NASA/GSFC activities

This page contains documents and links for some activities that I've organized at NASA Goddard Space Flight Center (GSFC) since I arrived in 2015.

Data analysis

IDL plot objects

On 3-Mar-2016 I organized a session to discuss how to use the built-in IDL plot objects. The set of routines I used for the tutorial are available as a gzipped tar file.

Some links for further information are:

Making a mp4 movie from IDL

SDO image cut-outs

With Shea Hess Webber I gave a tutorial on 3-Dec-2015 to show how to obtain SDO cutout data from the Stanford JSOC service. Some information about this process is given below.

Guide to obtaining SDO cutouts at the Hinode/EIS wiki

Querying ADS from IDL

On 27-Jul-2017 I gave a demo of some new IDL software that I wrote for querying the ADS abstracts service. I have a short guide to this software.

Meetings and events

SunDC meetings

I co-founded the SunDC series of meetings in 2014 with Brian Dennis. These are 1-day meetings to bring together Solar Physicists in the Washington DC area on a focused science topic. The links below show the agendas for these meetings.

17-Jul-2014 - Solar flares
25-Feb-2015 - Solar eruptive events
14-Oct-2015 - Energy release in solar eruptive events
11-May-2016 - What IRIS is telling us about flare plasma
14-Jul-2017 - Small-scale heating in the solar atmosphere
17-May-2018 - ExoPlanet Space Weather (organized by Vourlidas, Kwon, Raouafi at JHU/APL)

Spectroscopy club

This is for a group of people in Code 671 who are interested in solar spectroscopy. We meet about a once a month with someone giving an informal presentation about their work. The list of past speakers and topics are given below:

On 2018 February 8 I organized a 1-day workshop at Goddard titled "Collaborative studies of the 10 September 2017 X-flare". There were 21 attendees and there were talks on the data obtained by EOVSA, RHESSI, Fermi, IRIS and Hinode/EIS - see the agenda. Some movies related to this event are available at
