June 12, 2013: Based on your observations, the HST/COS team will be making the final decision tomorrow morning (2013 June 13) whether to observe BD Pav.
Your observations tonight (June 12/13) are CRITICAL. HST/COS is scheduled to observe the eclipsing dwarf nova BD Pav:
BD Pav 2013 June 14 04:40:42 through 09:46:09 UT
If you can observe BD Pav, a few V-band snapshots would be sufficient and very helpful. BD Pav is 15.4V at minimum and 12.4V at maximum.
BD Pav R.A. 18 43 11.919 Dec. -57 30 44.85
Charts may be created using the AAVSO Variable Star Plotter (http://www.aavso.org/vsp ).
