Remarks
Some references may be clicked to view in new window. Roll over index number to view submission details.
1 Otero, Sebastian Alberto Unique slow (400 d.) 6 mag. outburst in 2019. It is either a record breaking DN outburst or —more likely— a more energetic phenomenon than a disk instability event. Non-ejection nova event? (2022ApJ...939....6A)
2 Schmeer, Patrick The reported orbital period of 8.66 h (2019ATel12889....1A) could be some artifact from the data reduction and is likely not a real one (E. Aydi, personal communication).
3 Otero, Sebastian Alberto Slow 2.5 mag. brightening lasting for more than 2 months (starting on April 6, 2019) according to OGLE data (2019ATel12876....1M) and first reported by Gaia. Unusual for a recurrent nova or a dwarf nova.
