Correct SRS areas for known overestimation

Hopefully you received my suggestions below to improve the explanation of the AR information (extracted from Solar Region Summary reports) you display on your Solar Monitor2 website. I’ve also noticed you do not display the AR longitude, which might also be useful to show?

You are probably aware that the SRS AR areas are quite inaccurate (up to 50% or more too small). This is related to the way the area’s are measured rather than the SOON observations themselves. More details can be found in this paper: https://doi.org/10.1093/mnras/staa2007. The only current publically available sunspot group area data that I know about is from the Kislovodsk solar station of the Pulkovo observatory. I can provide more details if of interest.

I believe we are displaying both the AR latitude and longitude but perhaps it is not as clear as it could be.
