V1141 Aql outburst Dear Colleagues, The SU UMa-type dwarf nova V1141 Aql is undergoing an outburst. The present brightness seems to suggest a superoutburst. The last confirmed superoutburst was in 2002 July, which was studied by the VSNET Collaboration and by Olech (Acta Astron. 2003, 53, 85). The mean superhump period is reported to be 0.05930 d (relatively short Psh system resembling SW UMa). Systems with similar superhump periods tend to show an increase of the superhump period, which needs to be tested in V1141 Aql. The object is currently very favorably situated, and full coverage of the current likely superoutburst is strongly encouraged.
