Object confirmed with 21 x 20 seconds unfiltered stacked exposures with 0.28m f/5 SCT + CCD on April 19.148, 2014. Photometry of 17.0 +/- 0.1 with V as reference. Comparison stars are from SDSS g and r data calculated to V. S. Howerton. Image: https://www.flickr.com/photos/watchingthesky/13931569244/

I imaged this new object using a C14+SBIG ST9XE + Cousins r filter + 6x60s and obtained the following results from measurements in Astrometrica RA 14 00 54.49 Dec+40 59 00.7 0.09 0.06 Mag= 16.0R 24 ref stars UCAC-4 Denis Buczynski Tarbatness Observatory MPC Code I81




2014 04 16.425

The object is marginally detected at ~3 sigma level by KAIT on April 16.425 UT with mag R~17.3 +/- 0.3, but no detection on April 14.392 with limiting mag ~17.5, and on April 10.4 with limiting mag ~18.3.




2014 04 19.9279

Follow up observation: 2014 April 19.9279 UT. Astrometric reduction results in end points of R.A. = 54".59 and Decl. = 58' 59".9. An unfiltered magnitude estimate places this new transient at mag +17.2.

Above observation by David Grennan, Raheny Observatory, 0.35-m newtonian and CCD.




2014 04 21.808

This transient was observed on 2014 04 21.808 by Gianluca Masi, Francesca Nocentini and Patrick Schmeer, remotely using the 17"-f/6.8 corrected Dall-Kirkham robotic unit part of the Virtual Telescope Project facility, at Bellatrix Astronomical Observatory in Ceccano, Italy. 120-seconds exposures, unfiltered, show the source at mag. 16.5 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 54.49; 59.8 (J2000.0, mean residuals of 0.2" on both axes).




2014 04 21.276

This possible supernova in NGC 5410 was detected with 5 x 10 min images using a clear filter Photometry: Mag 17.62 +/- 0.21 (V for ref; USNOA2) Astrometry: RA 14 00 54.51 Dec +40 58 59.7 These data were collected remotely by Joseph Brimacombe, Coral Towers Observatory, Cairns, Australia.
