Nova Delphini 2013 (also named V339 Del) is the biggest cosmic event in variable star astronomy this year, and this naked-eye nova is providing the community a wealth of new data on this important class of objects. The amateur astronomical community has made an enormous contribution of data for Nova Del so far, and now is a good time to review all that's happened so far in this nova outburst, and how the amateur community has played a role.
Carey Chiselbrook (CCY; Georgia, United States) reports via the AAVSO Forums that the WZ Sge-type variable UZ Bootis is in outburst. It was observed visually at magnitude 12.8 on 2013 Jul 26 02:00 UT (JD 2456499.58194). The outburst was confirmed by Walter MacDonald (MDW; Ontario, Canada) imaged the field and found UZ Boo at V=12.69 03:25 UT (JD 2456499.6394). Observations of UZ Bootis -- both visual estimates and CCD time series -- are encouraged throughout the outburst.
June 26, 2013: Dr. Noel Richardson (Université de Montréal) is helping coordinate a very large ProAm campaign (over 20 professional and amateur astronomers) this summer on three bright Wolf Rayet stars in Cygnus. Dr. Richardson, fellow co-PIs Drs. Tony Moffat (Université de Montréal), Nicole St.-Louis (Université de Montréal), and Thomas Eversberg (Schnoerringen Telescope Science Institute, Waldbroel, Germany), and their colleagues invite AAVSO spectroscopists and photometrists to participate in this campaign.
January 16, 2013: Dr. Péter Ábrahám (Konkoly Observatory, Budapest, Hungary) has requested the assistance of AAVSO observers in monitoring eight young stars in Chamaeleon in support of photometry he and his colleagues will be obtaining with the VLT/ISAAC (infrared) and Herschel Space Observatory (far-infrared) during January-February 2013.
January 4, 2013: Dr. Bob Zavala (U.S. Naval Observatory, Flagstaff) has requested AAVSO assistance in obtaining multicolor photometry of the bright triple system b Per in order to prepare for and detect a possible eclipse of the AB components by the C component predicted for 2013 January 23. At 4.5V, b Per, which is also a radio source, is an excellent target for photoelectric photometrists and DSLR observers.
