TITLE: GCN CIRCULAR NUMBER: 10760 SUBJECT: GRB 100514A: Faulkes Telescope South observations DATE: 10/05/14 21:58:05 GMT FROM: Carole Mundell at ARI, JMU,Liverpool C.G. Mundell, R.J. Smith (Liverpool JMU), C. Guidorzi (U. Ferrara), A. Gomboc (U. Ljubljana) report on behalf of a large collaboration: "On 2010 May 14 at 18:57:31.55 UT the 2-m Faulkes Telescope South began observing Swift GRB 100514A (Markwardt et al., GCN Circ. 10759) at 3.55 min after the GRB trigger time. No optical afterglow is detected in R or i'-band filters to the following limits (relative to the USNO-B1) derived from co-added images: Mid time from Filter Limiting Magnitude trigger (min) ------------------------------------------------ 34.36 R > 20.3 38.55 i' > 19.5 ------------------------------------------------ We note that our limits seem to support a relatively high z for this burst, rather than a nearby extinguished afterglow, consistent with the lack of additional column density in the X-ray spectrum. Further followup observations are encouraged."
