[vsnet-alert 17381] Re: ASASSN-14cl: visual observation

[Luca Izzo]

Dear all,

I've observed the ASASSN-14cl transient with a 50cm iTelescope T11 instrument (MPC H06) in B,V and R filters. Obs time = UT 08:03:55 (for the V filter)
Exposures in any single filter was of 60s, with the moon was distant less than 60°.
The transient is visible in all three images.
Ensemble photometry, with 10 comparison stars, selected from images whose magnitudes were obtained from SIMBAD (B,V) and USNO B1 (R) provides the following photometry for the transient

B = 10.62 +- 0.14
V = 10.795 +- 0.12

R1 = 11.05 +- 0.13

Fits files available under request. 

Best Regards
Luca
