M. Claussen, National Radio Astronomy Observatory (NRAO); K. Healy and S. Starrfield, Arizona State University; and H. E. Bond, Space Telescope Science Institute, report SiO maser observations of the unusual eruptive variable V838 Mon using the NRAO Very Large Array on Sept. 1: "SiO maser emission was first detected by Deguchi et al. (2005, http://xxx.lanl.gov/abs/astro-ph/?0507363) on 2005 Feb. 23, strengthening by Apr. 24. Relative to the April observations, we find that the peak flux in the v=2, J=1-0 SiO transition at 42.82 GHz has increased further by a factor of four to 4.98 ± 0.01 Jy. The peak flux in the v=1, J=1-0 transition at 43.12 GHz has also strengthened by a factor of three to 2.83 ± 0.01 Jy. The maser emission in both transitions is unresolved (angular size < 0".3). Further monitoring with the VLA and the Very Long Baseline Array is planned, and monitoring is encouraged at other wavelengths, especially in the near- and mid-infrared."
