High ionization lines such as<br />

NV could be produced by<br />

the GRB UV flux<br />

SIV is far from the explosion<br />

site in GRB050730<br />

Fox et al. 2008<br />

HIGH IONIZATION LINES<br />

(Prochaska et al. 2008)<br />

If this is the case, the NV<br />

should be close to the GRB<br />

(10pc)<br />

d (SIV) > 130 pc<br />

Multi-epoch spectra of a z>2 GRB is needed to search for NV variability<br />

Variation not observed in GRB080310 (De Cia et al. 2012)
