Very high energy (VHE) γ-ray emission from the flat spectrum radio quasar (FSRQ) PKS 1222+21 (4C 21.35, z = 0.432) was detected with the MAGIC Cherenkov telescopes during a short observation (~0.5 hr) performed on 2010 June 17. The MAGIC detection coincides with high-energy MeV/GeV γ-ray activity measured by the Large Area Telescope (LAT) on board

The high-resolution (R ~ 600) Spitzer/IRS spectrum of the bipolar protoplanetary nebula (PN) IRAS 17423-1755 is presented in order to clarify the dominant chemistry (C-rich versus O-rich) of its circumstellar envelope as well as to constrain its evolutionary stage. The high-quality Spitzer/IRS spectrum shows weak 9.7 μm absorption from amorphous

Interstellar absorption lines up to J″= 10 in the (2, 0) band and up to J″= 6 in the (3, 0) band of the C2 A1Πu-X1Σ+g system are detected toward star Cernis 52 (BD +31°640) in the Perseus molecular complex. The star lies in a reddened line of sight where various experiments have detected anomalous microwave emission spatially correlated with dust

Observations were made in 12 runs, from 2003-09-29 to 2004-01-26. (5 data files).

We report on the follow up observations after the report of ~10 mHz quasi-periodic oscillations (QPO -- ATel #3225) in the X-ray light curve of the ongoing outburst of the black hole candidate IGR J17091-3624 (ATel #3144, #3159, #3167, #3203) RXTE/PCA observations performed on March 19th and March 22nd, 2011, show a continuous progression of flare
