NGC 4622

[akarsh]

Hi folks

I came across this galaxy today in a lecture, and I was quite impressed to see these perfect circular spiral arms in the DSS:
http://archive.stsci.edu/cgi-bin/dss_search?v=poss2ukstu_blue&r=12+42+37.62&d=-40+44+39.2&e=J2000&h=15.0&w=15.0&f=gif&c=none&fov=NONE&v3=

Comparing with other DSS images, my guess would be that this requires > 30" aperture to see the spiral features, but I was just curious if someone had succeeded in observing the arms. Both negative and positive reports will help.

(I should be thinking of Fall galaxies instead...)

Regards

4" - no spiral ;)

I was doing a rushed survey of the Centaurus cluster from Australia, but no arm structure noted in a 24".

24" (4/12/08 - Magellan Observatory, Australia): at 260x this member of the Centaurus cluster (AGC 3526) appeared bright, fairly large, round, sharply concentrated with a very bright core, halo extends to 1.5'. NGC 4616 lies 7' NW and NGC 4603D is a similar distance SW (both viewed).

Observed from California so it's rather extincted and saw no arms. I was walking the Centaurus Chain which is a nice walk with brighter end-ish members of Ngc4603 then on wide arch up to N4622 and on to N4650A and so on to ESO 322-75 (with assorted other dimmer galaxies along that basic path.

We took a look at NGC 4622 with a 24" from Hakos, Namibia in 2016. I was very curious about the unique spiral arms. It was much more than just a brief look but the observation was negative. We didn't see any sign of the spiral structure.
