Date: Wed, 16 Jun 1999 01:53:41 -0700 (PDT) From: Rock Bush To: mdiers@mdisas, trace_planners@cheyenne.nascom.nasa.gov, local@quake.Stanford.EDU Cc: Carolyn Yale Subject: Report from LaPalma Dick Shine and I have assembled a few images from the last week of observing with the Swedish Vacuum Solar Telescope at La Palma. We haven't had time to polish it, but we thought you would like to see some of the images that we have taken. I have managed to get them transferred to one of our computers at Goddard, and they can be found at: http://mdisas.nascom.nasa.gov/lapalma The following images are suggested to minimize the pain of displaying some of the data because the full gif images are 2 to 3 Mbytes each. In the files below, gband indicates images taken with a filter at 4308 Angstrom with a 12 Angstrom bandpass; c4507 indicates images taken with a filter at 4507 Angstrom with a 10 Angstrom bandpass. The "sunspot.gif" images are selected regions from the full image, the "sm.gif" images are binned versions of the full field. For differences, Dick Shine and I pointed the telescope at Mars one evening after sunset, and took the image labeled "mars_14jun99.gif". gband.10jun99.000824.sunspot.gif c4507.12jun99.000540.sm.gif gband.12jun99.000553.sm.gif c4507.12jun99_112904.sunspot.gif c4507.13jun99_113705.sunspot.gif gband.13jun99_113603.sunspot.gif mars_14jun99.gif The observing run has been successful, the data taken on the 10 and 12th were on the sunspots in the MDI high resolution field. We had two days with runs with reasonable seeing for more than 8 hours. We also observed a C3.9 flare in H alpha on 11 June on the sunspot leaving the MDI high resolution field of view. Dick Shine may be able to get some of those images on the net in the next few days. Regards, Rock ps. I have included full gif images and fits files for selected images for those interested in more detail.
