[IOError] RHESSISummaryLightCurve

[Fernando Hidalgo]

I was running without problems the recipe :

from sunpy import lightcurve as lc
rhessi = lc.RHESSISummaryLightCurve.create('2012/06/01', '2012/06/05')
rhessi.peek() 

or

from sunpy.time import TimeRange

from sunpy import lightcurve as lc
rhessi = lc.RHESSISummaryLightCurve.create(TimeRange('2012/06/01', '2012/06/05'))
rhessi.peek() 

The followings lightcurves of SunPy run well: GOESLightCurve, EVELightCurve and GBMSummaryLightCurve

but to create a lightcurve from RHESSI in the last months appeared the following error:

Hi,

I don't seem to be able to reproduce your error, however I don't have a windows box on which to test it.

It looks like the error is a result of NASA changing all its servers to HTTPS.

I can't test it, but you might find this patch fixed your problem: https://github.com/sunpy/sunpy/pull/2144

Stuart
