AMI-LA, e-MERLIN and MeerKAT radio detections of RS Oph in outburst

Following multi-wavelength reports of a new outburst of the recurrent nova RS Ophiuchi, http://ooruri.kusastro.kyoto-u.ac.jp/mailarchive/vsnet-alert/26131 (see also ATel #14834, #14838, #14840, #14844, #14845, #14846, #14848), we requested observations in the radio band with the Arcminute Microkelvin Imager Large Array (AMI-LA; Zwart et al. 2008; Hickish et al. 2018) at 15.5 GHz, e-MERLIN at 5 GHz and MeerKAT at 1.28 GHz. AMI-LA observations were requested as part of a long term transients monitoring programme (PI: Fender).
