Abstract
198 spectra of 23 symbiotic stars at resolution from 500 to 15000 were obtained during 2019-Q1 by 18 observers. AG Dra is monitored before the expected outburst in 2019. At the current date (2019-05-18) no sign of outburst has been detected. From medium resolution spectra we have detected the appearence of an emission line in the red edge of He I 5016 during outbursts. The identification of the line is discussed. AX Per soon after the end of its eclipse has been detected in strong classical outburst, characterized by the weakening of high emission lines [Fe VII]. CH Cyg is in low luminosity, several spectra have been obtained during a short flare. V694 Mon, in high luminosity, has been monitored at high cadence during the season. The profiles of Balmer and Fe II lines is unusual, showing a classical P Cygni profile and the disappearance of the broad blue absorption lines.

TCP J05390410+4748030 Dwarf nova in outburst
Berardi, P.; Franco, L.
Abstract
Paolo Berardi obtained a spectrum (Lhires III, 150 l/mm, R = 600) on 2019-03-15.759 typical of a dwarf nova in outburst: Ha and Hb in emission (with perhaps a weak broad absorption), as well as He I 5856, 6678, He II 4686 and the complex NIII/CIII. The FWHM of the Ha and He I 6678 emissions are respectively 900 km.s^-1 and 800 km.s^-1. The decline of the outburst is monitored with flux calibrated spectra.

New Online Database of Symbiotic Variables
Merc, J.; Gàlis, R.; Wolf, M.
Abstract
We have decided to prepare a new, online database of the galactic and extragalactic symbiotic. In addition to the catalog of data for all known symbiotic systems with consistent references, we created a web-portal for easy access to this information.
