Search for multiple wavelengths with Fido#
Use the Wavelength to search for a particular wavelength:
>>> from astropy import units as u
>>> from sunpy.net import Fido
>>> from sunpy.net import attrs as a
>>> time_range = a.Time("2022-02-20 00:00:00", "2022-02-20 00:00:30")
>>> aia_search = Fido.search(time_range,
... a.Instrument.aia,
... a.Wavelength(171*u.angstrom))
>>> aia_search
<sunpy.net.fido_factory.UnifiedResponse object at ...>

The “|” operator can be used to combine multiple wavelengths:
>>> aia_search = Fido.search(time_range,
... a.Instrument.aia,
... a.Wavelength(171*u.angstrom) | a.Wavelength(193*u.angstrom))
>>> aia_search
<sunpy.net.fido_factory.UnifiedResponse object at ...>

When searching for more than two wavelengths, it is more practical to use the sunpy.net.attrs.AttrOr() function:
>>> wavelengths = [94, 131, 171, 193, 211]*u.angstrom
>>> aia_search = Fido.search(time_range,
... a.Instrument.aia,
... a.AttrOr([a.Wavelength(wav) for wav in wavelengths]))
>>> aia_search
<sunpy.net.fido_factory.UnifiedResponse object at ...>
