Radio observations of Aql X-1

Observations with the Very Large Array (VLA) during the recent X-ray outburst of Aql X-1 (ATEL #450, ATEL #452, ATEL #464) give the following nominal flux densities at 4.86 GHz: 5apr05 (MJD 53465.55): 0.07 +/- 0.06 mJy/beam </LI> 12apr05 (MJD 53472.51): 0.27 +/- 0.06 mJy/beam </LI> 4may05 (MJD 53494.52): 0.03 +/- 0.05 mJy/beam </LI> The possible detection on 12apr05 would be somewhat surprising, given that the spectrum had softened significantly by that time (ATEL #464).
