26.3.20 AWR IH2 battery. Sun and light wind.

*

Thursday 26th Only a light easterly wind today. Very little cloud.

I replaced the 3V button cell battery in the AWR IH2 paddle yesterday. I was sick of having to enter the date, time and Home [Set park] Sync every single day. It even forgot the date and time after a lunchtime switch off! So I did a battery swap for a new one. 

This involved removing  the screws from the back of the IH2. Then gently separating the two halves of the yellow body moulding. There was a multi-pin plug and socket on one edge inside. Which needed to be separated perpendicularly. 

Then the internal screen needed to be removed to get at the battery underneath. Two more screws and another multi-pin and socket underneath. I didn't take any photos but it was all very neat in there. The date and time had zeroed, without battery power, so needed to be re-entered via the keypad. Job done.

10:00 50/45F. [In/out] Set up for imaging. The AWR date and time had held overnight after the new battery was fitted. Zooming the 800x600 view in

SharpCap showed large scale, thermal "shaking" of the sun's image. This is reflected in the quality of the resulting image from the first video capture.

There are a couple of subtle darker patches on the southern surface texture and I shall attempt to capture those. I am still getting what I assume to be magnetic "threads" on the sun's surface in these images. Though the seeing isn't remotely as good as it was later yesterday afternoon. 40% of 3k frames in AS!2, ImPPG and PhotoFiltre7.

I have opened the door on the ground floor door to improve air circulation. The image quality did not improve as it had later in the afternoon yesterday.
