Cbet nr. 3783, issued on 2014, January 16, announces the discovery of an apparently asteroidal object (discovery magnitude ~18.1) by Cristovao Jacques, Eduardo Pimentel, and Joao Ribeiro de Barros on CCD images obtained on Jan. 12.0 UT with a 0.45-m f/2.9 reflector of the Southern Observatory for Near Earth Research (SONEAR) at Oliveira, Brazil. The object has been found to show cometary appearance by CCD astrometrists elsewhere and then also by Jacques et al. The new comet has been designated C/2014 A4 (SONEAR).
