Re: Active Region Time Range On Solar Disk

[Nabil Freij]

Hello Marcos,

I am not personally aware of way to get that directly.

One idea I had in mind was to use the HEK (https://www.lmsal.com/hek/), you can query this via sunpy.net.Fido for an active region.

In theory the first and last entry in the database would give you the total time the active region was on disk.

Hopefully that works!

Hi,

I would like to know if there are codes in SunPy that can obtain the active region number on the given date of a day and the corresponding time range being on a solar disk?

Any suggestions are welcome.


Thanks,
Marcos

Hi Nabil,

Sorry for the late reply.

Thank you for your suggestion. I have found the solution, which is similar to what you recommended.

The query is Fido.search(a.Time(startT, endT), a.hek.AR, a.hek.FRM.Name=="NOAA SWPC Observer").

Cheers!

Marcos
