A Dormant Captured Oort Cloud Comet Awakens: (18916) 2000 OG44
Colin Orion Chandler, William J. Oldroyd, Chadwick A. Trujillo +2
We report the discovery of activity emanating from (18916) 2000 OG44 (alternately designated 1977 SD), a minor planet previously reported to be both an extinct comet or an asteroid…
The Active Asteroids Citizen Science Program: Overview and First Results
Colin Orion Chandler, Chadwick A. Trujillo, William J. Oldroyd +20
We present the Citizen Science program Active Asteroids and describe discoveries stemming from our ongoing project. Our NASA Partner program is hosted on the Zooniverse online plat…
Do the Outburst Properties of M31N 2008-12a Depend on the Time Since the Previous Eruption?
William A. Burris, Allen W. Shafter, Kamil Hornoch
Photometric observations spanning the UV to the near IR during the nine most recent eruptions (2014-2022) of the extragalactic nova M31N 2008-12a are presented and analyzed in orde…
IRAS 00450+7401 and the mid-infrared fade/burst cycle of R Coronae Borealis-type stars
William A. Burris, Carl Melis, Allen W. Shafter +3
We present optical and infrared imaging and spectroscopy of the R Coronae Borealis-type (R Cor Bor) star IRAS 00450+7401. Optical spectra further confirm its classification as a co…
New Recurrently Active Main-belt Comet 2010 LH15
Colin Orion Chandler, William J. Oldroyd, Henry H. Hsieh +9
We announce the discovery of a main-belt comet (MBC), 2010 LH15 (alternately designated 2010 TJ175). MBCs are a rare type of main-belt asteroid that display comet-like activity, su…
New Active Asteroid 2015 VA108: A Citizen Science Discovery
Colin Orion Chandler, William J. Oldroyd, Chadwick A. Trujillo +6
We announce the discovery of activity, in the form of a distinct cometary tail, emerging from main-belt asteroid 2015 VA108. Activity was first identified by volunteers of the Citi…
Discovery of Dust Emission Activity Emanating from Main-belt Asteroid 2015 FW412
Colin Orion Chandler, Chadwick A. Trujillo, William J. Oldroyd +6
We present the discovery of activity emanating from main-belt asteroid 2015 FW412, a finding stemming from the Citizen Science project Active Asteroids, a NASA Partner program. We…
M31N 1926-07c: A Recurrent Nova in M31 with a 2.8 Year Recurrence Time
Allen W. Shafter, Kamil Hornoch, Hana Kučáková +8
The M31 recurrent nova M31N 1926-07c has had five recorded eruptions. Well-sampled light curves of the two most recent outbursts, in January of 2020 (M31N 2020-01b) and September 2…
The Rate and Spatial Distribution of Novae in M31 as Determined by a Twenty-Year Survey
Travis A. Rector, Allen W. Shafter, William A. Burris +11
A long-term (1995-2016) survey for novae in the nearby Andromeda galaxy (M31) was conducted as part of the Research-Based Science Education initiative. During the course of the sur…
