# Searching the VSO¶

A simple example showing how to download data from the VSO with Fido.

Fido is the primary interface to search for and download data and will search the VSO if appropriate. First import it and the search attributes.

from __future__ import print_function, division

import astropy.units as u

from sunpy.net import Fido, attrs as a


We could ask for all SOHO/EIT data between January 1st and 2nd, 2001.

attrs_time = a.Time('2005/01/01 00:10', '2005/01/01 00:15')
result = Fido.search(attrs_time, a.Instrument('eit'))


Let’s inspect the result

print(result)


Now lets download this query. If we don’t provide a path it will download the file into the sunpy data directory.

downloaded_files = Fido.fetch(result)


You can check where the file was downloaded to.

print(downloaded_files)


More complicated queries can be constructed by using relational operators. For example, say we are interested in both eit and mdi data.

result = Fido.search(a.Time('2012/3/4', '2012/3/6'),
a.Instrument('aia'),
a.Wavelength(171*u.angstrom) | a.Wavelength(94*u.angstrom))
print(result)


Total running time of the script: ( 0 minutes 0.000 seconds)
