December 1, 2016: The blazar CTA 102 (4C 11.69) has been in an active state in gamma-ray and optical wavelengths since 2015. During 2016, it has had numerous flaring episodes, particularly since late October. It is presently in an unprecedentedly bright optical state, and showing substantially increased emission in gamma-ray and near-infrared wavelengths.
November 9, 2016: Further to AAVSO Alert Notice 545, time series observations of the intermediate polar cataclysmic variable FO Aqr are requested to provide simultaneous coverage of XMM-Newton observations scheduled for 2016 November 13 19:43 UTC to November 14 8:13 UTC.
October 11, 2016: Further to AAVSO Alert Notice 549, observations of the dwarf nova RX And are urgently requested immediately. The system *may* be going into outburst, and confirmation is essential in order to know whether to trigger ToO observations with Chandra and other instrumentation.
September 22, 2016: SN 2016gkg (announced as AT2016gkg) was discovered by Victor Buso (Rosario, Argentina) on 2016 September 20.2484 UT at CCD magnitude (clear filter) 17.6 +/-0.5, rising to 14.5 +/-0.2 on Sep. 21.1398. His discovery was reported to the Transient Name Server by Sebastian Otero (Buenos Aires, Argentina). It was confirmed by ASAS-SN on Sep. 21.29 UT (B. Nicholls (Mt.
S. Zola (Jagiellonian University) et al. (ATel #9489) report that the BL Lac object OJ 287 has emerged from conjunction optically very bright and increasing in brightness, according to their observations made at Mt. Suhora Observatory in August and September 2016.
