(IAAC) Open cluster candidates ( 17 new addictions )
Hello,
Recently, I added some new discoveries to table 3
( various discoverers ) of my "Catalog of Obscure
Star Clusters".
Here's the table ( showing only the mentioned addictions )
as well as the corresponding Bibliographical sources and
some useful comments.

THE eta Cha CLUSTER: A REMARKABLE NEW NEARBY YOUNG OPEN CLUSTER
Aditional Notes :
HIP 37742 = NGC 2451 B
Eta Cha Cl. Includes Br trio of stars Eta Cha, RS Cha and HD 75505
plus 10 Li-rich, H-alpha emission-line, late-type stars
(K4--M5)
D = 97 pc; Age = 2-18 . 10^6 years. Found by ROSAT.
HIP 45080 = a Carinae cluster
HIP 45189 = includes Lambda Vel.
Miller 1 = Alessi J09257-5314! Diam = 1' N* = 8
Miller considered this an OB association, but I think
this is too small and compact for a true assoc.
It is a possible compact mini-cluster in my opinion.
Shorlin 1 Includes two wolf-rayet stars : WR38 and WR38a and several
young, luminous OB stars. According to Steve Shorlin,
this one is 41,000 light years ( 12,570 parsecs ) away
from us!!
Shorlin 2 "possible intermediate age cluster with possible yellow
supergiant
member" ( S. Shorlin ). Near Shorlin 1 ( same HP field ).
HIP 100408 forms possible double cl. with HIP 100833
HIP 100833 forms possible double cl. with HIP 100408
Despite it's probable cluster status, the HIP clusters aren't good for
amateur astronomy becase they are too loose! ( except HIP 37742 and
HIP 45189 ).
