[vsnet-outburst 11092] V1032 Oph: eclipsing SU UMa, more details

[Taichi Kato]

   Enrique de Miguel Agustino has reported further details, clearly
demonstrating the eclipsing SU UMa-type nature of this object.
I feed that an alias 0.08106(5) d better express the observation.
Using this orbital period, we obtained a superhump period of 0.0861 d.
These results need to be confirmed by further observations.

Clear UGSU+E behaviour in this run.
See comments below.

Enrique

Variable:     V1032 Oph
Date:         03-04 April
Comp  star:   USNO-A2.0 0825-09356260 (16:25:55.77 -03:53:32.2) with  
12.82R
Check star:   USNO-A2.0 0825-09353329 (16:25:42.04 -03:53:28.1) with  
12.18R
Integ time:   60s
Instrument:   0.25 m reflector f/4.8
Camera:       QSI-516ws
Filter:       Clear
Observatory:  Huelva (Spain)
Comments:     Excellent observing conditions. Data of better quality
               than those in previous runs, where the moonlight and
               occasional clouds gave way to relatively large  
uncertainties.
               The run neatly confirms the UGSU+E nature of V1032 Oph !!
               Run covering about 2 hours (the sun is about to wake  
up ...)
               In addition to the eclipses, V1032 is clearly exhibiting
               superhumps. There is strong evidence of a second eclipse
               by the end of the run, but its location can not be  
located
               accurately due to sunlight (I do not include timing of
               this minimum below).
               Times of minima of the eclipses are:

                          JD                date (UT)
               run01  2455286.67964(17) March 31 04h 18m 41s
               run03  2455290.65062(14) April 04 03h 36m 52s

               Note that heliocentric corrections have not been applied.
               Merging data from run01 and run03, I find an orbital
               period of P_orb=0.0795(3). More data is clearly needed to
               refine this value. Keep an eye on this target!!!
