In April, the AZ was 205° a discrepancy of 9.8° or 10.8° with the -1° bias, and the inclination was 16.8.

N02A
In April, we found an azimuth of 323° and expected 320.4°, a discrepancy of 2.6° or 1.6° with the -1° bias. The inclination was 15.9°. One post is leaning over a bit. It will be interesting to see how this CR reacts to the thaw. I imagine all the tie-downs will be loose. Ron and I talked on the phone about replacing this CR with an ASF Ring-based Reflector after things thaw out and dry up.

N03A
In April we found the AZ to be 332° a discrepancy of 2° or 1° with the -1° bias. The inclination was 18°. The tiedown holding the ring base was taught.

N31A
In April, we found the CR to still be in great shape with an AZ of 331°, a discrepancy of 1° or spot on with the -1° bias. The inclination was 17°.

On Wednesday, April 10, 2024, we visited the NISAR corner reflectors in Delta Junction, and on April 19, 2024, we visited Quist farm. We took pictures, checked/readjusted the tie-downs, measured the pointing angles and inclinations, and for the first time, we didn’t have to remove snow from the reflectors! I have attached an Excel spreadsheet showing the expected azimuth and inclinations for each corner reflector, along with the actual measurements we took. Your work comparing our Bruton Compasses reveals a -1° bias. That bias is reflected in a separate column in the spreadsheet. There is a tab at the bottom for each monthly inspection. I have also attached pictures from each location and have a few more upon request. The declination on our compass was set at 16°.
