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)
23-May-2019 - Connecting the corona to the solar wind

Spectroscopy club

This is for a group of people in Code 671 who are interested in solar spectroscopy. We have occasional meetings 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
