Atomjack is an online science fiction/science fantasy magazine. Current pay rate is $10 per story/poem/article, but in 2009 all accepted works will be paid $20. They accept reprints and simultaneous submissions. Read the full guidelines for more information. To see what the editors like, check out this issue's cover pic, and "Invaders" by Mari Ness.
Atomjack is also currently seeking submissions for its "alternate future" e-anthology, titled The Butterfly Affects. Payment for the anthology is $15 per poem or flash fiction piece and $30 per short story (1,000 to 10,000 words). They will be accepting submissions through May 2009, so you still have some time.
In case you haven't heard, the table of contents for the 2008 Dwarf Stars anthology has been announced. It's quite a collection of poets, including many mainstream haiku poets that I never thought I would see in a speculative anthology. I'm not sure when copies will be mailed out to SFPA members, but if you're not a member (or you want 2 copies) you can order your copy here.
Lastly we have the 2008 Winter Moon Awards for Haiku. There is no website (as of yet) for this contest, but here are the guidelines, listed in the current Haiku Society of America newsletter:
Submit up to 10 unpublished haiku, not being submitted anywhere else, on one sheet of paper. Prizes for the top three poems are $100/$50/$25, and there is no entry fee. Send 2 copies -- one with name and address in the upper left hand corner, and one with just the poems -- to Carolyn Thomas, 7866 Hogan Circle, Hemet CA 92545. Include an SASE for results. All entries must be in hand by December 1st.
