1 I have been studying EVE H. S. Hudson Space Sciences Laboratory, University of California, Berkeley, USA Astronomy & Astrophysics Group, Glasgow Glasgow Jan. 19, 2011

2 Flare SOL2010-06-12T00:57 Glasgow Jan. 19, 2011

3 More motivation Glasgow Jan. 19, 2011 Milligan & Dennis 2009

4 Sun-as-a-star EUV tools SOHO/SEM: broad EUV band at 30.4+-4 nm SDO/EVE MEGS-A: far-UV, 1 A resolution, 10 s cadence (data available) SDO/EVE MEGS-B: near-UV, 1 A resolution, 10 s cadence (to be released in a couple of weeks) Glasgow Jan. 19, 2011

5 EVE 304A for SOL2010-06-12T00:57 Glasgow Jan. 19, 2011

6 Line detail, total and subtracted Glasgow Jan. 19, 2011

7 304 time series, one day Glasgow Jan. 19, 2011

8 Flux and Doppler, one day Glasgow Jan. 19, 2011

9 Doppler shift? Glasgow Jan. 19, 2011

10 EVE 304 narrow vs SEM Glasgow Jan. 19, 2011

11 EVE 304 vs SEM, broad Glasgow Jan. 19, 2011

12 EVE 304, SEM, EVE broad Glasgow Jan. 19, 2011

13 Broad passband Glasgow Jan. 19, 2011

14 Comments on EVE Lots of lines to work with He II spectrum in the impulsive phase (can see Ly-  and a hint of Ly-  in SOL2010-06-12 Need bigger flares Looking forward to near UV (out to 1500A, I think) as a part of WLF characterization Glasgow Jan. 19, 2011
