Addition of ARs and solar flares further back in time into this database

[faster328]

There was an addition like this on geomagnetic storms into the database. Can we have a poll on whether we add more sunspot regions/active regions and solar flares into the database?

(Note: This is not an official poll, it is a suggestion by faster328)

Poll votes are private.

I would vote Since 1976 (All SESC/NOAA ARs) and Since 1976 (When regular X-ray flux became available), respectively for ARs and solar flares, due to the time range being the same.

 

--AR 5395--

This is old AR 5395 when it reached its peak size of 3600 MSH on March 17, 1989 (note that AR 5395 is the big region on the northwestern limb/top right), that is famous for the March 1989 geomagnetic storm: https://solarwww.mtk.nao.ac.jp/mitaka_solar/wl-fulldisk-photo/calendar/1989/jpg/wl19890317_001.jpg

Please discuss anything about old AR 5395 and the March 1989 geomagnetic storm here.

Right now flares are out of the question as those have yet to be processed into science quality data. Current science quality X-ray data only goes back to 1995 and hopefully the rest will be completed later this year.

For sunspots, it looks like the recorded number of spots, size, classification, and location on the solar disk would be needed, probably along with imagery that is rotated so the Sun's equator is in the horizonal position.

When will the X-ray flux from solar flares before 1995 processed into science quality data?

For the sunspot data, give me the entire summary for AR 5395 and AR 6659, excluding solar flares and sunspot images.

 

There are science quality data since GOES-8 was available. Data from GOES-1 to GOES-7 are not science quality data currently.

That’s why our archive starts in 1996.

if previous years would become available we can always try to extend it like we’ve done with geomagnetic storms (Kp, Dst).

but beside the science data (without correction factors), we would still need to process it to extract solar flares to put into the database. SWPC doesn’t always include each C-flare for example in their lists so that’s also an issue, I don’t think SWPC has a flare list of the old data prior to 1996. I do know that we had to do a lot of modifications to the solar flare data from SWPC so even if that data exists, it won’t be fun 🙈.

There is some history about the poll.

Publicizing which users are participating in a vote has to be some of the worst polling practices ever.

I see now that that seems to be inherent to the polling software used for the forum though, but I guess I still wouldn't highlight it like that.

GOES 8 through and a few others were released in late 2023. As I said, the remaining science quality data is expected to be released later this year for the remaining satellites. The completion of all of the satellites has been pushed back at least a year already though, so it won't be surprising if the completion date is pushed back again into 2025.

I don't have that information. I was more expecting that you might already might know where that information can be found. If there is no data, how can it be added to the archive?
