          Dr. Michael Rupen (National Radio Astronomy Observatory, Socorro, 
NM) has informed us that he and his colleagues of the EVLA (Expanded
Very Large Array) Nova Team are carrying out a multiwavelength 
campaign on the Fe II-type nova Nova Oph 2012. They have triggered 
observations with Swift, JVLA (Jansky Very Large Array), SMA 
(Submillimeter Array), and high-resolution optical spectroscopy. 
He is requesting AAVSO observations in support. 

Dr Rupin writes: &quot;We had the first epoch of SMA and spectroscopy 
April 9; the first two Swift observations are scheduled for April 
13 and April 27 UT; we're hoping for the first VLA observation 
later this week. It would be very useful to have fairly regular 
multi-color photometry to follow the overall evolution of the 
source, as well as spectroscopy to track the velocity of the 
ejecta. Spectroscopy on the dates of the Swift observations 
(April 13 and April 27 UT) would be particularly valuable, 
allowing us to compare the temperature of the X-rays with that 
which could be produced either within the ejecta, or between the 
ejecta and any surrounding, relatively stationary circumbinary 
material.&quot;

The EVLA Nova Team (https://safe.nrao.edu/evla/nova/index.shtml) 
aims at consistent, high-quality radio, optical, mm, and X-ray 
coverage of nearby novae. 

The Fe II-type nova Nova Oph 2012 (PNV J17260708-2551454) was 
announced on the IAU CBAT TOCP page 
(http://www.cbat.eps.harvard.edu/unconf/tocp.html), in AAVSO 
Special Notice #273 (Waagen, 
http://www.aavso.org/aavso-special-notice-273), and IAU CBET 3072 
(Daniel W. E. Green, Ed.). Over 650 observations in the AAVSO 
International Database indicate that N Oph 2012, discovered at 
unfiltered magnitude 12.1, reached V=9.0 on April 7 and is 
currently at V=11.8.

Please continue your coverage of this current nova. Multicolor 
photometry is requested, and visual observations are also 
encouraged. If you have spectroscopy capabilities, please observe 
this nova, particularly on the Swift dates given above.

Coordinates: 17 26 07.01  -25 51 42.69 (J2000.0)

Observations may be accessed from the AAVSO website:
viewed (http://www.aavso.org/ql), 
plotted (http://www.aavso.org/lcg), 
or downloaded (http://www.aavso.org/data-download).

Charts may be plotted using the AAVSO Variable Star Plotter (VSP) 
at http://www.aavso.org/vsp.

Until an official name is announced, please report observations 
to the AAVSO International Database as PNV J17260708-2551454 or 
NOVA OPH 2012.
