We have performed an optical CCD imaging survey of star-forming regions ide
ntified through compact reflection nebulae and/or embedded IRAS sources in
order to search for new Herbig-Haro (HH) flows. Here we present the discove
ry of hitherto unknown HH objects in seven of these regions. A bright bow s
hock, HH 461, is found along the axis defined by the previously known HH 16
4 jet from the luminous young A star LkH alpha 198. The little-known cometa
ry nebula PP 11, illuminated by the partly embedded IRAS source 03507+3801
in the Perseus clouds, contains an HH object HH 462, found along the symmet
ry axis of the nebula. A small jet, HH 463, emanates from the recently iden
tified FU Orionis candidate PP 13S, while another HH flow, HH 464/HH 465, a
ppears to originate from the nearby T Tauri star PP 13N. A group of HH obje
cts, HH 466-468, are located around the nebulous young T Tauri binary GK Ta
u. A well-collimated HH jet and an associated bow shock, HH 470, are found
extending from the young nebulous T Tauri star Haro 4-255 in Orion, and a t
iny reflection nebula and associated HH object, HH 469, are located close b
y the deeply embedded Class I source Haro 4-255 FIR. In light of these new
HH flows in Haro 4-255, we re-interpret existing (CO)-C-12 data on this sou
rce in terms of two overlapping molecular outflows. The young star LkH alph
a 316 and the nearby IRAS source 05451+0037 in Orion are found to be associ
ated with a cluster of HH objects, HH 471-474. It is likely that a nearby a
nd previously identified HH object, HH 71, also originates in this region.
Finally, a chain of HH objects, HH 475, is found near the little-studied co
mpact bipolar reflection nebula PP 95 in the Cygnus clouds. The origin of t
his HH chain remains unclear, and HH 475 may equally well be driven by one
of several luminous massive young stars in the region.
