Monard has monitored this star since its discovery in 2002 but the brightness has always been observed to be in the range 16.5-18.5. Cloud-interrupted time-series unfiltered photometry during the current outburst showed strong light variations within a range of 0.65 magnitudes over a period of 90 minutes, but no cyclic behaviour or superhumps were seen. SUPERNOVA 2008if IN MCG -01-24-10 Discovery by the CHASE Project of a possible supernova (CBET 1619): SN 2008 UT R.A. (2000.0) Decl. Mag.

Itagaki (Japan, 0.60-m f/5.7 reflector) obtained an unfiltered CCD image (limiting mag 19.0) on Dec. 16.698 that shows it at mag 16.0 Guy Hurst also reports a photometric set of measures for 2008 Dec 28.173UT of magnitude 16.1V +/-0.1 using the Bradford Robotic Telescope. GENERAL CATALOGUE OF VARIABLE STARS (GCVS) The GCVS has been moved to the regularly-updated section of the Strasbourg catalogue-query service VizieR. The current version contains 41638 stars in the main catalogue plus 26017 NSV stars according to Brian Skiff. Further information can be found at: http://cdsarc.u-strasbg.fr/viz-bin/Cat?B/gcvs The old site of the GCVS at: http://www.sai.msu.su/groups/cluster/gcvs/gcvs/ is still active and it may be advisable to check both sites for the time being in any check for newly suspected variable objects until it is clear that the new site has totally replaced the earlier version. We continue to receive false alarms of new variables which are already known and, in addition to the above, checking the AAVSO International Variable Star Index at: http://www.aavso.org/vsx/ is worthwhile for objects announced but not yet accepted into the GCVS or NSV listings.
