Search the Virtual Solar Observatory (VSO)#
To search the Virtual Solar Observatory (VSO) for SDO AIA data in all channels over a given time range, use the timerange (Time) and the instrument (Instrument) attrs,
>>> import astropy.units as u
>>> from sunpy.net import Fido
>>> from sunpy.net import attrs as a
>>> time_range = a.Time('2020/03/04 00:00:15', '2020/03/04 00:00:30')
>>> result = Fido.search(time_range, a.Instrument.aia)
>>> result
<sunpy.net.fido_factory.UnifiedResponse object at ...>

You can also search for specific physical observables using Physobs.
For example, you can search for line-of-sight (LOS) magnetic field measurements from HMI in the same time range,
>>> Fido.search(time_range, a.Instrument.hmi, a.Physobs.los_magnetic_field)
<sunpy.net.fido_factory.UnifiedResponse object at ...>

You can also use relational operators when constructing queries. For example, the AIA query above can also be expressed using the AND (&) operator,
>>> Fido.search(time_range & a.Instrument.aia)
<sunpy.net.fido_factory.UnifiedResponse object at ...>

Additionally, multiple operators can be chained together to, for example, search for only the 171 channel,
>>> Fido.search(time_range & a.Instrument.aia & a.Wavelength(171*u.angstrom))
<sunpy.net.fido_factory.UnifiedResponse object at ...>

The OR operator (|) can also be used to construct queries.
For example, to search for AIA data in this same time range from both the 94 and 171 channels,
>>> Fido.search(time_range,
... a.Instrument.aia,
... a.Wavelength(171*u.angstrom) | a.Wavelength(94*u.angstrom))

These relational operators are particularly useful when searching a given time interval for multiple instruments. For example, to find the HMI LOS magnetic field data and the AIA 94 and 171 data in the given time interval,
>>> aia_params = a.Instrument.aia & (a.Wavelength(171*u.angstrom) | a.Wavelength(94*u.angstrom))
>>> hmi_params = a.Instrument.hmi & a.Physobs.los_magnetic_field
>>> Fido.search(time_range, aia_params | hmi_params)
