Mark Kidger reports on behalf of the "Observadores_cometas Group" that a major new outburst of Comet 29P/Schwassmann-Wachmann has occurred two days before the Herschel Space Observatory is due to observe the comet. The outburst was first reported on 2010 Apr. 16, 19:22UT at R=12.8 in a 10" square aperture by EstevÃ© CortÃ©s and the Grup d'Astronomia de MatarÃ³ (MPC A06, MatarÃ³, Spain), having been last seen at R=16.18 by JosÃ© RamÃ³n Vidal (MPC 945, GijÃ³n, Spain) on 2010 Apr. 14, 23:19UT. It was confirmed by RamÃ³n Naves & Montse CampÃ s (MPC 213, Barcelona, Spain) at R=12.76 on 2010 Apr. 16, 20:20UT; Marius DurÃ¡n (MPC C12, Sabadell, Spain) at R=12.82; and Faustino GarcÃa (MPC J38, Asturias, Spain) at R=12.82 on 2010 Apr. 16, 20:56UT.
On 2010 Apr. 17, 21:01UT Naves & CampÃ s measured R=12.90. This is the 9th largest outburst observed by the Observadores_cometas Group since they started intensive observation of the comet in 2001.
