CVOM: OGLE-IV REAL TIME MONITORING OF CATACLYSMIC VARIABLES



OGLE Monitoring system of cataclysmic variable stars (CVOM) is the OGLE real time data analysis utility designed to provide real time photometry of all types of cataclysmic variable stars located in the fields regularly monitored by the OGLE-IV Survey (see maps).

Cataclysmic variable stars are known to undergo prominent eruptions with amplitude reaching a few magnitudes. Such eruptions are unpredictable and the OGLE CVOM system can serve as the Early Warning System for these stars allowing full variety of follow-up observations in crucial phases of eruption.

The list of monitored objects can be easily extended. Input from the astronomical community is welcome. The photometry is updated regularly, typically after every clear night during the target observing season.

The photometric data are taken in the I-band. OGLE-IV I-band interference filter very closely reproduces the standard system band. Presented here photometry comes from the image reduction obtained in almost real time at the telescope and it is only roughly calibrated (accuracy of the zero point is estimated to be +/-0.15 mag).


Photometric data presented here can also be found on OGLE Anonymous FTP Archive.


If you have any questions or comments, send us a message.


The OGLE CVOM photometry is provided here for information purposes only to facilitate the community monitoring of those cataclysmic variables and follow up observations. Please contact us if you want to use the data for publication. We may require to be co-authors when our photometry is important for analysis.

When referring to the OGLE CVOM system, please cite the paper by Mrůz et al., 2015, Acta Astron., 65, 313 and provide the WWW address of the CVOM system or the OGLE WWW home page.
