Sun May 2025 Sphere Synoptic - Inti Partner and Naming _YYYY-MM-DDTHH-MM-SS

I installed the new verion 1.2 of Inti Partner which has a tab Synoptic. It's possible to create a mp4 or GIF file made from solex images over multiple days. The end result is a simulation of the sun's rotation. I had some issues with the error "Date Error" but this is now fixed:

1) only use PNG/fits/ files

2) make sure the Log file is available at the same or upper map

or 

1) if you don't have the Log file, change the naming of the file to following format:

_YYYY-MM-DDTHH-MM-SS_  

2) be aware to change timing to UT time

I used files from May 2025: May 30, 19, 14, 11 and May 2nd. The synoptic maps identified 21 active regions from AR 4070 till AR4103

AR 4070 lat=-12.0° lonCarr=10.0°
AR 4072 lat=-19.0° lonCarr=325.0°
AR 4076 lat=5.0° lonCarr=305.0°
AR 4079 lat=8.0° lonCarr=244.0°
AR 4081 lat=7.0° lonCarr=213.0°
AR 4082 lat=-9.0° lonCarr=188.0°
AR 4084 lat=-21.0° lonCarr=129.0°
AR 4085 lat=3.0° lonCarr=139.0°
AR 4086 lat=7.0° lonCarr=207.0°
AR 4087 lat=15.0° lonCarr=57.0°
AR 4089 lat=17.0° lonCarr=28.0°
AR 4090 lat=-13.0° lonCarr=20.0°
AR 4091 lat=-13.0° lonCarr=33.0°
AR 4092 lat=-13.0° lonCarr=337.0°
AR 4094 lat=20.0° lonCarr=332.0°
AR 4096 lat=6.0° lonCarr=306.0°
AR 4099 lat=-13.0° lonCarr=255.0°
AR 4100 lat=8.0° lonCarr=243.0°
AR 4101 lat=3.0° lonCarr=259.0°
AR 4102 lat=-22.0° lonCarr=297.0°
AR 4103 lat=-17.0° lonCarr=287.0°

Sun January 4th

A 5cm layer of snow and a perfect blue sky. Sol'Ex time :)
My SSM3 Seeing monitor registrated very good seeing with levels below 1 arcs with sometimes below 0,5arcs. I still have issues with my allignment of the spectral lines which are curved. Maybe I need to adjust the slit?

ROS 2026 - Registration is open

The next Solar Observers’ Meeting (ROS) is scheduled for June 13–14, 2026, in Serbannes. Once again, the program will feature many instruments dedicated to solar observation in white light, calcium lines, and the H-alpha line for observing prominences, as well as the latest filter innovations. The Sol’Ex spectrograph will also be part of the event.

Registration is now open.

My first observation of the Sun this year.
Moderate conditions and settings of Sol'Ex not perfect, mainly the north side of the Sun.
