Accidentally came across Junior Red Spot, saw comet Pojmanski

This time only 3 of us, Akarsh, me and the President of our astronomy association had gone to our northern location with the prime purpose of observing and doing some astrophotography, piggyback. Both of us, Akarsh and me were supposed to learn it from our President, who's' very experienced in this field. Also I wished to get the Comet Pojmanski photographed by tracking.

The weather was very bad in the evening up to midnight. There was also lots of light pollution. As a result no photography could be done. So Akarsh and me went on with our usual work, observing. The instrument was the president's 8" f/8 which produced fantastic images and stars as pin-point.

Both of us started with the planetary nebula NGC 2438 in the open cluster M46 (NGC 2437). I roughly knew which side of the open cluster to look for so with very great difficulty could find a 10th magnitude haze within the cluster. All of us saw it later. At night it was the usual session with different types of objects, clusters
and galaxies. Akarsh finished the entire Virgo cluster (while I just dozed off for some time) and observed around a total of 25 galaxies there. Then both of us aimed mainly for some new globulars in the Southern sky. And galaxies randomly here and there as well as in Leo, Ursa Major etc. I saw only a total of around 18 new objects. Some other highlights were : two very faint looking globulars in the same field of view, Pojmanski comet, 1-2 approximately 11.5 magnitude galaxies and very less meteors.

In the morning we waited for Pojmanski wanting to photograph it. But the skies in east were so badly light-polluted that it resembled the city sky. I wanted to find it with the telescope but the ligh-pollution discouraged me in finding it. But still, somehow by moving here and there in the nearby region as given in the finder chart, I came across it with the telescope. It was superb even in lights. The coma was very bright and this time the tail was around 1/4th the field of view of eyepiece (1 degree). The last time I saw it, it was around 1/2 degree long. Jupiter was one of the best highlights ever. So good was the optics of the President's instrument that when the image was steady, I could slightly make out the Red Spot and another spot beside it !! I wanted to know what that tiny spot was, around half the size of the Great Red Spot (GRS). And on top of that, the unevenness (that they are not straight lines) in the two bands of Jupiter were slightly made out as seen in photos. Also I could probably see another very thin band just above the bottom band (that's near to the equator). Very few bands near both the poles also could be seen. These observations were made by both of us. (mostly these were not illusions).

After few days, I came to know that the unknown spot I had seen near to the GRS was infact another new feature on Jupiter, unofficially called Junior Red Spot. I had "discovered" a new feature on Jupiter.

We missed photographing Pojmanski this time. But anyway I hadn't lost hope altogether. We had another comet 73/P Schwassmann Wachmann3  coming our way, we not knowing about the historic approach we were going to witness. It was predicted to be much brighter in May reaching 3-4th magnitude and visible throughout the night.
