Color image of comet C/2015 F3 (SWAN), obtained from LBVR filter image data, taken on 2015 Apr. 21 (2h40-2h55UT)
with 60-cm, f/3.3 Deltagraph telescope and CCD. Exposure time was 30 seconds in each filter. Image scale is 1.25 arc
sec/pixel. The comet was discovered on images taken with (SWAN) camera on the Solar and Heliospheric Observer (SOHO)
spacecraft last March 5. The object is barely visible on single images, very diffuse and without the nucleus. Its gas
component probably evaporated durig the Sun encounter, leavig only cloud of dust debris.
