V884 Her: an improved ephemeris [Observed: 2 sessions in 2018, 3 in 2017, 6 in 2016, 6 in 2015 ]
Photometric observations of the cataclysmic polar V884 Her are
presented. An improved ephemeris for the eclipses is obtained.
Occultation by Lucina [Observed: 30 Nov 2016]

FO Aqr 2016 low state and recovery [Observed: 10 Jul, 31 Oct, 6, 8 Nov, 26 Dec 2015, 28 Jun, 3, 9, 18, 28]
In 2016, the intermediate polar FO Aqr has been observed in an
unusual low state and slowly recovering. The O-C are compared with those from my previous observations.
BG CMi time keeping [Observed: 2005-2016]
Twelve seasons, from 2005 to 2016, of photometric monitoring of the intermediate polar BG CMi are presented and are compared with previous observations. The spin up of the white dwarf is found to have undergone a major change between 1996 and 2005. There is also some evidence for sideband signals.
