In response to: "A Galaxy [NGC 3310] Blazes With Star Formation"
I observed this galaxy in May during the international telescope meeting
at Vogelsberg here in Germany. This galaxy contains a huge luminous H II
region called "jumbo" (first reported by Balick and Heckman in 1981). This
region is clearly visible on the HST pic. The HII region involves numerous
Super Star Clusters (which are too faint for visual observations). So the
"jumbo" was the intention for my observation (not the galaxy itself).
Here is my note on this galaxy using my 20incher:
Under 6,5mag skies this galaxy reveals an inner very bright roundish glow
with a fainter part to the north which gives the galaxy a oval shape. I
noted a very weak spot at the northern periphery of the galxay (only with
averted vision about 50% of time). This is possibly the region (I compared
my drawing with position in the papers). If so, this may be the most
distant H II region for visual observers. This observation was confirmed
by two other observers. -Best regards, Jens
