A new objec was discovered on the 16 of April at the Crni Vrh Observatory. It appeared very soon to be a new periodic comet, designed P/2010 H2, in an outburst phase.

Giovanni Sostero and Ernesto Guido were among the first to report the cometary nature of the object.

Af[rho] quantity measurements in R and/or I bands are urgently needed to monitor the evolution of the event. Hipparcos solar analogs are highly recommended as reference stars.
