During the course of ten nights of observing (UT 27 April - 6 May 1996), the KPNO Mayall 4m Telescope was used to image the Hubble Deep Field in the near infrared. The IRIM camera employs a 256 x 256 Rockwell NICMOS-3 HgCdTe array, with a scale of approximately 0".6/pixel at the 4m f/15 Cassegrain focus. ... A paper on the HDF/IRIM data (observations, reductions, catalogs and basic analysis) is in preparation, titled "Near Infrared Properties of the Hubble Deep Field" by Dickinson et al. ...

The Sun is our nearest star and the source of energy for life on Earth. ... For centuries astronomers wondered whether they were clouds floating in the Sun's atmosphere, but we now know that they really are huge regions of magnetic field, about as intense as the field at the poles of an iron magnet. ... Such abrupt events were named solar flares , and what made them especially interesting was that occasionally, after a prominent flare, a magnetic storm would erupt on Earth. ...
