Apologies if this is obvious or something I should know, but I really can't find anything definitive... How can I programmatically access AAVSO light curves? I know I can manually request data from "https://www.aavso.org/data-download", but I have yet to find a way to grab this data automatically from something like Python. Does this functionality exist?

Accessing AID LC programmatically

Hi John

There is an API for light curve data, yes.

Here is an example of a request for del Cep V and Vis. data:

https://www.aavso.org/vsx/index.php?view=api.object&ident=000-BCQ-471&data=50000&fromjd=2459752.5&tojd=2460483.5&csv&band=Vis.,V&mtype=std

See also https://www.aavso.org/rest-api-specification-vsx

I need to find the documentation online again but I'm fairly sure it exists.
