----------------------------------- Herr_Alien 12 Sep 2019 07:49 Alert Notice 678: V694 Mon (MWC 560) ----------------------------------- Anuntul original (si complet) aici: https://www.aavso.org/aavso-alert-notice-678 Dr. Karovska writes: "MWC 560 is a symbiotic system showing jet/outflow activity. The system has undergone several outbursts since 1990, including a recent one that started in late 2018." An observation of V694 Mon in the AAVSO International Database (the first since May 2019, when it was visual magnitude 9.1 (C. Adib, Porto Alegre, Brazil)) shows the system at 8.795 V +- 0.008 on 2019 Sep. 09.43423 UT (S. Dvorak, Clermont, FL). Its range is 8.88-12.2 V. Bi-weekly photometry will be very much appreciated. UBV (and RI if possible) coverage is needed. Visual observations are also encouraged. Pentru rapoarte de observatii, in afara de a le trimite celor de la AAVSO: http://www.astronomy.ro/forum/viewtopic.php?p=190128#190128 Mai jos sunt harti de localizare si pentru estimari.
