February 18. Clear, humid, calm, +3 C, average transparency. Observed for 1 h around 01:00. SQM 21.34. 20" F/5 Obsession, mostly 13 mm Ethos.
NGC 3196. Bratton marks it as one of the most difficult objects in the Herschel catalog. Herschel himself recorded it as "a little doubtful". I could not see it in the 12" last time. Now in the 20 it is a somewhat intermittent EW oval. Mag 16.19B. 676 Mly.
NGC 3216. Similarly not seen last time, although it is larger and much brighter.
NGC 3226 and 3227. Arp 94. H400 reobservation; seen previously in 4". W arm curving toward companion. Opposite arm pointing toward star seen only with 8 mm as a straight segment not extending past the core.
NGC 3239. Arp 263, "Loony Galaxy". In 2012 I observed the supernova and the brightest features in 12". Brightest part just N of star. E of the star on the same edge is an almost equally bright compact object. A fainter one is embedded N of the star in the bright part. Separated cloud like a hook S pointing at companion E. Grainy streak SW, oriented NW-SE. Faint extension of the bright part toward star W.
February 19. Same conditions. 9 new objects observed between 23:30 and 1:00.
NGC 3303, Arp 192. Fainter component NW, touching.
NGC 3338. 8 mm. Enhancements E and W of central core where arms bend. SW arm segment points at star. N arm segment shorter than core.
