FO Aqr: 2017 season [Observed: 7 June, 28 July, 21, 22 August 2017]
Observations of the intermediate polar FO Aqr are presented for 2017.

FO Aqr time keeping [Observed: 49 sessions from 2004 to 2015]
Twelve seasons, from 2004 to 2015, of photometric monitoring of the intermediate polar FO Aqr are presented and are compared with previous observations. The ambiguities in the cycle counting can be lifted and a new O-C diagram, spanning 34 y,r is presented, along with new ephemerides.

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. is also some evidence for sideband signals.

AO Psc time keeping [Observed: 74 sessions from 2004 to 2014]
Eleven seasons, from 2004 to 2014, of photometric monitoring of the intermediate polar AO Psc are presented and are compared with previous observations. The spin up of the white dwarf is found to be slowing down. The amplitudes of the modulated and non-modulated components of the brightness are found to have undergone a major change in 2007.

AE Aqr [Observed: 13, 16, 17 Jun 2012]
Time-series of this unusual cataclysmic star were obtained with B and V filters. Flares were observed, with the object becoming bluer.

EX Hya [Observed: 9 Feb 2011]
A light curve for this cataclysmic star, classified as both IP and NL, is presented and compared with the ephemeris, after its May 2010 outburst.

EX Hya outburst [Observed: 22, 24 May 2010]

V1432 Aql: an asynchronous polar [Observed: 7, 12, 13, 14, 15 July, 5, 18 Aug, 5, 15 Sept 2007]
Light curves for this magnetic cataclysmic system are presented. They show the eclipses and the spin modulation.

RX J1039.7-0507 [Observed: 1 Feb, 29 March, 3 Apr 2006]
Observations of this faint, large amplitude cataclysmic star with a small telescope are presented.

AE Aqr flares (and HX Aqr) [Observed: 29, 30, 31 Aug 2005]
Time-series of this unusual cataclysmic star were obtained with B and V filters. Flares were observed, with strong color changes.

EX Hya [Observed: 19, 23, 24, 29 May, 6 June 2004]
Light curves for this cataclysmic star, classified as both IP and NL, are presented and compared with the ephemeris.

V2400 Oph [Observations: several sessions between July and Sept 2004]
V2400 Oph is an IP, discless cataclysmic star. It is observed (the data are not very good) to flicker and that the color is V-R=0.3+/-0.1.
