in long/short pairs, so these programs should be used when getting the long/short pairs is the primary goal.


Members: #1C94 (300s cad), #1C93 (240s cad), #1C91 (180s cad), #1C20 (120s cad), #1C2B (90s cad), #1CA6 (72s cad)

 



AR - Standard Core - (Filter-Ratio with Al/Poly and thin-Be long/short pairs) with PFB at 1064, 1048 thin-be, and Al/Poly context with G-band (1ms/1ms VLS=CLS), XXX cad

These programs take a single long (AEC 2) and short (AEC 3) pair and will then mainly loop over images with AEC 1 set. AEC 1 should not have the same issues with saturation seen with AEC 2, but has a slightly less strict upper threshold than AEC 3. These programs should be used on moderate to bright ARs when a small set of long/short pairs is desired but the long/short pairs are not the main goal of the
observations.

Members: #1BFE (300s cad), #1CD7 (180s), #1BBA (120s cad), #1BB9 (90s cad), #1BDE (72s cad), #1B89 (60s cad), #1BA9 (30s cad)



AR Standard-A (Filter-Ratio with Al/Poly and thin-Be) with PFB, 384x384 at 1064 1048, thin-Be, thick-Al, Al/Poly context with G-band (1ms/1ms leak) XXX cad

These programs only use AEC 3 and loop over the filter set with just AEC 3. This should be used when the AR is known to be moderate to bright.

 

Note: 1BA4 is different in that it loops mainly with AEC 1 but the others loop with AEC 3. 1BA4 can still be used but be aware the upper threshold on AEC 1 is less strict than the AEC 3 threshold.


Members: #1C50 (240s cad), #1BB8 (120s cad), #1BA3 (90s cad), #1C8B (60s), #1BA4 (30s cad)

 

 

AR Standard-B(Morphology) with PFB, thin-Be 384x384 at 1064 1048, XXs-cad, G-band (1ms/1ms VLS=CLS)

 

These programs only use Thin-Be. Typically run at a higher cadence if Thin-Be is a specific science goal. Uses AEC3 and has a PFB.

 

Members: #1C22 (120s cad), #1C25 (60s) #1CB5 (30s)

 

 

AR - Filter-Ratio with thin-Be (long/short pairs) and Med-Be (short) with PFB, 384x384 at 1064 1048, with G-band (1ms/1ms VLS=CLS), XX cad

 

These programs take short and long Thin-Be images (AEC2 and AEC3) and then a Med-Be image with AEC 3. This should be used if the goal of the science is to capture images with Thin-Be and Med-Be instead of the typical Thin-Be and Al-Poly.

 

Members: #1CE7 (180s cad), #1CA7 (120s cad), #1C97 (60s cad)

 

 

AR-(filter ratio Al/poly thin-Be), 256x256 at 1064 1048, with G-band 1ms, PFB, 30s cad

 

These programs take Al/Poly and Thin-Be images with AEC 1 at 256x256.

 

Members: #1CB8 (30s cad), #1CB9 (60s cad)

 

 

 

AR-High cadence (10s thin-Be only) XXX x XXX at 1064 1048

 

These programs only Thin-Be images with AEC 3 at a very high cadence (10 seconds)

 

Members: #1CD5 (512x512), #1CD6 (384x384), #1CC2 (384x384 8s), #1CC3 (256x256)

 

 

Regular Synoptics


Please ensure that Al-mesh is included in the synoptic program for continuity of full-sun observations throughout the Hinode mission. Planners can update the exposures, as needed, for the Synoptics. This may mean writing a new XOB instead of using an already existing XOB, though at this point in the mission the majority of combinations have been created.

 

As the Sun gets more and more active, we may need to modify some of the very short exposure time sets to utilize the correct G-band 1ms. Please be wary when using any of the synoptics not currently on this list as this covers everything used going back to 2017. Others not on this list will likely have a 3ms G-band or longer.

Regular 7-Filter Synoptics

 

7-filter synoptics XOB should be run at least twice a week. In order to keep the 7-filter synoptic program under 7 minutes, we take thick filter images only once in these programs (it was twice before). In compensation, we decided to run a 7-filter synoptic twice a week. Additional 7-filter synoptics can be taken whenever telemetry is available or if there is a specific science request for it (such as HOP 130).

 

All the XOBs below use a 1ms G-band exposure time. Synoptics not on this list should be examined carefully since they are likely to use an incorrect G-band exposure time.

CME Watch


Please make sure the CME watch program contains G-band images that are 512x512, bin 1x1, 1ms exposures (VLS open/closed) taken roughly once per hour. No 2x2 binning, or exposures longer than 1ms.

When no active regions are on the disk, the short exposure (AEC3) is too short. It would be better to switch to taking long/medium pairs (AEC2/AEC1) for better results. However, if ARs are on the disk then the long/short pairs (AEC2/AEC3) are better.

If Hinode is going to follow Quiet Sun/Coronal Holes, with no HOP request to XRT, then run CME watch with long/medium/short exposure pairs if there are active regions.

 

Running CME watch programs through SAAs produces mixed results. For the higher cadence observations (~180s) the short exposure time decreased to near 0. However, for the lower cadence observations (~360s) the short and long exposure times tended to max out (16s for long and short pairs). Generally, the programs recovered after a few exposures, but it did create a few bad images.
