(a) Plot EUVI data + GOES light curve

To start data analysis with EUVI data we like to see a catalog of EUVI data in a graphic display over some time interval, if possible along with a GOES light curve, which shows us the activity level of the Sun in soft X-rays, from which we can gather the times of flares and CMEs.

Let us check if EUVI observed on Dec 13, 2006 and whether there was a GOES flare.
The commands for this example in IDL are:

IDL>
date ='20070509' ;'YYYYMMDD' date of observation
tstart ='000000' ;'HHMMSS' start time interval for image selection
tend ='240000' ;'HHMMSS' end time interval for image selection
type ='img' ;'img','cal', 'seq'
instr ='euvi' ;instrument
dir ='~/work/' ;local working directory
euvi_goes,date,tstart,tend,type,instr,dir

The plot shows two small flares of about C1 GOES class around 2:00 UT and 14:00 UT. EUVI was observing all day, with a small data gap around 15-16 UT in spacecraft A[head] (middle panel), while spacecraft B[ehind] was observing continuously (lower panel). Every vertical mark in the lower two EUVI displays indicates the time of an image taken, with the wavelengths indicated on the right hand side.
The program EUVI_GOES.PRO produced also a postscript file of the graph and you should find in your current work directory with the filename="goes070509.ps".
